hey!

I am completely new to linux, and am having problems running games on knoppix.. I installed UT2004 and ET succesfully, but when I go to play them, either the splash screen comes up (for ut2004) then dissapears, or ET will go to a black screen like it's loading, but then go back to the desktop where my resolutions have been changed to a very low setting. To test if other games would work, I went to the standard games that come with knoppix, and NONE of them work I think there's a problem with my graphics card maybe (Geforce FX 5200 PCI), but I've been reading around and people say Knoppix should automatically detect my hardware settings. If you guys have any advice, please tell me how to fix this problem!! I am new to knoppix, so please try to keep instructions simple :-p thanks guys!
