OpenSuSE 11.0 KDE 3.5 Login Looping

I’m using OpenSuSE 11.0 with KDE 3.5. Everything has been working fine up til today when I tried to log in to my account. I put in the correct user name and password and KDE blanks the screen and pops me back out to the KDE login screen. I can log into root just fine and into one other account although that other account seems to be set at a very low resolution when before it would always be set at the correct screen resolution. I have to use randr to set the correct resolution.

Any ideas as to how I can fix this without having to reinstall the OS?

Did this coincide with updates?
Did you try Failsafe boot from the menu? Maybe this is graphics related?
