** Description changed:

  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.
