desktop effects display problem

i enabled the desktop effects on suse 11, on rebooting the display goes white and stays that way. i can boot into fail-safe mode but not normal mode. is there a way to reset the desktop effects via fail-safe mode? i am using gnome. any help appreciated.

What video card are you using? What is your computer system?

What version of Compiz (compiz-fusion)?
