Bug Description
Since the upgrade from intrepid to lucid, the energyprofiles in KDE dont work properly on my lenovo T60.
Whenever a new profile is activated, display goes to lowest brightness. When I use the function keys I can dim brighter, but the onscreen display does not show the brightness.
Every event that occurs in the profile will dim the display to low brightness again.
