There are several people who are having trouble running 3D games which use SDL (tuxracer, SOF demo, Heretic 2 demo, etc.) on Linux Mandrake 8.0 with Geforce 2 cards (see the tuxracer mailing list archives for details). Here are a few interesting details which I’ve encountered regarding this problem:
-
when I first login I am able to run ordinary GL apps (‘gears’ demo)
just fine. ‘glinfo’ reports the renderer as
GL_RENDERER: GeForce2 MX/AGP
However, when I try to run ‘tuxracer’ (or other 3D SDL apps) the screen
goes black, nothing happens for a few seconds, then the app crashes
with a segfault, and I am dropped back into my X sesssion. Afterwords,
I am unable to run any GL apps (like ‘gears’), and ‘glinfo’ now reports
the renderer as:
GL_RENDERER: GeForce 256/AGP
-
this seems to have something to do with fullscreen mode, as I can run
’tuxracer’ just fine in window mode unless I try to run it in fullscreen
mode first.
-
I downloaded the source for ‘tuxracer’ and added a few fprintfs to track
down where the problem occurs. In this case, it seemed to be during a call
to SDL_GL_SwapBuffers.
Does anyone have an idea what the problem may be? Do you have suggestions
of tests to try in order to track this down?
Thank you,

Have you contacted NVidia technical support? I haven’t seen this myself,
and I work with this combination fairly frequently. Do you have the latest
drivers? What version of the X server are you using? Did you change your
kernel recently?

I followed these instructions, and have had no problems at all. I believe
that the problem lies in the nvidia .rpm conflicting with the mandrake ones.

Strangely this only seems to happen with SDL based 3D games and programs. All of the Mesa demos run just fine (accelerated). I have the latest drivers from NVIDIA’s site, and all other software are the versions which shipped with LM8.0:
- XFree86-4.0.3-7mdk
- kernel-smp-2.4.3-20mdk
