blank screen after 3d games exit

Hello

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.

Toshiba sattelite A100-270
Linux 2.6.34-12-default i686
System: openSUSE 11.3 (i586)
KDE: 4.4.4 (KDE 4.4.4) “release 2”

The graphics card info is:
Intel Corporation

2D driver: intel
3D driver: Unknown classic (7.8.2)
