Known Linux Quake problems?
Here is an excerpt, as of January 7th, 1998. I omitted most stuff not specific to &3Dfx; hardware. • You really should run Quake2 as root when using the SVGALib and/or GL renders. You don’t have to run as root for the X11 refresh, but the modes on the mouse and sound devices must be read/writable by whatever user you run it as. Dedicated server requires no special permissions. • X11 has some garbage on the screen when ‘loading’. This is normal in 16bit color mode. X11 doesn’t work in 24bit (TrueColor). It would be very slow in any case. • Some people are experiencing crashes with the GL renderer. Make sure you install the libMesa that comes with Quake2! Older versions of libMesa don’t work properly. • If you are experience video ‘lag’ in the GL renderer (the frame rate feels like it’s lagging behind your mouse movement) type “gl_finish 1” in the console. This forces update on a per frame basis.
