Title:
  brightness adjust 3 steps from hard (Fn) keys

Status in Gnome Powermanager:
  New
Status in “gnome-power-manager” package in Ubuntu:
  Confirmed

Bug description:
  the brightness adjusts in 3 steps, i thought it was annoying but
  adjustable in gconf; finally investigated and saw it wasn't :]

  if i echo 0 > /sys/module/video/parameters/brightness_switch_enabled
  it reduces one of the extra steps

  if i killall gnome-power-manager i get no backlight adjustment, from
  my understanding its solely responsible, but i can't find the extra
  brightness event input, acpi_listen shows the video adjustment, as
  does input-events 4 (the video device)

  X opens the video event device as an input but i don't know if that
  means g-p-m will see it as another event

  hoping someone can tell me more about g-p-m and where it gathers
  events so i can finish investigating, or solve the bug outright :]
