I recently had a glitch (my own fault) and had to restore/rebuild. I also upgraded from SL 6.1 to 6,5. After several days struggle I can now boot  up 
and login using run level 3 but gnome does not seem to accept any keyboard 
input, either in the password dialog box if I start at run level 5 or in any window or dialog box started after a startx from the run level 3 console.
I have found reports of similar problems on the web but none of the solutions suggested (or the exact symptoms) seem to match my problem. Our system 
guru is on vacation and I have a deadline to meet so I desperately want help to get my
GUI back! My best guess is that some file leftover from the old installation is interacting badly with the new: but what? All help gratefully received!
