Screen switch to Powersave while running Games

Hi everyone,

hopefully someone could point me to the solution to the following problem:

When playing Games such as Vamos, Vdrift or Torcs, my Screen is switching to Powersave Mode and getting black.

Moving the Mouse and the Screen is active again. But the Keyboard is active all the time! This is annoying.

Is there a setting I must change?
My System: Suse 11.2 KDE 4.3.5

I have never had this kind of Problem in Suse 10.3.

Thanks in advance.

Make sure this is off

switch off powersave everywhere!

THX, that seems to work.
