Google Earth log off the system

I, i installed opensuse 11 and i tried to install google earth 4.2, at the first installation it worked well but it told me to renew the display driver because it was working in gpl software. I changed the resolution of the screen from 1280x1024 sxga to 1024x780 xga and back again, in ati mobility radeon x600 se, and after that when i tryed do launch it again the system logs off and return to the log in screen.
Any tips?
