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.

My cideo card is: Radeon 7000/VE

any1 have any solutions?
