monitor power saving

[Christian Fröbel]

Hi there,

on my dapper with KDE 3.5.3 monitor power saving does not work. When I go to 
System Settings->Hardware->Display->Power Saving, it's always disabled. Okay 
I enable it and set the timeout to 5 min. But the system doesn't care. I do a 
reboot and go to the settings tab again. And it's magically disabled again. 
Strange.

What's confusing me even more is, that I can change those settings both in 
user- and admin-mode. Strange, too.

Any ideas?

thanks,
  Christian
