Sorry, played all my cards trying to initialize your video system.
Armagetron won't run on your computer. Reason:

Couldn't set video mode: Couldn't find matching GLX visual

I'll try again from the beginning, but the chances of success are minimal.

Fatal signal: Segmentation Fault (SDL Parachute Deployed)

i've installed the nvidia-glx and glx-dev packages through synaptic
i dont, however, see an nVidia logo when i startup, and i dont think i've removed it by editing that whats-it file

i get a similar error when i try to run warsow

help please?

Seems that you forgot to enable (not the same as install) 3D acc.

write:
sudo nvidia-glx-config enable
in the terminal and reboot.

If it doesn't help. Then:

sudo gedit /etc/X11/xorg.conf

Find Section Device, under it change Driver "nv" to Driver "nvidia"

Also check the Section Module if you have the line that says: Load "glx"


reboot.
