Title:
  screen brightness adjustment misses levels

Status in “gnome-power-manager” package in Ubuntu:
  Expired

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

  Maverick only supplies 4 brightness increments on my PC, although I
  have 8 possible increments - my LCD supports the following levels:

  $ cat /proc/acpi/video/VID/LCD/brightness 
  levels:  12 24 36 48 60 72 84 100
  current: 72

  For instance, when the screen is set to maximum (100), pressing the
  brightness down keys (FN-down arrow) makes the brightness go to 72,
  then 48, then 24, then 12. Pressing up from here makes the brightness
  go to 36, then 60, then 84, then 100.

  I'm currently running a 2.6.36-rc3 kernel, but the problem also exists
  in the stock Maverick 2.6.35 kernel.
