README for Linux Quake
----------------------

This README convers all versions of Quake for Linux:
	- SVGALib Quake (squake)
	- GLQuake (glquake, glquake.glx and glquake.3dfxgl)
	- X11 Quake (quake.x11)

Requirements for SVGALib Quake:

- SVGALib 1.20 or later (/lib/libvga.so.1.2.10)
- libc 5.2.18 or later (5.0.9 will not work, /lib/libc.so.5.2.18)
  or glibc (libc6) for the glibc version
- CD-ROM for CDAudio
- Soundcard capable of mmap'd buffers.  USSLite 3.5.4 was used to build squake
  with.  Works fine on SoundBlaster 16 and Gravis Ultrasound MAX.
- SVGALib supported mouse (usually if it works with X, it'll work with
  squake).
- Kernel 2.0.24 or later
  - untested with 2.1 kernels, your mileage may vary

Requirements for GLQuake:

- 3DFX based card for the GLQuake version, VooDoo, VooDoo Rush or VooDoo2
at this writing.  In order to use 3DFX hardware, you must have 3DFX's
GLIDE drivers installed.  RPMs for these drivers are available at:
http://glide.xxedgexx.com/3DfxRPMS.html
- For the glX version, an OpenGL implementation that includes hardware
glX support.
- CD-ROM for CDAudio
- Soundcard capable of mmap'd buffers.  USSLite 3.5.4 was used to build squake
  with.  Works fine on SoundBlaster 16 and Gravis Ultrasound MAX.
- SVGALib compatible mouse for glquake or X11 for glquake.glx
- Kernel 2.0.24 or later
  - untested with 2.1 kernels, your mileage may vary

Requirements for X11 Quake:

- X11R5 later, only tested with XFree86, should work with most X Servers
- libc 5.2.18 or later (5.0.9 will not work, /lib/libc.so.5.2.18)
  or glibc (libc6) for the glibc version
- CD-ROM for CDAudio
- Soundcard capable of mmap'd buffers.  USSLite 3.5.4 was used to build squake
  with.  Works fine on SoundBlaster 16 and Gravis Ultrasound MAX.
- SVGALib supported mouse (usually if it works with X, it'll work with
  squake).
- Kernel 2.0.24 or later
  - untested with 2.1 kernels, your mileage may vary

Additional notes for SVGALib Quake
----------------------------------

SVGALib may not detect a 3-button mouse properly (it
will only use two buttons).  Check your /etc/vga/libvga.config
and set it up for your mouse type.

Additional notes for GLQuake
----------------------------

There are three different ways to execute GLQuake:

1. The binary "glquake" requires Mesa 3-D 2.5 or later installed and compiled
with 3DFX support (fxMesa..() function interface).  It also requires
svgalib 1.3.0 or later for keyboard/mouse input.  This binary is a console
application.  Mesa 3-D requires GLIDE to be installed.

2. The shell script "glquake.3dfxgl" runs the "glquake" binary after
preloading the lib3dfxgl.so library.  This is a port of 3DFX's Win32
OpenGL MCD (Mini Client Driver) to Linux.  It is faster than Mesa 3-D
since it was written specifically with supporting GLQuake in mind.
lib3dfxgl.so requires that GLIDE be installed.

3. The binary "glquake.glx" is linked against standard OpenGL libraries.
It 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.

For glquake, you must also have SVGALib or later installed (1.3.0 or later
prefered).  GLQuake uses SVGALib for mouse and keyboard handling.

If you have gpm and/or selection running, you will have to terminate them
before running GLQuake since they will not give up the mouse when GLQuake
attempts to run.  You can kill gpm by typing 'killall gpm' as root.

You must run GLQuake as root or setuid root since it needs to access things 
such as sound, keyboard, mouse and the 3DFX video.  Future versions may not 
require root permissions.

Additional notes for X11 Quake
------------------------------

This is a windowed version that is generic for X11.  It runs in a window
and can be resized.  You can specify a starting window size with:
	-width <width>
	-height <height>
	-winsize <width> <height>
Default is 320x200. It works in 16bit modes, but it's slower (twice as many
bytes to copy).

No other video modes are supported (just runs windowed).  Mouse is read, but
not "grabbed" by default.  Go to the Options menu and turn on Use Mouse to grab
the mouse and use it in the game (or type "_windowed_mouse 1" at the console).

Command Line Options for Linux Quake
------------------------------------

-mem <mb>
Specify memory in megabytes to allocate (default is 8MB, which should be fine
for most needs).

-nostdout
Don't do any output to stdout

-mdev <device> (SVGALib based versions only)
Mouse device, default is /dev/mouse

-mrate <speed> (SVGALib based versions only)
Mouse baud rate, default is 1200

-cddev <device>
CD device, default is /dev/cdrom

-mode <modenum>
Use indicated video mode

-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)

Linux Quake is *NOT* an officially supported product.  Mail about it
will be deleted.  Do not email id about this product.  If you are having
technical difficultly, you can email me, but make sure you have the correct
kernel, libc, svgalib and other software versions before you email me.
