1. Introduction
Quake, QuakeWorld and Quake II are tremendously popular 3D action
games developed by id Software.
If you're not familiar with the Quake games, there are better places
than this HOWTO to learn about the basics. See section ``Other
Sources of Information'' below for a list of some of these better
places.
This document assumes you have Linux up and running, and in some cases
the X Window System as well. X is not required to run these games,
but it's a nice way to test a basic installation. If you are not
running X, you may safely skip over any references to it.
Sections of this document that were updated in the last revision have
a ** after the section heading. Sections updated in the revision
prior to the last are marked with a ++.
1.1. Feedback,Comments, Corrections
This document certainly does not contain everything there is to know
about Linux Quake. With your help, though, we can bring it closer to
that ideal. We want this HOWTO to be as complete and accurate as
possible, so if you notice mistakes or omissions, please bring them to
our attention.
Questions, comments, or corrections should be sent to Bob Zimbinski
(bobz@mr.net) or Mike Hallock (mikeh@medina.net). Constructive
criticism is welcome. Flames are not.

2. Quake/Quakeworld
To install Quake on your Linux system, you'll need some flavor of the
official Quake distribution from id. This will be either the retail
DOS/Windows CD-ROM that you bought at your favorite software store, or
the shareware version you downloaded from the net (see ``below'' for
details on acquiring the shareware version). Alternatively, if
you've already got Quake installed on a DOS/Windows machine, you can
use the relevant files from that installation.
2.1. Minimum Requirements
You will need, as a bare minimum, the following:
· A Pentium 90 or better (133 recommended) computer
· 16 MB RAM (24 recommended)
· The Quake CD-ROM or the shareware version (quake106.zip)
· Linux kernel version 2.0.24 or later
· libc 5.2.18 or later
· One of the following:
· X11R5 or later (for xquake)
· SVGAlib 1.2.0 or later (for squake and glquake)
· 30-80 megabytes free disk space (depends on how you install)
· Access to the root account of the machine you're installing on
Optional:
· A supported soundcard
· A 3Dfx VooDoo Graphics or VooDoo2 3D graphics accelerator card.
· Mesa 2.6 or later (for glquake)
2.2. Installing Quake

2.2.2. Create the Installation Directory ++
The first thing you'll need to do is decide where you want to install
Quake. Lots of folks like to put it in /usr/games/quake. Anal system
administrator that I am, I choose to install anything that's not part
of my Linux distribution under /usr/local. So for me, Quake goes in
/usr/local/games/quake. If you choose to install somewhere else,
please substitute the appropriate path wherever /usr/local/games/quake
is mentioned.
Note to Redhat users: If you plan on installing QuakeWorld from the
rpm packages, you should probably install Quake in
/usr/local/games/quake, since the rpms install to this directory by
default.
So go ahead and create the directory you'll install Quake in, and cd
to it. The rest of these instructions will assume that this is your
current directory.
mkdir /usr/local/games/quake
cd /usr/local/games/quake
2.2.3. Installing From a Quake CD ++
If you're installing from a Quake CD-ROM, read on. Otherwise you have
permission to skip this section.
There are at least two versions of the Quake CD in circulation. I've
got one from the early days that has Quake version 1.01 on it. Iv'e
seen other CDs that contain version 1.06. You have 1.01 if you see
files on your CD called quake101.1 and quake101.2. If instead you see
a file called resource.1, you have a newer CD. Mount your Quake CD
now and determine which version you've got. In the example below,
replace /dev/cdrom and /mnt/cdrom with the device file and mount point
appropriate for your sysem:
mount -t iso9660 /dev/cdrom /mnt/cdrom
ls /mnt/cdrom
· If you have a resource.1 file on your CD, you can skip ahead to the
next bullet. For a version 1.01 CD, you'll need to download the
Quake shareware package to update the .pak files after the
installation. The last bullet in this section explains this.
· Concatenate the two resource files from your CD to a single file on
your hard disk:
cat /mnt/cdrom/quake101.1 /mnt/cdrom/quake101.2 > resource.1
· Now continue on to the next paragraph, but when I refer to
/mnt/cdrom/resource.1, you should use
/usr/local/games/quake/resource.1 instead.
· Now it's time to extract the Quake files. The resource.1 file on
your CD is really an lha archive (lha is a file compression and
archiving format like zip or tar). We'll use the lha(1) command to
extract it. If lha is not already installed on your system, you
can get it from
ftp://sunsite.unc.edu/pub/Linux/utils/compress/lha-1.00.tar.Z.
lha e /mnt/cdrom/resource.1
When lha is done, your Quake directory will contain a bunch of new
files. A directory called id1/ will also be created. The files in
this directory are the only ones that are important for Linux Quake,
so you can safely remove everything else. If you're totally new to
Quake, or even if you're not, you may want to hang on to the *.txt
files. On my system, I throw all the readmes that accumulate into a
doc/ directory. So:
cd /usr/local/games/quake
mkdir doc
mv *.txt doc
rm -f *
· If you installed from a version 1.01 CD, now you need to overwrite
your id1/pak0.pak file with the one from the Quake shareware
version. Install the shareware version as described in ``Shareware
Version Install'', only install it in some temporary directory so
you don't overwrite your real Quake files. When you've extracted
all the shareware files, copy the id1/pak0.pak file from the
temporary shareware directory to your /usr/local/games/quake/id1
directory. After that, you can erase the temporary shareware
files.
That's it for installing from the CD. You can jump ahead to section
"``Installing the Linux Binaries''" now.
2.2.4. DOS/Windows to Linux Install
If you have Quake installed under Windows or DOS on a different
machine, you can transfer the files in quake\id1\ to your Linux system
via FTP or some other mechanism. Keep in mind that the filenames on
your Linux system must be in lower case for Quake to find them, so you
may have to rename them after the transfer. Also note that it may be
necessary to delete your DOS/Win installation after you do this to
remain in compliance with the terms of id's software license. It's
not my fault if you do something illegal.
If your DOS/Win and Linux systems are on the same machine, you have
two options: copy the files from your DOS/Windows partition to your
Linux partition, or link to the necessary files from Linux. Both
options will work equally well. You just save around 50 megabytes of
disk space when you link instead of copy.
Whatever you choose to do, start by cd'ing to your Quake directory and
creating a new directory below it called id1:
cd /usr/local/games/quake
mkdir id1
· If you want to copy the files from your DOS/Windows partition, do
something like this:
cp /win95/games/quake/id1/*.pak id1
· To create links to your DOS/Windows Quake files instead, do this:
cd id1
ln -s /win95/games/quake/id1/*.pak .
Replace /win95/games/quake with the correct path to your DOS/Windows
partition and Quake installation directory.
The Quake data files are now installed. Move ahead to "``Installing
the Linux Binaries''".
2.2.5. Shareware Version Install
The single-episode shareware version of Quake is freely available for
download from id's ftp site. It has all the features of the full
version, with a couple of major limitations: You can't play
QuakeWorld with it, and you can't play custom or modified levels.
Installing the shareware version of Quake isn't really much different
than installing from the CD.
See section ``Download the Necessary Files'' for the location of the
shareware distribution. Download it and extract it to your Quake
directory:
cd /usr/local/games/quake
unzip -L /wherever/you/put/it/quake106.zip
Now you've got (among others) a file called resource.1 that's really
an lha archive (lha is a file compression and archiving format like
zip or tar). We'll use the lha(1) command to extract it. If lha is
not already installed on your system, you can get it from
ftp://sunsite.unc.edu/pub/Linux/utils/compress/lha-1.00.tar.Z.
lha e resource.1
When lha is done, your Quake directory will contain a bunch of new
files. A directory called id1/ will also be created. The files in
this directory are the only ones that are important for Linux Quake,
so you can safely remove everything else. If you're totally new to
Quake, or even if you're not, you may want to hang on to the *.txt
files. On my system, I throw all the readmes that accumulate into a
doc/ subdirectory. So:
cd /usr/local/games/quake
mkdir doc
mv *.txt doc
rm -f *
Now you're ready to install the Linux binaries.
2.3. Adding the Linux Binaries
Decide which of the three flavors of Quake you'd like to install:
· X11 Quake allows you to run Quake in a window on your X desktop.
It's the least exciting client, but it's a great, safe way to test
your installation.
· Squake is the SVGAlib Quake client. It runs full screen on your
console.
· GLQuake is the OpenGL Quake client, the One True Way to play Quake
if you have a 3Dfx accellerator card.
Download the packages you want (see section ``Download the Necessary
Files'') and extract them to your Quake directory like so:
cd /usr/local/games/quake
tar -xzf XXXX-i386-unknown-linux2.0.tar.gz
2.4. Setting Permissions
Quake and QuakeWorld servers can be run by any user. The Quake
clients, however, need access to your sound and graphics cards, which
requires privileges that normal users don't have. One (bad) way to
deal with this is to always run Quake as root. Responsible system
administrators will cringe at this filthy suggestion. Making the
Quake binaries setuid root is a more acceptable solution. Quake can
then be run by regular users and still have the privileges it needs to
access the sound and graphics devices. Setuid presents a security
risk, though. A clever user could exploit a bug or security hole in
Quake to gain root access to your system. Of course, if you don't run
a multi-user system, this is may not be a big concern.
squake is the only Quake client that must be run with root
permissions. With a little work, you can run the X and GL clients
without setuid. ``Running X and GL games without setuid'' in the Tips
and Tricks section tells how to make this work.
If you plan to run squake, make it setuid root with the following
commands:
chown root squake
chmod 4755 squake
If you've decided it's ok to run quake.x11 and glquake setuid root on
your system, you can repeat the above commands for these binaries as
well.
2.5. X11 Quake
If you installed the X11 client, now's a good time to try it out. You
may need to do further configuration for glquake and squake, but at
this point quake.x11 should be ready to go.
cd /usr/local/games/quake
./quake.x11
If all is well, a small Quake window should appear with the first demo
running in it. You should hear sound effects and possibly music, if
the CD is mounted. If any of this fails to occur, please see the
``Troubleshooting'' section for help.
2.6. SVGAlib Quake
Both squake and glquake require SVGAlib to run (glquake uses SVGAlib
to process keyboard and mouse input, in case you're wondering).
SVGAlib comes with most modern Linux distributions, and must be
properly configured before squake or glquake will run correctly.
libvga.config is SVGAlib's configuration file. On most systems you'll
find it in either /etc or /etc/vga. Make sure the mouse, monitor, and
video card settings in this file are correct for your system. See the
SVGAlib documentation for more details.
If you don't already have SVGAlib on your system, download it from the
location mentioned in ``the files section'' above. If you have a
RedHat 5.x or other glibc-based Linux distribution, see ``Glibc,
RedHat 5.x, Debian 2 considerations'' in the Troubleshooting/FAQs
section for important information about compiling libraries for use
with Quake. A precompiled libc5 SVGAlib binary is available at
http://sunsite.unc.edu/pub/Linux/libs/graphics/svgalib-1.3.0.libc5.bin.tar.gz
for those who don't want to deal with the hassle of compiling for
libc5.
You should run squake from a virtual console. It won't run from X
unless you're root when you start it. And running a game as the root
user is something that should be avoided. So if you're in X, do a
CTRL+ALT+F1, login and then:
cd /usr/local/games/quake
./squake
``Running SVGA and GL games from X'' in the Tips & Tricks section
below explains how to launch SVGA and GL Quake from X without manually
switching to a virtual console.
2.7. GLQuake
Hardware-accelerated OpenGL Quake is Quake the way God intended it to
be. There is no substitute, and once you've experienced it there's no
going back.
To run glquake, you need a 3D card with the Voodoo, Voodoo2 or Voodoo
Rush graphics chipset on it. There are specific issues to be dealt
with if you have a Voodoo Rush card, and I won't go into them now
because frankly, I wouldn't know what I was talking about. A future
version of this HOWTO will cover Rush issues (If somebody wants to
write about Voodoo Rush issues, I'll gladly include it here).
The SVGAlib, Glide, and Mesa libraries must all be installed and
configured properly on your system for glquake to work. The following
sections will very briefly cover what you need to do to get them
going.
Bernd Kreimeier's (bk@gamers.org) Linux 3Dfx HOWTO
(http://www.gamers.org/dEngine/xf3D/howto/3Dfx-HOWTO.html) is good
source for further information.
The 3dfx.glide.linux newsgroup on the 3dfx news server (news.3dfx.com)
is another good source of information about the intersection of Linux,
glide, Mesa and Quake.
2.7.1. SVGAlib
glquake uses SVGAlib to get input from the mouse and keyboard, so
you'll need to configure it as outlined in section ``SVGAlib Quake''.
2.7.2. Glide
Glide is a library that provides an API for programming 3Dfx based
cards. If you want the Mesa graphics library to use your 3Dfx card,
you've gotta have it.
The latest version of glide can always be found at
http://glide.xxedgexx.com/3DfxRPMS.html. Select the package(s)
appropriate for your system, and install according to the instructions
on the web page.
Note that unless you download the 3Dfx device driver package in
addition to the Glide library, you will only be able to run Glide
applications (like GLQuake) as root. Install the /dev/3dfx module and
you can play GLQuake as a regular user.
Once you have glide installed, try out the test program that comes
with it. Remember this program: it's a good way to reset your
display if you ever have a glide application (like GLQuake) crash and
leave your screen switched off. NOTE: run this test from a VC, not X!
It's possible for the test app to lose mouse and keyboard focus in X,
and then you'll have no way of shutting it down.
/usr/local/glide/bin/test3Dfx
Your screen should turn blue and prompt you to hit any key. After you
press a key you should be returned to the prompt. 3dfx.glide.linux on
3dfx's news server (news.3dfx.com) is a great source of information
for Linux glide-specific problems.
2.7.3. Mesa
Once glide's installed, you need to install Mesa, a free OpenGL
implementation by Brian Paul (brianp@elastic.avid.com). Luckily, you
won't have to look far, because Mesa 2.6 is included with the QLQuake
& QuakeWorld binaries. All you have to do is move it to the right
place:
cd /usr/local/games/quake
cp libMesaGL.so.2.6 /usr/local/lib
ldconfig
If you want to upgrade Mesa to a more recent version (Mesa 3.0 is the
most recent version as of this writing), you can download the latest
from ftp://iris.ssec.wisc.edu/pub/Mesa If you have a RedHat 5.x or
other glibc-based Linux distribution, see ``Glibc, RedHat 5.x, Debian
2 considerations'' in the Troubleshooting/FAQs section for important
information about compiling libraries for Quake.
After you've built it according to the instructions, you will have to
do two things:
· Remove your old Mesa installation. If you previously installed a
libMesaGL.so.2.6 as described above, you must remove it or Quake
may not use the new version.
cd /usr/local/lib/
rm -f libMesaGL.so.2*
· If the new Mesa has a major version number that's greater than 2,
you need to create a link to it with the name libMesaGL.so.2:
cd /usr/local/lib/
ln -s /wherever/you/installed/it/libMesaGL.so.3.0 libMesaGL.so.2
ldconfig
Now switch to a VC (CTRL+ALT+F1) and start glquake.
cd /usr/local/games/quake
./glquake
2.8. Linux-Specific Command Line Options
This section covers command line options that are specific to the
Linux versions of Quake. There are plenty of other Quake options, but
they're beyond the scope of this HOWTO. Check out some of the sites
listed in section ``General Quake Information'' for this kind of
information.
-mem num
Specify memory in megabytes to allocate (default is 8MB, which
should be fine for most needs).
-nostdout
Don't do any output to stdout. Use this if you don't want all
the console output dumped to your terminal.
-mdev device
Mouse device, default is /dev/mouse
-mrate speed
Mouse baud rate, default is 1200
-cddev device
CD device, default is /dev/cdrom
-mode num
Use indicated video mode (squake only)
-nokdb
Don't initialize keyboard
-sndbits 8 or 16
Set sound bit sample size. Default is 16 if supported.
-sndspeed speed
Set sound speed. Usual values are 8000, 11025, 22051 and 44100.
Default is 11025.
-sndmono
Set mono sound
-sndstereo
Set stereo sound (default if supported)
2.9. QuakeWorld **
http://www.quakeworld.net says it better than I could:
QuakeWorld is an Internet multi-player specific version of
Quake. While the original version of Quake can be played
over the Internet, modem users - the majority of players,
had less than satisfactory play. Symptoms like excessive lag
- actions actually happening much later than you did them;
packet loss - the game would freeze and resume several sec­
onds later; and various other difficulties plagued users.
After realizing how many people played Quake on the inter­
net, and how many wanted to, but couldn't due to the play
being unsatisfactory, John Carmack of id Software decided to
create a version of Quake that was optimized for the average
modem Internet player. This Internet specific version does
only 1 thing, play deathmatch games over a TCP/IP network
such as the Internet. It has no support for solo play, and
you can't do anything with out connecting to a special
server.
You need the full, registered or retail version of Quake to play
QuakeWorld, and a Linux QuakeWorld client. QuakeWorld clients come in
the same flavors (X11, SVGAlib and Mesa) as normal Quake, but they're
all bundled together in one package, so you only need to download one
file. However, you've got four packages to choose from:
· a libc5 tar.gz package
· a glibc tar.gz package
· a libc5 rpm package
· a glibc rpm package
Install just one of these packages. Each contains the same files,
they're just linked against different libraries. Redhat 5.x users
should choose the the glibc rpm package. Users of glibc based systems
without rpm support should use the glibc tar package. The libc5 rpm
is for Redhat distributions prior to 5.0 and other distributions that
use the rpm package format. The libc5 tar.gz package is for Slackware
and everyone else.
See the ``Download the Necessary Files'' section for the location of
the Linux Quakeworld files.
The prerequisites and configuration for these binaries are the same as
for Quake, so refer to the previous sections for help on setting up
SVGAlib or glide/Mesa.
2.9.1. Installing the RPM packages ++
Installation of the rpm packages should be as simple as:
su root
rpm -Uvh qwcl-xxxxx.i386.rpm
qwcl, glqwcl and glqwcl.glx will be installed setuid root so that they
can access the graphics devices on your system. The X and GL clients
can be run without root privileges if you follow the instructions in
``Running X and GL games without setuid'' below.
Rpm may complain that it can't find libglide2x.so. The Glide library
is only necessary if you have a 3Dfx card and want to run QuakeWorld
in GL mode (glqwcl). If you don't plan to use the GL mode, you can
override the glide dependency with the --nodeps option:
su root
rpm -Uvh qwcl-xxxxx.i386.rpm --nodeps
2.9.2. Installing the tar.gz packages ++
To install, just untar the file in your Quake directory. Do it as
root so the proper file permissions get set:
cd /usr/local/games/quake
su root
tar -xzf qwcl2.21-i386-unknown-linux2.0.tar.gz
qwcl, glqwcl and glqwcl.glx will be installed setuid root so that they
can access the graphics devices on your system. The GL and X clients
can be run without root privileges if you follow the instructions in
``Running X and GL games without setuid'' below.
2.9.3. Running QuakeWorld ++
Once QuakeWorld is installed alongside your Quake files, you can start
it up like:
./qwcl +connect some.server.address
See section ``Related Software'' for info about some nifty front ends
for QuakeWorld that make finding servers easy.
· lib3dfxgl.so **
With Quakeworld version 2.30, an alternative to the Mesa library is
available. lib3dfxgl.so is a mini-GL driver optimized for Quake
that provides slightly better framerates than Mesa. This is a port
of a driver that 3Dfx developed for Quake under Windows, and
apparently not all of its features work properly yet. So hopefully
we can expect its performance to improve with time.
Like Mesa, lib3dfxgl.so requires Glide in order to access your 3Dfx
card. The Quakeworld packages come with a script, glqwcl.3dfxgl
for running Quakeworld with this library on glibc systems. The
next paragraph explains how to run Quakeworld with lib3dfxgl.so on
a libc5 system. On a glibc system in order for this script to
work,the glqwcl executable must not be setuid, nor should you run
it as root. glqwcl will silently load Mesa rather than
lib3dfxgl.so if it runs with root permissions. This non-root
requirement implies that you have the /dev/3dfx driver installed.
On a libc5 system, you need to create a symbolic link to
lib3dfxgl.so called libMesaGL.so.2 like so:
cd /usr/local/games/quake
ln -sf lib3dfxgl.so libMesaGL.so.2
Then start Quakeworld from a script that tells $LD_LIBRARY_PATH to
look in the current directory:
______________________________________________________________________
#!/bin/sh
LD_LIBRARY_PATH=".:$LD_LIBRARY_PATH" ./glqwcl $*
______________________________________________________________________
You can tell which driver is being loaded by looking for output like
the following in your console as Quakeworld starts:
GL_VENDOR: 3Dfx Interactive Inc.
GL_RENDERER: 3Dfx Interactive Voodoo^2(tm)
GL_VERSION: 1.1
GL_EXTENSIONS: 3DFX_set_global_palette WGL_EXT_swap_control GL_EXT_paletted_texture GL_EXT_shared_texture_palette GL_SGIS_multitexture
If GL_VENDOR says Brian Paul rather than 3Dfx Interactive Inc., that
means Mesa is still being used rather than the miniport dirver.
· glqwcl.glx **
glqwcl.glx is linked against standard OpenGL libraries instead of
Mesa. This allows Quakeworld to run on other 3D hardware that is
supported by other OpenGL implementations. At this time, I dont'
know of any OpenGL implementations that support hardware other than
3Dfx, but this renderer ensures that when they appear, we'll be
able to play Quakeworld with them.
This is a GLX application, and as such, must be run from X.
You can use this client with Mesa/3Dfx if you install Mesa and
Glide as explained in the previous section, then set the
$MESA_GLX_FX environment variable to "fullscreen" before you run
quake2:
export MESA_GLX_FX=fullscreen
./glqwcl.glx +_windowed_mouse 1
Why the +_windowed_mouse 1 option? Remember that this is an X
application which happens to use your 3Dfx card. Even though the
display takes up your entire screen, Quakeworld is stil running in a
window. This means that if you're not very careful, you could move
the mouse pointer outside the Quakeworld window, and Quakeworld will
suddenly stop responding to mouse and keyboard input.
+_windowed_mouse 1 avoids this problem by telling glqwcl.glx to grab
the mouse and not let it move outside its window.
2.10. Servers
Most, if not all, existing information about running a DOS/Windows QW
server is equally applicable to running a Linux server.
To start a QuakeWorld server, simply do:
./qwsv
The official QuakeWorld server manual lives at
http://qwcentral.stomped.com.
2.11. Mods & Addons
One of the very cool things about the Quake games is that the authors
made them easily extensible. End users can create their own levels,
add new weapons or monsters, or even completely change the rules of
the game.
2.11.1. Capture the Flag
This is my favorite variation of both Quake and Quake 2. Instead of
just running around and killing everyone you meet (which definitely
has its merits, don't get me wrong!), CTF is team-based and more
strategic. Dave 'Zoid' Kirsch, also the maintainer of the Linux Quake
ports, created this mod.
Everything you need to know about CTF can be found at
http://captured.com/threewave/ You need
ftp://ftp.cdrom.com/pub/quake/planetquake/threewave/ctf/client/3wctfc.zip
to play. To install the client piece of CTF, simply create a
directory called ctf in your Quake directory and unzip the 3wctfc.zip
file there. The accompanying readme.txt file is chock full of good
information.
cd /usr/local/games/quake
mkdir ctf
cd ctf
unzip -L /wherever/you/put/it/3wctfc.zip
For information on running a CTF server, see the web pages mentioned
above.
2.11.2. Mission Packs **
Activision released two add-on packs of extra levels for Quake,
Scourge of Armagon and Dissolution of Eternity.
· Mission Pack 1: The Scourge of Armagon Assuming your CD is mounted
on /mnt/cdrom and Quake is installed in /usr/local/games/quake:
cd /usr/local/games/quake
mkdir hipnotic
cp /mnt/cdrom/hipnotic/pak0.pak hipnotic
cp /mnt/cdrom/hipnotic/config.cfg hipnotic
Play the mission pack like this:
cd /usr/local/games/quake
./quake.x11 -game hipnotic
· Mission Pack 2: Dissolution of Eternity Installing the second
mission pack is pretty much the same procedure as installing the
first. Follow the directions for Mission Pack 1, but replace the
word hipnotic with the word rogue, and skip the config.cfg step, as
this file isn't included on the Mission Pack 2 CD.
2.11.3. Quake Tools
Anybody care to contribute some info about qcc, bsp and all that?
3. Quake II
To install Quake II on your Linux system, you'll need some flavor of
the official Quake II distribution from id. This will be either the
retail Windows CD-ROM that you bought at your favorite software store,
or the demo version you downloaded from the net. See ``Download the
Necessary Files'' for details on acquiring the demo version.
Alternatively, if you've already got Quake installed on a Windows
machine, you can use the relevant files from that installation.
3.1. Prerequisites
You will need, as a bare minimum, the following:
· A Pentium 90 or better (133 recommended) computer
· 16 MB RAM (24 recommended)
· The Quake 2 CD-ROM or the demo version (q2-314-demo-x86.exe)
· Linux kernel version 2.0.24 or later
· libc 5.2.18 or later
· One of the following:
· X11 server that supports the MITSM shared memory extension. 8 and
16 bit displays are supported. (for X renderer)
· SVGAlib 1.2.10 or later (for SVGA and GL renderer)
· 25-400 megabytes free disk space (depending on how you install)
· Access to the root account of the machine you're installing on
Optional:
· A supported soundcard
· A 3Dfx Voodoo Graphics or Voodoo2 or Voodoo Rush 3D graphics
accelerator card.
· 3Dfx glide libraries installed (for GL renderer)
· Mesa 2.6 or later (for GL renderer)
3.2. Installing Quake II
3.2.1. Download the Necessary Files**
All the necessary files for Linux Quake II are available at id

3.2.2. Create the Installation Directory
The first thing you'll need to do is decide where you want to install
Quake II. Lots of folks like to put it in /usr/games/quake. Anal
system administrator that I am, I choose to install anything that's
not part of my Linux distribution under /usr/local. So for me, Quake
II goes in /usr/local/games/quake2. If you choose to install
somewhere else, please substitute the appropriate path wherever
/usr/local/games/quake2 is mentioned.
So go ahead and create the directory you'll install Quake II in, and
cd to it. The rest of these instructions will assume that this is
your current directory.
mkdir /usr/local/games/quake2
cd /usr/local/games/quake2
3.2.3. Installing from CD
Place your Quake II CD in your CD ROM drive, and mount it:
mount -t iso9660 /dev/cdrom /mnt/cdrom
If your CDROM is typically mounted elsewhere, substitute its location
for /mnt/cdrom. If you're not sure where your CDROM is mounted,
please see the documentation for your particular distribution.
· Full Install The simplest install method is a "full" install, which
involves copying the entire contents of your CD to your hard drive.
This requires about 350 MB, and is accomplished by issuing the
following commands:
cd /usr/local/games/quake2
cp -r /mnt/cdrom/Install/Data/* .
There'll be a bunch of unnecessary Windows files hanging around that
you can safely delete:
rm -f /usr/local/quake2/*.dll
rm -f /usr/local/quake2/quake2.exe
rm -f /usr/local/quake2/baseq2/gamex386.dll
· Medium Install If 450 MB is too much space for you to devote to
Quake II, you can skip installing the movie cutscenes and link to
them on the CD-ROM instead. This will reduce the space
requirements to about 200 MB:
cd /usr/local/games/quake2
mkdir baseq2
cp /mnt/cdrom/Install/Data/baseq2/pak0.pak baseq2
cp -r /mnt/cdrom/Install/Data/baseq2/players baseq2
ln -s /mnt/cdrom/Install/Data/baseq2/video baseq2/video
Note that this doesn't mean you have to mount your Quake II CD every
time to want to play Quake II. If the game can't load the videos, it
just won't display them.
3.2.4. Windows to Linux install
If you have Quake II installed under Windows on a different machine,
you can transfer the files in quake2\baseq2\ to your Linux system via
FTP or some other mechanism. Keep in mind that the filenames on your
Linux system must be in lower case for Quake II to find them, so you
may have to rename them after the transfer. Also note that it may be
necessary to delete your Windows installation after you do this to
remain in compliance with the terms of id's software license. It's
not my fault if you do something illegal.
If your Windows and Linux systems are on the same machine, you have
two options: copy the files from your Windows partition to your Linux
partition, or link to the necessary files from Linux. Both options
will work equally well. You'll just save a lot of disk space when you
link instead of copy. As usual, replace /win95/games/quake2 in the
following examples with the correct path to your Windows partition and
Quake II installation.
· If you want to copy the files from your Windows partition, do
something like this:
cd /usr/local/games/quake2
cp -r /win95/games/quake2/baseq2 .
· To create links to your Windows Quake II files instead, do this:
cd /usr/local/games/quake2
ln -s /win95/games/quake2/baseq2 .
This second method requires that the Windows partition you're linking
to be writeable by users, which may not be appropriate for all sys­
tems. By making your Windows partition writeable, you are giving all
users the opportunity to destroy your entire Windows installation. If
that's ok with you, modify your /etc/fstab to mount the Windows parti­
tion with the options umask=002,gid=XXX, where XXX is the group id
number of the "users" group. Look in /etc/group for this information.
When fstab is updated, umount and re-mount the Windows partition and
you're done.
You're done installing the Quake II data files. Move ahead to
"``Installing the Linux Binaries''".
3.2.5. Installing the demo version **
id Software has a freely available demo version of Quake II at their
ftp site. It's a 40 megabyte download. The demo includes all
features of the full version, including multiplayer, but it only comes
with three levels, so it may be difficult to find a server to play on.
See the section ``Download the Necessary Files'' above for the
location of the Quake II demo. Download it and place it in your Quake
II directory.
The demo distribution is a self-extracting zip file (it's self-
extracting in other OS's anyway). You can extract it with the
unzip(1) command, which should be included in most modern
distributions. If you don't have unzip, you can download it from the
location listed in the ``Download the Necessary Files'' section.
cd to your Quake II directory and extract the archive:
cd /usr/local/games/quake2
unzip q2-314-demo-x86.exe
Now we've got to delete some things and move some other things around:
rm -rf Splash Setup.exe
mv Install/Data/baseq2 .
mv Install/Data/DOCS docs
rm -rf Install
rm -f baseq2/gamex86.dll
The Quake II demo is now installed. You just need to add the Linux
binaries.
3.3. Adding the Linux Binaries**
There are four Linux Quake II packages available for download:
· a libc5 tar.gz package
· a glibc tar.gz package
· a libc5 rpm package
· a glibc rpm package
Install just one of these packages. Each contains the same files,
they're just linked against different libraries. Redhat 5.x users
should choose the the glibc rpm package. Users of glibc based systems
without rpm support should use the glibc tar package. The libc5 rpm
is for Redhat distributions prior to 5.0 and other distributions that
use the rpm package format. The libc5 tar.gz package is for Slackware
and everyone else.
See the ``Download the Necessary Files'' section for the location of
the Linux Quake II files.
3.3.1. Installing the RPM packages **
Installation of the rpm packages should be as simple as:
su root
rpm -Uvh quake2-xxxxx.i386.rpm
Rpm may complain that it can't find libglide2x.so. The Glide library
is only necessary if you have a 3Dfx card and want to run Quake II in
GL mode. If you don't plan to use the GL mode, you can override the
glide dependency with the --nodeps option:
su root
rpm -Uvh quake2-xxxxx.i386.rpm --nodeps
3.3.2. Installing the tar.gz packages **
To install, just untar the file in your Quake II directory. Do it as
root so the proper file permissions get set:
cd /usr/local/games/quake
su root
tar -xzf qwcl2.21-i386-unknown-linux2.0.tar.gz
3.4. Setting Permissions **
If you ran rpm or tar as root when installing the Quake II package on
your system, the file permissions should be properly set already. The
quake2 executable was installed setuid root so that it can access the
graphics devices on your system. For security, the ref_*.so rendering
libraries are owned by root and writeable only by him. If root
doesn't own the libraries, or they're world writeable, quake2 will
refuse to run.
If you plan to only run Quake II with the GL or X renderers, your
quake2 doesn't need to be setuid root. See ``Running X and GL games
without setuid'' in the Tips and Tricks section below for information
on running Quake II without root permissions.
3.4.1. Quake2.conf **
For security reasons, there is a quake2.conf file, which tells Quake
II where to find the rendering libraries it needs (ref_*.so). It
contains only one line, which should be the path to your Quake II
installation. Quake II looks for this file in /etc. If you installed
Quake II from an .rpm file, this file was installed for you. If you
installed from a .tar package, you need to create it like so:
su root
cd /usr/local/games/quake2
pwd > /etc/quake2.conf
chmod 644 /etc/quake2.conf
3.5. The X Renderer
Quake II should be ready to run under X now. Give it a try:
cd /usr/local/games/quake2
./quake2 +set vid_ref softx
If all is well, after a pretty significant pause, a small Quake II
window will appear with the first demo running in it. You should hear
sound effects and possibly music, if the CD is mounted. If any of
this fails to occur, please see section ``Troubleshooting'' for help.
3.6. The SVGAlib Renderer
You need SVGAlib installed and configured if you're going to use
either the ref_soft or ref_gl renderers. (Quake II uses SVGAlib to
process keyboard and mouse input, in case you're wondering why you'd
need it for the GL renderer). SVGAlib comes with most modern
distributions, and must be properly configured before Quake II will
run correctly outside of X.
libvga.config is SVGAlib's configuration file. On most systems you'll
find it in either /etc or /etc/vga. Make sure the mouse, monitor, and
video card settings in this file are correct for your system. See the
SVGAlib documentation for more details.
If you don't already have SVGAlib on your system, download it from the
location mentioned in ``the files section'' above. If you have a
RedHat 5.x or other glibc-based Linux distribution, see ``Glibc,
RedHat 5.x, Debian 2 considerations'' in the Troubleshooting/FAQs
section for important information about compiling libraries for Quake
II. A precompiled libc5 SVGAlib binary is available at
http://sunsite.unc.edu/pub/Linux/libs/graphics/svgalib-1.3.0.libc5.bin.tar.gz
for those who don't want to deal with the hassle of compiling for
libc5.
You should run Quake II from a virtual console when using the ref_soft
or ref_gl renderers. It won't run from X unless you're root when you
start it, and that's not advisable. So if you're in X, do a
CTRL+ALT+F1, login and then:
cd /usr/local/games/quake2
./quake2
``Running SVGA and GL games from X'' in the Tips & Tricks section
below explains how to launch SVGA and GL Quake II from X without
manually switching to a virtual console.
3.7. The OpenGL Renderer
Hardware-accelerated OpenGL Quake is Quake the way God intended it to
be. There is no substitute, and once you've experienced it there's no
going back.
To run Quake II in GL mode, you need a 3D card with the Voodoo,
Voodoo2 or Voodoo Rush graphics chipset on it. There are specific
issues to be dealt with if you have a Voodoo Rush card, and I won't go
into them now because frankly, I wouldn't know what I was talking
about. A future version of this HOWTO will cover Rush issues (If
somebody wants to write about Voodoo Rush issues, I'll gladly include
it here).
The SVGAlib, Glide, and Mesa libraries must all be installed and
configured properly on your system for quake2 to work. The following
sections will very briefly cover what you need to do to get them
going.
Bernd Kreimeier's (bk@gamers.org) Linux 3Dfx HOWTO
(http://www.gamers.org/dEngine/xf3D/howto/3Dfx-HOWTO.html) is good
source for further information.
The 3dfx.glide.linux newsgroup on the 3dfx news server (news.3dfx.com)
is another good source of information about the intersection of Linux,
glide, Mesa and Quake.
3.7.1. SVGAlib
Quake II uses SVGAlib to get input from the mouse and keyboard, so
you'll need to configure it as outlined in section ``SVGAlib
Renderer'' section.
3.7.2. Glide
Glide is a library that provides an API for programming 3Dfx based
cards. If you want the Mesa graphics library to use your 3Dfx card,
you've gotta have it.
The latest version of glide can always be found at
http://glide.xxedgexx.com/3DfxRPMS.html. Select the package(s)
appropriate for your system, and install according to the instructions
on the web page.
Note that unless you download the 3Dfx device driver package in
addition to the Glide library, you will only be able to run Glide
applications (like GLQuake) as root. Install the /dev/3dfx module and
you can play GLQuake as a regular user.
Once you have glide installed, try out the test program that comes
with it. Remember this program: it's a good way to reset your
display if you ever have a glide application (like GLQuake) crash and
leave your screen switched off. NOTE: run this test from a VC, not X!
It's possible for the test app to lose mouse and keyboard focus in X,
and then you'll have no way of shutting it down.
/usr/local/glide/bin/test3Dfx
Your screen should turn blue and prompt you to hit any key. After you
press a key you should be returned to the prompt. 3dfx.glide.linux on
3dfx's news server (news.3dfx.com) is a great source of information
for Linux glide-specific problems.
3.7.3. Mesa
Once glide's installed, you need to install Mesa, a free OpenGL
implementation by Brian Paul (brianp@elastic.avid.com). Luckily, you
won't have to look far, because Mesa 2.6 is included with the Quake II
binaries. All you have to do is move it to the right place:
cd /usr/local/games/quake2
cp libMesaGL.so.2.6 /usr/local/lib
ldconfig
If you want to upgrade Mesa to a more recent version (Mesa 3.0 is the
most recent version as of this writing), you can download the latest
from ftp://iris.ssec.wisc.edu/pub/Mesa If you have a RedHat 5.x or
other glibc-based Linux distribution, see ``Glibc, RedHat 5.x, Debian
2 considerations'' in the Troubleshooting/FAQs section for important
information about compiling libraries for Quake.
After you've built it according to the instructions, you will have to
do two things:
· Remove your old Mesa installation. If you previously installed a
libMesaGL.so.2.6 as described above, you must remove it or Quake II
may not use the new version.
cd /usr/local/lib/
rm -f libMesaGL.so.2*
· If the new Mesa has a major version number that's greater than 2,
you need to create a link to it with the name libMesaGL.so.2:
cd /usr/local/lib/
ln -s /wherever/you/installed/it/libMesaGL.so.3.0 libMesaGL.so.2
ldconfig
Now switch to a VC (CTRL+ALT+F1) and start Quake II:
cd /usr/local/games/quake2
./quake2 +set vid_ref gl
3.7.4. lib3dfxgl.so **
With Quake II version 3.19, an alternative to the Mesa library is
available. lib3dfxgl.so is a mini-GL driver optimized for Quake that
provides slightly better framerates than Mesa. This is a port of a
driver that 3Dfx developed for Quake under Windows, and apparently not
all of its features work properly yet. So hopefully we can expect its
performance to improve with time.
Like Mesa, lib3dfxgl.so requires Glide in order to access your 3Dfx
card. The Quake II packages come with a script, quake2.3dfxgl for
running Quake II with this library on glibc systems. The next
paragraph explains how to run Quake II with lib3dfxgl.so on a libc5
system. On a glibc system, the glqwcl executable must not be setuid,
nor should you run it as root. glqwcl will silently load Mesa rather
than lib3dfxgl.so if it runs with root permissions. This non-root
requirement implies that you have the /dev/3dfx driver installed.
On a libc5 system, the non-root requirements mentioned above apply,
but you also need to create a symbolic link to lib3dfxgl.so called
libMesaGL.so.2 like so:
cd /usr/local/games/quake2
ln -sf lib3dfxgl.so libMesaGL.so.2
Then start Quake II from a script that tells $LD_LIBRARY_PATH to look
in the current directory:
______________________________________________________________________
#!/bin/sh
LD_LIBRARY_PATH=".:$LD_LIBRARY_PATH" ./quake2 +set vid_ref gl $*
______________________________________________________________________
You can tell which driver is being loaded by looking for output like
the following in your console as Quake II starts:
GL_VENDOR: 3Dfx Interactive Inc.
GL_RENDERER: 3Dfx Interactive Voodoo^2(tm)
GL_VERSION: 1.1
GL_EXTENSIONS: 3DFX_set_global_palette WGL_EXT_swap_control GL_EXT_paletted_texture GL_EXT_shared_texture_palette GL_SGIS_multitexture
If GL_VENDOR says Brian Paul rather than 3Dfx Interactive Inc., that
means Mesa is still being used rather than the miniport dirver.
3.8. The GLX Renderer **
ref_glx.so is linked against standard OpenGL libraries instead of
Mesa. This allows Quake II to run on other 3D hardware that is
supported by other OpenGL implementations. At this time, I dont' know
of any OpenGL implementations that support hardware other than 3Dfx,
but this renderer ensures that when they appear, we'll be able to play
Quake II with them.
This is a GLX application, and as such, must be run from X.
You can use this client with Mesa/3Dfx if you install Mesa and Glide
as explained in the previous section, then set the $MESA_GLX_FX
environment variable to "fullscreen" before you run quake2:
export MESA_GLX_FX=fullscreen
./quake2 +set vid_ref glx +set _windowed_mouse 1
Why the +set _windowed_mouse 1 option? Remember that this is an X
application which happens to use your 3Dfx card. Even though the
display takes up your entire screen, Quake II is stil running in a
window. This means that if you're not very careful, you could move
the mouse pointer outside the Quake II window, and Quake II will
suddenly stop responding to mouse and keyboard input. +set
_windowed_mouse 1 avoids this problem by telling quake2 to grab the
mouse and not let it move outside its window.
3.9. Linux-Specific Command Line Options
This section will cover command line options that are specific to the
Linux version of Quake II. There are plenty of other Quake II
options, but they're beyond the scope of this HOWTO. Check out some
of the sites listed in section ``General Quake Information'' for this
kind of information.
These are actually cvars (client variables) that you can set in the Q2
console, but it makes the most sense to set them on the command line.
Set them with +set on the command line, like:
./quake2 +set cd_dev /dev/hdc
cd_dev device
Name of the CD-ROM device.
nocdaudio value
Disable CD audio if value is nonzero
sndbits num
Set sound bit sample size. Default is 16.
sndspeed num
Set sound sample speed. Usual values are 8000, 11025, 22051 and
44100. If set to zero, causes the sound driver to attempt
speeds in the following order: 11025, 22051, 44100, 8000.
sndchannels num
Indicates stereo or mono sound. Defaults to 2 (stereo). Use 1
for mono.
nostdout value
Don't do any output to stdout. Use this if you don't want all
the console output dumped to your terminal.
3.10. Quake II Servers
Linux's strength as an internet server make it a perfect platform for
running an internet Quake II server. This section will touch on the
basics and Linux-specific aspects of starting up a Quake II server.
More detailed information about running Quake II servers is available
elsewhere (see section ``Other Sources of Information'' earlier in
this document.
3.10.1. Listen Servers
You can start a Quake II "Listen" server from within the game via the
Multiplayer menu. This allows you to host a game and participate in
it at the same time.
To start a Listen server, start Quake II, bring up the Quake II menu
with the ESC key, and select Multiplayer. It should be pretty self-
explanatory from there.
3.10.2. Dedicated Servers
For a permanent, stand-alone Quake II server that needs to run without
constant attention, using the Listen server is impractical. Quake II
has a Dedicated server mode that is better suited to this type of use.
A dedicated server is started from the command line and uses fewer
system resources than a Listen server because it doesn't start the
graphical client piece at all.
To start a dedicated server, use the command line option +set
dedicated 1. You can set additional server parameters either on the
command line or in a config file that you +exec on the command line.
Your config file should reside in the baseq2 directory.
A few common server options are listed below. To set options on the
command line, do +set fraglimit 30. Options are set the same way in a
config file, only you don't want the + before the set. Invoke your
config file like this: +exec server.cfg.
fraglimit
Number of frags required before the map changes
timelimit
Time in minutes that must pass before the map changes
hostname
The name of your Quake II server. This is an arbitrary string
and has nothing to do with your DNS hostname.
maxclients
The maximum number of players that can connect to the server at
once.
For enough Quake II console and command line information to choke a
horse, see Farenheit 176 (http://www.planetquake.com/f176).
3.10.3. Other Sources of Server Information
· The Q2 Server FAQ has a basic step-by-step guide to set up a Q2
Server under Linux: http://www.bluesnews.com/faqs/q2s-faq.html
· Grant Cornelius Reticulus Copernicus Sperry (flubber@xmission.com)
has some basic Q2 server config files and startup scripts at
http://www.atomicage.com:80/quake/server/server_cfg/.
3.11. Mods & Addons
Quake II modifications like Capture the Flag, Jailbreak, and Lithium
II are very popular extensions of the original Quake II game. Some
mods reside entirely on the server (Lithium), and some also require
changes to your client (CTF). For server only mods, you just connect
normally and play. Client-side mods require you to install additional
files in your quake2 directory before you can play.
3.11.1. Client Side Mods
Generally, installation of a client-side mod consists of just
downloading the client package and upacking it in your Quake II
directory, but you should refer to the mod's documentation for
specific details. It may be necessary to download a Linux-specific
package in addition to the main (Windows) client package. Also be
aware that all mods may not be available for Linux.
Client-side mod packages usually contain a new gamei386.so file and
one or more .pak files. Other new files may be included as well.
These new files will be installed in a subdirectory below your Quake
II directory. Use +set game mod-dir on the command line to run the
mod. Rocket Arena 2, for example, gets installed in a directory
called arena. To play RA2, your would start your client like so:
./quake2 +set game arena
3.11.1.1. Capture the Flag
Since this is by far the most popular variation of multiplayer Quake
II, I've included specific instructions for installing this mod.
Capture the Flag for Quake II is available from id's ftp site.
Download it, then install like so:
cd /usr/local/games/quake2
mkdir ctf
cd ctf
unzip -L /wherever/you/put/it/q2ctf102.zip
Start Quake II with +set game ctf to play CTF.
3.11.2. Server Side Mods
Running a Quake II mod on a server isn't much different than running
one on the client side. Generally you'll need to install gamei386.so
and server.cfg files in a new subdirectory and then start your server
like
./quake2 +set game XXXX +set dedicated 1 +exec server.cfg
Where XXXX above is the name of the mod's new subdirectory. The exact
procedure will vary from mod to mod, of course. See the mod's docu­
mentation for specific details.
3.11.3. Game Source
The entire game, with the exception of the engine itself, resides in a
shared library, gamei386.so. Quake II mods are created by changing
the contents of this file. The C source is freely available (section
``Download the Necessary Files'' above) for anyone to download and
modify.
After you've downloaded the source, here's how to get started with it:
cd /usr/local/games/quake2
mkdir mymod
cd mymod
gunzip /wherever/you/put/it/q2source-3.14.shar.Z
sh /wherever/you/put/it/q2source-3.14.shar
You'll be presented with a bunch of legalese that you must answer yes
to, then the game source will be extracted. Building a new
gamei386.so out of these sources is accomplished with a simple make.
You can run Quake II with the newly compiled library like so:
cd /usr/local/games/quake2
./quake2 +set game mymod
Not too exciting yet, since what you just built is identical to the
"stock" gamei386.so, but this should be good information for aspiring
mod authors.
3.11.4. Mission Packs **
· Mission Pack 1: The Reckoning The Reckoning requires Quake II
version 3.15 or later to run. You'll need at least 95 MB for a
minimum installation. Another 90 MB are required if you want to
install the video sequences as well. Assuming your CD is mounted
on /mnt/cdrom and Quake II is installed in /usr/local/games/quake2:
cd /usr/local/games/quake2
cp -r /mnt/cdrom/Data/all/* xatrix/
rm -f xatrix/gamex86.dll
If you want to install the video sequences:
cp -r /mnt/cdrom/Data/max/xatrix/video xatrix
Play The Reckoning like this:
cd /usr/local/games/quake2
./quake2 +set game xatrix
· Mission Pack 2: Ground Zero It requires Quake II version 3.17 or
later to run. You'll need at least 120 MB for a minimum
installation. Another 115 MB are required if you want to install
the video sequences as well. Assuming your CD is mounted on
/mnt/cdrom and Quake II is installed in /usr/local/games/quake2:
cd /usr/local/games/quake2
cp -r /mnt/cdrom/Data/all/* rogue/
rm -f rogue/gamex86.dll
If you want to install the video sequences:
cp -r /mnt/cdrom/Data/max/rogue/video rogue
Play Ground Zero like this:
cd /usr/local/games/quake2
./quake2 +set game rogue

4.1. QStat
Qstat is a command line based program that returns the status of
internet Quake, QuakeWorld, and Quake 2 servers created by Steve
Jankowski mailto:steve@activesw.com.
Here's the feature summary from the QStat homepage:
· Supports Windows 95, NT, and most Unixes
· Comes with C source code and a binary for Windows
· Supports old Quake (NetQuake), QuakeWorld, Hexen II, and Quake II
servers
· Can display all available statistics, including player info and
server rules
· Output templates for automatic HTML generation
· Raw display mode for integration with HTML page generators
· Built-in host name cache
· Sort by ping time, game, or both
· More options than you can wiggle a mouse at
Qstat is a must-have tool if you're planning on doing any net play. A
number of front-ends for qstat have been written as well. Some of
them are listed later in this section.
You can get the latest version of qstat from the QStat Homepage
(http://www.activesw.com/people/steve/qstat.html.
4.2. XQF
XQF is a graphical front-end to QStat that uses the GTK toolkit. This
is the best QuakeWorld/Quake2 server browser that currently exists,
and Roman Pozlevich (roma@botik.ru), is still cranking out revisions
at the rate of about one per month.
If you're familiar with GameSpy for the Windows platform, this is the
closest thing to it for Linux.
The XQF homepage is at http://www.linuxgames.com/xqf.
4.3. QuickSpy
QuickSpy is a text-based QuakeWorld server browser. It's another
front-end to QStat and it works pretty well. If you don't run X and
you don't have Quake II, this is a decent option. Beware though, it's
no longer under development.
You can get QuickSpy at
http://diana.ecs.soton.ac.uk/~rht96r/quake/quickspy/.
4.4. QPlug for Linux
Qplug is a Netscape plugin which retrieves and displays QuakeWorld and
Quake II server information embedded in a web page. A Windows Qplug
has been around for some time. The author, Olivier Debon
(odebon@club-internet.fr) wrote the Linux version from scratch without
ever having seen the Windows version.
QPlug for Linux can be got at
http://www.geocities.com/TimesSquare/Labyrinth/5084/qplug.html.
4.5. qkHacklib
David Bucciarelli (tech.hmw@plus.it), author of the 3Dfx driver for
Mesa, has written a library called qkHack, which tries to emulate all
the SVGAlib/fxMesa functions used by Quake and Quake II. This would
remove the need for SVGAlib when running glquake or Quake II with
ref_gl. Other features from the qkHacklib README:
· You can dynamically switch between fullscreen rendering and the in
window rendering just pressing the TAB key (you must start your X
server in 16 bpp mode in order to use this feature)
· You can press Ctrl-C in the shell or kill the Quake process without
problems
· you can enable/disable the mouse and keyboard 'grabbing' pressing
F11/F12
· you can iconify and pause Quake pressing the F10 (it will not eat
more CPU cycles). You can restart everything with a double click in
the "****" icon
· you can run Quake with any Mesa driver (for example with the X11
driver but you must recompile the Mesa without the Voodoo driver)
· you can run Quake under any Linux box and get the hardware
acclerated output on a SGI box (OK, this is a bit exotic and
theoretical as feature but it is an example of how powerful can be
an GLX/OpenGL application)
I've tried qkHacklib and it works great for Quake on my system. In
Quake II, however, the mouse response becomes really slow. Others
report complete success, though, so give it a try it it sounds like
something you need.
David Bucciarelli's qkHacklib web page is at http://www-
hmw.caribel.pisa.it/fxmesa/fxqkhack.html.
4.6. GiMd2Viewer
GiMd2Viewer is a Quake 2 model viewer written for Gtk and OpenGL by
Lionel Ulmer (bbrox@mygale.org). It loads models and textures from
either plain files or .PAK files. It will also animate the models
(with frame interpolation).
This program is still under developement and I haven't tried it yet,
but it sounds pretty nifty. Check it out at
http://www.mygale.org/~bbrox/GiMd2Viewer/.
4.7. QIPX
QIPX is a set of programs that allow Linux Quake clients (using
TCP/IP) to connect with DOS Quake clients (using IPX). I guess this
is useful if you're playing netquake on a LAN. QIPX is available at
http://www.geocities.com/SiliconValley/Park/6083/qipx.html.
4.8. Ice
Ice is a Quake map editor for UN*X created by C.J. Beyer and John
Watson. I haven't used this program, nor do I know what its
development status is. The Ice homepage is at
http://styx.phy.vanderbilt.edu/~ice/.
4.9. Q2getty
Q2getty is a hack of mingetty by Mike Gleason (mgleason@ncftp.com)
that allows you to automatically run and respawn a program (like a
Quake server) on a virtual console. This program is available in the
files section at http://www.ncftpd.com/unixstuff/q2getty.html.
4.10. rcon
Rcon is a pair of tools that allow remote administration of a Quake II
server using the RCON protocol. Michael Dwyer
(michael_dwyer@mwiworks.com) is the author. Rcon 1.1 is available at
.
4.11. qlog ++
Qlog is a GPL'ed QuakeWorld/Quake II server log parser that generates
comprehensive player statistics. Craig Knudsen (cknudsen@radix.net)
is the author. The qlog homepage is
http://www.radix.net/~cknudsen/qlog/.
4.12. Cheapo **
Cheapo is a proxy that can be used to route QuakeWorld network
traffic. Additionally, the proxy can modify the data and has features
for enhancing gameplay. You can connect to cheapo as if it were a
Quakeworld server, and then give it commands that forward you to a
real server. The proxy can also be run on a firewall machine
incapable of handling Quake traffic, so that machines inside the
firewall can be used for playing. The Cheapo homepage is at
http://www.saunalahti.fi/~softech/.
4.13. qgraph **
QGraph (Quake Graph) is a utility to help people in managing Quake's
DeathMathes, turnments and Quakeworld games. QGraph is a program who
connects (via Lan or the Internet) to a Quake, QuakeII, Quakeworld and
Hexen2 Servers and shows you realtime data about the game running on
that server. The QGraph homepage is at http://www.frag.com/qgraph.
5. Troubleshooting/FAQs
5.1. General
5.1.1. OS difference considerations
· Case sensitivity - In DOS and Windows, case is not important.
BASE1.TXT is the same as base1.txt. Under Linux and other unices,
case IS significant. MOTD.TXT and motd.txt are different files.
This can cause problems with player models and skin files if
they're installed with upper- or mixed-case filenames.
players/male/santa.PCX needs to be renamed to santa.pcx in order to
work in Linux. The fixskins.sh script included with quakeworld
will convert all filenames in a directory to lowercase. It's
reproduced below for your convenience:
___________________________________________________________________
#!/bin/sh
for x in *; do
y=`echo $x | tr '[A-Z]' '[a-z]'`
if [ $x != $y ]; then
mv $x $y
fi
done
___________________________________________________________________
· Path delimiters - DOS and Windows use the backslash "\" character
to separate file pathname elements. In Unix, the backslash is an
escape character. If you use file pathnames in your config files
(or your mod code, or anywhere else, for that matter), be sure
you're using "/" and not "\".
· End of line characters - Under DOS/Windows, each line of a text
file ends with a carriage return character (CR) and a linefeed
character (LF). Unix textfiles just have a linefeed at the end of
each line. Using DOS/Win formatted textfiles in Unix can cause all
kinds of mysterious Quake problems. Using the incorrectly
formatted quake2.conf file from the Quake2 3.17 package, for
example, gives the error "LoadLibrary("ref_XXX.so") failed: No such
file or directory". LMCTF-TE reports a floating point exception.
If you've got an problem you can't explain, try removing the CRs
from your text files:
mv file.txt file.bak; tr -d '\r' < file.bak > file.txt
5.1.2. Glibc, RedHat 5.x, Debian 2 considerations**
The following applies the Quake I binaries (squake, glquake, and
quake.x11) only. As of versions 2.30 and 3.19 respectively,
QuakeWorld and Quake II are available in both libc5 and glibc
versions.
The Quake executables were compiled with libc5. Newer Linux
distributions like RedHat 5.1 and Debian 2.0 use the incompatible
glibc as their default C library. If you're running Quake on a glibc
system, there are a few things to watch out for:
· Both RedHat 5 and Debian 2 have libc5 compatibility packages that
allow you to run libc5-based applications. Make sure you have
these packages installed. Both distributions put the libc5-based
libraries in /usr/i486-linux-libc5/lib.
· Make sure Quake uses the correct libraries. Create a script like
the one below that points $LD_LIBRARY_PATH to your compatibility
libraries directory before it runs Quake.
___________________________________________________________________
#!/bin/sh
export LD_LIBRARY_PATH=/usr/i486-linux-libc5/lib
./quake2 +set vid_ref gl $*
___________________________________________________________________
· If you are going to compile a library like SVGAlib or Mesa for use
with Quake, it must be compiled with libc5 and friends. Simply
building a new library according its installation instructions will
result in a library that is linked against your default library,
glibc. You must ensure your new library is linked only with libc5
and libc5-based libraries so it will be compatible with Quake. See
your distribution's documentation for information on linking to the
non-default libraries.
5.1.3. My mouse doesn't work or seems to respond randomly.
· Is gpm running? gpm is a program that enables you to cut and paste
with the mouse in virtual consoles. Many distributions enable it
by default. It may be interfering with Quake. Check if it's
running with the following command:
ps aux | grep gpm
If you get output like
root 6115 0.0 0.4 832 316 ? S 17:54 0:00 gpm -t PS/2
then gpm is running and interfering with Quake. gpm -k (as root)
ought to stop gpm. If it doesn't (gpm -k doesn't always work on my
system), kill gpm with the command killall gpm.
If you never use gpm, you may want to stop it from running at startup.
See the documentation for your distribution for information on how to
do this.
· Is your mouse defined properly in libvga.config? This file usually
lives in /etc or /etc/vga. Open it up and look for a line like
mouse Microsoft
On my system, this is the first option in the file. Make sure the
mouse type is appropriate for your hardware.
5.1.4. My Microsoft Intellimouse or Logitech MouseMan+ isn't working
correctly.
SVGAlib, which handles mouse input for SVGA and GL Quake/QW/Q2, didn't
directly support the Intellimouse until version 1.3.0. If you have a
version of SVGAlib prior to 1.3.0, you should upgrade, then use mouse
type IntelliMouse (for serial mice) or IMPS2 (for PS/2 mice) in your
libvga.config file.
5.1.5. My mouse is "laggy" and seems much slower than under Windows.
· For many people, just cranking up the value of sensitivity in the
game console cures the problem. Setting sensitivity by hand in the
console or in a .cfg file allows you to increase the mouse
sensitivity more than the slider in the Options menu. sensitivity
15, for example.
· From Zoid's 1/7/98 .plan update:
If you are experience video 'lag' in the GL renderer (the
frame rate feels like it's lagging behind your mouse move&SHY;
ment) type "gl_finish 1" in the console. This forces update
on a per frame basis.
· The latest version of SVGAlib (1.3.0) provides a slew of parameters
in libvga.config that you can use to customize the behavior of your
mouse. With the proper settings it should be possible to make your
mouse feel any way you want. On my system, just changing
mouse_accel_type to normal (default is power) gave me the results I
wanted. I haven't messed with the other settings, and I don't
pretend to have a clue about what they all do.
· The little slider
5.1.6. I have a Voodoo2, and, when I try to run with the gl renderer,
it reports that I don't have a Voodoo card installed.
There are different versions of Glide for Voodoo and Voodoo 2 cards.
Be sure you downloaded the correct one for your system.
5.1.7. When I'm playing any of the Quake games under SVGAlib or GL
and press CTRL-C, the game exits and sometimes leaves my console in an
unusable state.
5.1.8. Sometimes when Quake/Quake II exits abnormally, it leaves my
console unusable.
Yes. This bites. SVGAlib catches the CTRL-C and decides what to do
with it instead of allowing Quake to handle it. I know of no way
around this short of hacking SVGAlib.
If you run your Quake games from a script that resets the keyboard and
terminal like the one below, you'll run less chance of ending up with
a hosed terminal if this does happen, though.
______________________________________________________________________
#!/bin/sh
./quake2 $*
kbd_mode -a
reset
______________________________________________________________________
5.1.9. squake/quake2 fails to start and says " svgalib: cannot get
I/O permissions"
The Quake executables must run as root, so you must either run them as
root or make them setuid root. See the installation instructions in
this document for details.
5.1.10. Sometimes after playing one of the Quake games in X, key
repeat doesn't work any more.
For some reason, the X11 versions of Quake disable key repeat while
they're running. If the program exits abnormally for some reason, key
repeat never get turned back on. Do
xset r on
to reenable it.
5.1.11. Quake/Quake II says "/dev/dsp : device not configured"
Your sound hardware is not properly configured. You may simply need
to do a insmod sound, or it may be necessary to rebuild your kernel.
RedHat users may need to invoke the sndconfig(8) utility. See the
documentation for your Linux distribution and/or the Linux Sound HOWTO
for information on configuring your system's sound hardware.
5.1.12. GL Quake/Quake II run slower in Linux than in Windows. **
The Windows 3Dfx GL miniport is heavily optimized for the things Quake
II does. Mesa on the other hand, is more general and less optimized
As a result, Linux Quake II runs slower than under Windows. This
isn't a limitation of Linux, but a limitation of the current drivers.
With the most recent releases of QuakeWorld and Quake II, the 3Dfx
miniport mentioned above is available for Linux. While it still
doesn't bring Linux Quake performance to par with Windows Quake, it's
another step in that direction.
Additionally, for Pentium Pro and Pentium II users, there are some
tweaks than can be done with memory buffering - the latest /dev/3dfx
device driver has support for automatically setting this up for you.
Enabling MTRRs can result in significant (10 fps on my system) GL
Quake speedups. See http://glide.xxedgexx.com/MTRR.html for some more
detailed information about this.
5.1.13. How can I start a server and log off, then come back to it
later? **
screen(1) is a great utility for this sort of thing. It allows you to
create many virtual screens in one tty and switch between them.
Screen comes with most distributions. You can download it from
ftp://prep.ai.mit.edu/pub/gnu or any GNU mirror.
Start screen by typing the command screen, then create a new screen
window by pressing CTRL-A CTRL-C. You won't see much as you do these
things, but be assured, something is happening.
Start a Quakeworld server:
/usr/local/games/quake/qwsv
Now open a new screen window with CTRL-A CTRL-C and start up a Quake
II server:
/usr/local/games/quake2/quake2 +set dedicated 1
You can switch back and forth between your servers by pressing CTRL-A
CTRL-N.
Press CTRL-A CTRL-D to detach from the screen program. Screen and
your servers are still running, but they're no longer visible in your
terminal window. You can logoff now and your processes will continue
to run normally.
Use screen -r to re-attach to your previous screen process and access
your servers again.
That's all there is to it. See the screen(1) man page for more
detailed information.
5.2. Quake/QuakeWorld
5.2.1. Quake dies at startup with a segmentation fault.
This usually means your network setup isn't right. Try starting quake
with the -noudp option and see if the error goes away. If that fixes
it, check your /etc/hosts file and verify there's an entry for your
machine in it. Use 127.0.0.1 for your IP address if you have a dialup
account that gives you a different address each time you connect.
5.2.2. What's the difference between glqwcl , glqwcl.3dfxgl , and
glqwcl.glx ? ++
· glqwcl is the standard GL Quakeworld client you've seen in previous
versions. It's linked against libMesaGL.so.2.
· glqwcl.3dfxgl is a script that runs glqwcl after preloading the
3Dfx GL miniport library, lib3dfxgl.so. Preloading the minport
library causes its GL functions to get used instead of Mesa's.
Since the GL minport is optimized for Quake, this is a good thing.
· glqwcl.glx is linked against standard OpenGL libriaries instead of
Mesa. This will allow glquake to run on other 3D hardware that is
supported by some other OpenGL implementation. This is an X
application and so must be run from X.
5.2.3. When I run glqwcl.glx fullscreen from X, I can't use my mouse
or keyboard. ++
Run glqwcl.glx with the +_windowed_mouse 1 option. GLX Quakeworld is
running in a window, even though it appears to take up your whole
screen. If you move the mouse while the WM is in focus-follows-mouse
mode, you're likely to move the pointer outside this window, and then
Quake will stop responding to mouse and keyboard input.
+_windowed_mouse 1 makes Quakeworld grab the mouse exclusively.
5.3. Quake II
5.3.1. When I try to run Quake II with the GL renderer, it fails and
says "LoadLibrary("ref_gl.so") failed: Unable to resolve symbol"
If immediately prior to the "Unable to resolve symbol" line, you have
messages like "can't resolve symbol 'fxMesaCreateContext'", your Mesa
library doesn't have glide support compiled in. See section ``The GL
renderer'' in the Quake II installation section for information on
installing Mesa and glide.
5.3.2. Quake II fails with the message LoadLibrary("ref_XXX.so")
failed: No such file or directory
· /etc/quake2.conf doesn't have the correct path to your Quake II
directory in it. This file should contain one line that is the
directory Quake II lives in.
· If /etc/quake2.conf does contain the correct path, try removing the
file and re-creating it by hand. Some versions of Quake II for
Linux included an incorrectly formatted quake2.conf file.
· Do you have SVGAlib installed? Check /lib, /usr/lib and
/usr/local/lib for a file called libvga.so.1.X.X, where the X's are
some numbers. If nothing turns up, you need to get and install
SVGAlib to run Quake II outside of X.
· If the renderer in question is ref_gl.so, Mesa may not be properly
installed. Did you copy libMesaGL.so.2.6 to a library directory
like the installation instruactions told you to?
· If the renderer in question is ref_gl.so, did you install the glide
libraries?
5.3.3. When I update the brightness while using the GL renderer, and
hit "apply," nothing happens!
Type vid_restart in the console to make the changes take affect.
5.3.4. Note about the 3.17 distribution
As of this writing, the most recent Quake II version is 3.19. If for
some reason, you're running version 3.17 instead, the following
information may be helpful to you.
Two text files (quake2.conf and fixperms.sh) in the 3.17 distribution
were inadvertently saved in MS-DOS CR/LF text-file format instead of
the unix LF format. This means there's an extra carriage return
character at the end of each line in these files and they're not going
to behave right until you fix them.
We'll run them through tr(1) to strip out the CR's.
for i in fixperms.sh quake2.conf
do
mv $i $i.bak
tr -d '\r' < $i.bak > $i
done
5.3.5. When I run Quake II with +set vid_ref glx fullscreen from X,
I can't use my mouse or keyboard. ++
Run GLX quake2 with the +set _windowed_mouse 1 option. GLX Quake2 is
running in a window, even though it appears to take up your whole
screen. If you move the mouse while the WM is in focus-follows-mouse
mode, you're likely to move the pointer outside this window, and then
Quake II will stop responding to mouse and keyboard input. +set
_windowed_mouse 1 makes Quake II grab the mouse exclusively.
5.3.6. Why can't I change to some of the SVGA modes that aree in the
Quake II Video menu? **
SVGAlib probably doesn't know how to create the modes on your card.
When Quake II starts up with the SVGA renderer (ref_soft.so), it
prints a list of all the modes that SVGAlib tells it are available:
------- Loading ref_soft.so -------
Using RIVA 128 driver, 4096KB.
mode 320: 200 1075253220
mode 320: 240 1075253220
mode 320: 400 1075253220
mode 360: 480 1075253220
mode 640: 480 1075253220
mode 800: 600 1075253220
mode 1024: 768 1075253220
mode 1280: 1024 1075253220
These are the only modes you will be able to successfully switch to
from the Video menu. If say, 512x384 isn't on the list, selecting it
from the Video menu won't work.
SVGAlib does let you define new video modes for some chipsets in
libvga.config, so you may be able create your own video mode this way.
See the SVGAlib documentation for more detail on this topic.
6. Tips & Tricks
6.1. Running X and GL games without setuid
If you only run the X and GL versions of Quake, QuakeWorld or Quake
II, you don't need to run them with root permissions. SVGA is the
only mode that must be run as root. The X versions just need access
to /dev/dsp, the sound device. The GL versions need access to the
3Dfx card as well as to /dev/dsp.
/dev/dsp needs to be readable and writeable by Quake. Most
distributions give it 662 (rw-rw--w-) permissions by default. The
simplest solution is to just chmod 666 /dev/dsp. On most systems, the
ability to read from the sound device will not pose a significant
security threat. If this approach is unacceptable for your system,
create a group that owns /dev/dsp and make your Quake players members
of that group.
You need the /dev/3dfx driver from Daryll Strauss' glide page
(http://glide.xxedgexx.com/3DfxRPMS.html) in order run glide
applications (like GLQuake) non-root. Download the Device3Dfx.xxx.rpm
package and install according to the instructions on the web page.
After you've installed the driver, make sure /dev/3dfx has 666
permissions (chmod 666 /dev/3dfx).
When /dev/dsp and /dev/3dfx are properly set up, you can remove the
setuid bit from your Quake/QW/Q2 executables. Just do (as root) chmod
0755 XXXXX, where XXXXX is either glquake, quake.x11, or quake2.
If you've been playing as root prior to making these changes, many of
your Quake files (like savegames) may be owned by root and
inaccessible to a normal user, so remember to change the files'
ownership before you attempt to play the game non-root.
6.2. Running SVGA and GL games from X**
The GLX Quakeworld and Quake II clients are native X applications, but
since they use Mesa rather than the 3Dfx mini-driver, they're slower
than the lib3dfxgl.so versions. For this reason, you may still favor
this way of starting games from X over using the GLX clients.
This is based on a Linux Gazette 2 Cent Tip by Joey Hess
(joey@kite.ml.org) The original is at
http://www.ssc.com/lg/issue20/lg_tips20.html#squake
Yes, it's possible to run the Quake games from X if you're root, but
such behavior is naughty, and you still run the risk of having Quake
crash and leave the console unresponsive. With a little work you can
make it possible for a regular user to run SVGA and GL Quake from X
AND automatically switch back to X when the program is finished,
regardless of whether it exited normally or not.
Note: when I say "Quake" in the text below, I really mean "quake,
glquake squake, qwcl, glqwcl, qwcl.x11 or quake2".
· First, you'll need the open(1) package by Jon Tombs. This is a set
of two very small programs that allow you to switch between virtual
consoles and start programs on them. Download open from
http://sunsite.unc.edu/pub/Linux/utils/console/. You shouldn't
have to do much more than make;make install to compile and install
it. Once it's installed, you need to make the open and switchto
executables setuid root. So do this:
cd /usr/local/bin
chown root open switchto
chmod 4755 open switchto
· Next, save the following code to a file called getvc.c:
___________________________________________________________________
/* getvc.c
* Prints the number of the current VC to stdout. Most of this code
* was ripped from the open program, and this code is GPL'd
*
* Joey Hess, Fri Apr 4 14:58:50 EST 1997
*/
#include <sys/vt.h>
#include <fcntl.h>
main () {
int fd = 0;
struct vt_stat vt;
if ((fd = open("/dev/console",O_WRONLY,0)) < 0) {
perror("Failed to open /dev/console\n");
return(2);
}
if (ioctl(fd, VT_GETSTATE, &vt) < 0) {
perror("can't get VTstate\n");
close(fd);
return(4);
}
printf("%d\n",vt.v_active);
}
/* End of getvc.c */
___________________________________________________________________
Compile it and install it somewhere in your $PATH:
gcc getvc.c -o getvc
strip getvc
mv getvc /usr/local/bin
· Now create a script called runvc: your $PATH:
___________________________________________________________________
#!/bin/sh
# Run something on a VC, from X, and switch back to X when done.
# GPL Joey Hess, Thu, 10 Jul 1997 23:27:08 -0400
exec open -s -- sh -c "$* ; chvt `getvc`"
___________________________________________________________________
Make it executable and put it somewhere in your $PATH:
chmod 755 runvc
mv runvc /usr/local/bin
Now you can use the runvc command to start Quake. Continue to use
whatever command line you usually use to start your game, but put
runvc at the beginning:
runvc ./quake2 +set vid_ref gl +connect quake.foo.com
You'll automatically switch to a VC, run Quake and then switch back to
X when it's done!
6.3. Keeping the mouse inside the window in X
From the Quake II readme.linux file:
By default, the mouse will not be 'tied' to the Quake2 win&SHY;
dow. To cause Quake2 to grab the mouse, select 'Windowed
Mouse' from the video menu, or type '_windowed_mouse 0' at
the console. Do the reverse to release it. You can bind
keys to grab and release the mouse in the console, like so:
bind i "_windowed_mouse 1" bind o "_windowed_mouse 0" Then
"i" will grab the mouse and "o" will release it.
6.4. 3Dfx "tweak" settings work in Linux too
You may have seen or heard mention of ways to "tweak" Quake's OpenGL
performance by setting various environment variables. These variables
are equally valid under Linux. You just set them slightly differently.
If a Windows/DOS "tweak" guide tells you to:
SET SST_GRXCLK=59
Under Linux, do it like this:
export SST_GRXCLK=59
6.5. The Poor Man's Server Browser
Joe S. (jszabo@eden.rutgers.edu) suggests:
a trick I do with qstat:
I make a file of my favorite servers, then do
qstat -f /C/quake2/file.txt | less
hit control z to suspend, then copy the ip address or hostname I want
with gpm to a command line like:
./quake2 +connect expert.eqclans.com
Then I can use fg to go back to the list later...
6.6. Using lib3dfxgl.so for Quake I**
You can use the 3Dfx mini-driver (lib3dfxgl.so) from Quakeworld or
Quake II with glquake too. Simply copy the glqwcl.3dfxgl or
quake2.3dfxgl scripts to a new file, say glquake.3dfxgl. Then edit the
glquake.3dfxgl script so it runs glquake instead of glqwcl. The same
restrictions about running as root apply here, as do the differences
between running under glibc and libc5. See the ``Quakeworld'' or
``Quake II'' sections for more information on lib3dfxgl.so.
