Blankscreen after Close lid

Hello everybody, i have problems on Lid Closing.

Im using OpenSuse 11.3 (updated). i use KDE 4.

Everytime i close the laptop lid, the screen always blank.

i tried to modify the profile on profile management, i change the close lid section with Lock screen, suspend and even do nothing. but still blank screen.

any ideas how to solve this? thanks

Take a look at power management operations for powered vs battery actions. Profile and power have similar settings but power will take precedence
