Hi First off Centos is Great!! I have thin clients running under Centos with no problems at all ! My question is not a major problem - in my spare time I play a 3D demo Unreal Tournment 2003 , just wondering if anyojne knew why my 3D screensavers would have suddenly not work? My video card is Nvidia mX 4000 , no problem running the UT2003 Demo I have on it , but for some reason all I get is a black screen where my screensavers should be? cheers Mike
