Can't control screensaver action

This is a re-post, as I can’t see my original post and the problem is still there.

Suse 11.2 and kde, I’m trying to set up a screensaver. All the facilities seem to be there when I go System>Desktop and set the required details, but then I find the screensaver is non-operative, the screen just going blank after the preset time delay.

The set-up system does do the demo of the screensaver OK, so the software for it must be there and at least partly accessible. But it doesn’t seem to get through to the system. :’(

Check power management especially if running on battery. To be more specific, if your power management says blank screen before the time expiry you set on the screen saver, the screen will blank before the screen saver takes effect so you won’t see the screen saver at all. When you restore the blank screen, it will also recover from the screen saver. thus no screen saver.

Thanks for the tip. Sorting Power Management eventually solved the problem (the default installation had set up several power management aspects that really relate to laptops and batteries).
Happier penguin.
