Can anyone lend a hand with this please? Just got hold of Doom 3, copied all the relevant files, tried to start it and - nothing. For information, hardware is an Asrock K7VT4A+ with a Sempron 2400, graphics card is an Nvidia FX5200 with 128mb, and the distro is FC3-i386, currently on kernel 2.6.10. Nvidia drivers are installed and appear to be working properly - Tuxracer works fine.

Running Doom3 from a console produces this: -

Any help will be very much appreciated.

This usually means your X display is set at 16bit color depth, it needs to be at 24

Many thanks Madluther - changing the display properties sorted it. The sound was distorted, but editing /home/username/.doom3/base/DoomConfig.cfg and changing the line seta s_driver "best" to seta s_driver "oss" resolved it.

Thanks again - it's very much appreciated.
