Problem with Display "Special Effects"

I am using openSUSE 11.0

I tried setting Display Special Effects. All I got was a white screen with a black box in the middle. Pressing various keys gives me a white screen, black screen and the black box on a white screen. I have tried rebooting and still get the same result. So I have now lost access to my whole setup.

How can I get back to the point before I started fiddling with Special Effects?



This may help…?
Desktop Effects crashed KDE 4

If your still having issues, what video driver where you using, nvidia,
ati, intel?
