Oh, and as far as permissions go, the only ones I change are those to the user directories in /home. These default to 755 but I chmod them to 700 so that a user can access his/her own files, but cannot see other users' files....

Like I said, I always do this and have had no problems, but I just thought I should mention it.

Maybe I could create an .Xauthority file for each user myself?

Would a lspci -v dump help you help me?

TIA,
