Thanks everyone for your helpful advice. It seems that running the following command, sudo dpkg-reconfigure xserver-xorg, helped to fix the issue with the resolution.

I've had to work around this problem by opening the system settings once I login to KDE and clicking on the screen resolution settings option. If I'm lucky, this will resize the screen to the size I want (1280 X 1024). Sometimes, however, this results in a crash of KWIN or some other display-related application. Also, when I attempt to switch sessions, I run a greater risk of crashing KWIN. And when I do have multiple sessions running, I don't see the login screen when attempting to switch between the sessions. I happen to know that one should be there and so I end up blindly typing my password and the switch tends to execute successfully. I'd appreciate any help in resolving this. thanks, Ifeanyi </blockquote></div></div> You can resetup the xorg.conf file by running: sudo dpkg-reconfigure xserver-xorg Also sometimes a line in the xorg.conf file "Virtual 1024x768" or similar causes some screens to 'scroll' or not look proper, usually with the logon or kdm screens... Usually removing this line from the conf file fixes this. It seems that hardy really removes alot of sections from the conf file (uses defaults) so there's no template to go by... You can look though mine if it helps. Don't copy it as the bus id of the card and many other things are not right, but it gives a good template to go by.
