| INSTALL for Linux Quake2 |
| ------------------------ |
| |
| 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 |
| ------------ |
| |
| Mount the Quake2 CD as one would usually mount a CDROM, this can be |
| accomplished by using the command: |
| |
| mount /dev/cdrom /mnt |
| |
| As root. Once the CD is mounted, run the setup script on the CD as root. |
| |
| $ su |
| Password: |
| # mount /dev/cdrom /mnt |
| # /bin/sh /mnt/setup |
| |
| The script will ask some questions about what options you want to install |
| and automatically install the software into /usr/local/games/quake2. |
| |
| 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). |
| |
| 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. |
