blank screen after 3d games exit


I’ve just installed/updated to opensuse 11.3, I’'m not able to install and run 3d games like smokin guns and saurbratten, which were previously installed and running.

I don’t know if this is linked to the other problem, when I run 3d games then quit, X is killed completely and the only option is to press the power switch.

This is what I’m running.
