Quake2 3.20 For Linux --------------------- Please see the readme.txt file included for general information about the game. This file contains Linux specific information. Please see the file 3.20_Changes.txt for changes from previous versions. Requirements ------------ Quake2 for Linux supports the following video subsystems: - SVGALib Console Graphics (ref_soft.so) - Requires SVGALib 1.2.0 or later - X11 Window Graphics (ref_softx.so) - X11R5 or later, XShm shared memory extension supported - 3DFX fxMesa with Mesa 3-D or 3DFX Miniport (ref_gl.so) - Mesa 3-D 2.6 or later, specifically compiled for 3DFX support Mesa 3-D 2.6 compiled with 3DFX support is provided with this archive. - Generic glX (X11) based OpenGL (ref_glx.so) - Requires a glX based hardware accelerated OpenGL implementation. Mesa 3-D 2.6 supports this on 3DFX hardware. Also included is a specific 3DFX mini-OpenGL implementation for running Quake2 on 3DFX hardware. Installation ------------ Make sure you have the appropirate hardware, drivers and libraries installed for the renderer you are going to play on. Quake2 for Linux supports the following renderers: - ref_soft Software rendering under SVGALib (console only). SVGALib 1.2.10 or later is required. Note that SVGALib 1.2.11 supports the ability to run a SVGALib application under X11 as it will automatically allocate a new console. The default mode is 320x240 (ModeX) since that is the lowest resolution supported by Quake2. If SVGALib supports your video card, higher resolution modes such as 640x480 and 800x600 are also supported. Please note that you may need to configure your mouse for SVGALib in /etc/vga/libvga.config (or /etc/libvga.config). - ref_softx Software rendering under X11. This uses the MITSHM Extension and should work will virtually all Linux X Servers. **NOTE: Do not resize the window under X11. You must use the Video menu to change resolution/window size. By default, the mouse will not be 'tied' to the Quake2 window. 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. - ref_gl This render can be run with two different OpenGL drivers: Mesa 3-D ontop of Linux GLIDE, or 3DFX's mini-OpenGL Quake driver. For Mesa 3-D, the necessary libMesaGL.so.2.6 is included with this archive. You must copy it to /usr/lib or /usr/local/lib and run ldconfig (as root) in order to use it. You can do this as follows: tar cf - lib*GL* | (cd /usr/lib; tar xf -) You should use tar to keep the symlinks intact. Once you copy them over run ldconfig. You must also download and install the Linux GLIDE drivers at http://www.3dfx.com/software/download_glidel.html And install them as instructed. RPMs for GLIDE are available at : http://glide.xxedgexx.com/3DfxRPMS.html With version 3.20, the GL library is entirely runtime loaded. This means you can specify what shared object to load for GL display. To use Mesa 3-D GL (console), run quake with: ./quake2 +set vid_ref gl +set gl_driver libMesaGL.so.2 To use the 3DFX OpenGL Miniport, run the included quake2.3dfxgl: ./quake2 +set vid_ref gl +set gl_driver lib3dfxgl.so The gl_driver cvar indicates the name of the library to load for GL functions. It can be in any directory listed in /etc/ld.so.conf or in /etc/quake2.conf **NOTE: There is a problem on libc5 systems where a vid_restart (causing a reload of the video system) will crash. There doesn't seem to be a solution to this yet. It looks to be some sort of ld.so dynamic loading interaction with SVGALib and ref_gl.so. A work around is to start in software mode (./quake2 +set vid_ref soft), then use the menu to set your mode and a vid_restart will work when going from software to GL. Exit out then and save your video mode settings. This problem does not occur on libc6 (glibc) based systems; vid_restart works fine on there. - ref_glx ref_glx should run on many different hardward OpenGL implementations under Linux and X11. This binary is an X11 application and must be run under X11. It will work with Mesa 3-D as a standard glX based OpenGL applications. If the Mesa 3-D library is compiled with 3DFX support, you can have Mesa 3-D support 3DFX hardware under X11 by setting the enviroment variable "MESA_GLX_FX" to "fullscreen" for fullscreen mode and "window" for windowed mode, eg. "export MESA_GLX_FX=fullscreen" for sh or "setenv MESA_GLX_FX fullscreen" for csh. As with ref_gl, the "gl_driver" cvar indicates the shared library to load for OpenGL functions (the glX functions must provided in that library as well). To install the Quake2 data files, mount your Quake2 CD and copy the directory install/data to the location where you want Quake2. You can also symlink it, but I don't recommend that. Around 200MB of disk space is required for a full installation. For example: cp -r /mnt/cdrom/install/data/* /usr/games/quake2 Permissions ----------- Quake2 requires root permissions to use the software (SVGALib) and GL (MesaGL w/3dfx) renders. In order to make this secure, some special considerations must be made. Quake2 should get setuid root: chown root quake2 chmod 4711 quake2 And the ref_soft.so and ref_gl.so files must owned by root. The file /etc/quake2.conf must be installed. This file contains a single line with the path of where the ref shared libraries can be found. A sample one is included that lists /usr/games/quake2 as the default path. The libraries are only loaded out of the directory listed in /etc/quake2.conf for security considerations. Special permissions are not required for the softx renderer, but quake2 may still need to be setuid root to open the sound device (quake2 will give up setuid root permissions before loading softx). NOTE: If you use a setuid quake2 binary and run it as a normal user, it will NOT be able to switch renderers on the fly because root permissions are given up after the renderer is loaded. You can switch renderers on the fly if you run quake2 as root (su or log in as root). NOTE: When the quake2 binary is run in dedicated server mode (+set dedicated 1), no special permissions are required and /etc/quake2.conf is not read since no renderer is loaded. ---- The first time you run Quake2, it will use ref_soft or ref_softx based on whether a DISPLAY environment variable exists. To force the loading of a specific renderer at load time, use the following command lines: ./quake2 +set vid_ref soft ./quake2 +set vid_ref softx ./quake2 +set vid_ref gl ./quake2 +set vid_ref glx Linux Specific Cvars -------------------- To set this, use +set on the command line, i.e.: ./quake2 +set cd_dev /dev/hdc +set sndmono 1 nocdaudio (defaults to 0) Do not enable cd audio if not zero sndbits (defaults to 16) Set sound bit sample size. sndspeed (defaults to 0) Set sound 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 (defaults to 2) Indicates stereo or mono sound. Defaults to 2 (stereo). Use 1 for mono. nostdout (defaults to 0) Whether to output console msgs to standard out. Non-zero is cease output. Dedicated server ---------------- To run Linux Quake2 as a dedicated server, just run it as follows: ./quake2 +set dedicated 1 You can also set dmflags, timelimit, etc. in a config file, like so: set timelimit 20 set fraglimit 25 set dmflags 532 map fact3 Then exec that config file on load, like so: ./quake2 +set dedicated 1 +exec server.cfg If you use a config file, you must put a 'map' command in it or the server won't load a map. To run a dedicated server in the background, use this; nohup ./quake2 +set dedicated 1 +exec server.cfg & A better way is to run Quake2 on a tty via screen. screen can be found at ftp://prep.ai.mit.edu/pub/gnu/screen-3.7.4.tar.gz, but it comes with most modern Linux installations now. ----------------------------------------------------------------------------- Linux Quake2 is an unsupported product.
