Hello, Mr. Watson,

I had the same problem with ATI videocard on 64-bit CentOS 5.5. It was solved after installation of last "Catalyst" driver (After disabling SELinux: http://www.crypt.gen.nz/selinux/disable_selinux.html.) - ***I am not quite sure which driver you should use with nvidia. I would also advice to check for errors your installation "log"-file (It must located in your n-vidia directory somewhere inside /usr/share/). For example, my problem was connected with GCC (I noticed errors inside log file and installed all necessary libraries).

Hope it helps. -- Best Regards, Alexander Lebedev
