No suspend-to-disk with kde

[Hans <hans.ullrich@loop.de>]

Hi folks, 

I am looking for a problem in KDE.

Problem: I cannot suspend to disk in KDE from the menu. The button exists, but 
has no effekt. 

Suspend-to-ram is working well in KDE.

On the other hand the commands "hibernate-disk" and "hibernate-ram" as root 
are working well. 

What command does the button in KDE call? Is this problem already known?

I am using debian/testing i386 on an EEEPC1005HGO.

If someone can also confirm this behaviour, I will be pleased to send a 
bugreport.

Best regards

Hans
