[Bug 137598] Re: Screen brightness resets to default (maximum) on idle with AC plugged in

 

I'm using Ubuntu 11.04 on Dell Inspiron 1464 which has onboard graphics.
I too had the same problem and I wrote a script to overcome this issue.
Thought it would good to share it with the community.

Title:
  Screen brightness resets to default (maximum) on idle with AC plugged
  in

Status in Gnome Powermanager:
  Fix Released
Status in “gnome-power-manager” package in Ubuntu:
  Fix Released
Status in “gnome-power-manager” source package in Hardy:
  Won't Fix

Bug description:
  Binary package hint: gnome-power-manager

  In Gutsy, if I adjust my screen brightness (i.e. to lower than the
  default, which is the maximum) and let the system sit idle (no
  mouse/keyboard movement) for a while, the screen brightness
  automatically adjusts to maximum on idle.  This is with the AC plugged
  in.  It seems like the brightness should NOT be changed automatically
  with the AC plugged in - and if it does, it should only be to dim it
  on idle and return to the previous level when there is system
  activity.
