X11 login screen receives no input from mouse or keyboard

[Alex Janssen]

I recently upgraded from 6.0.6 LTS to 8.0.4 LTS via the alternate 
install CD.

After the upgrade was finished the X login screen receives no input from 
the mouse or keyboard, although I can switch to a console screen via 
ctrl-alt-F1.

I tested /dev/input/mice via "sudo hd /dev/input/mice".  I get input 
from the mouse and obviously the keyboard works.

I ran dpkg-reconfigure xserver-xorg and it still does the same thing.

Any ideas?

Thanks for your help,
Alex
