Title:
  gnome-power-manager brightness levels are not right

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

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

  Hello, Ubuntu geeks.
  I have a kinda old laptop. Just installed Ubuntu 10.10 Mavericks but I come across some problems. Most inportantly is the brightness control problem. My laptop has 8 levels adjustment settings. But only 4 levels can be adjust when I press Fn+F7 and FN+F8 to change to the maximum  or minimum. I think this is a bug and wanna solve it, so I reported here. I used this command below to check the brightness levels info in the /proc/acpi/video/GFX0/DD03/brightness.
  cat '/proc/acpi/video/GFX0/DD03/brightness
  It returns these values below.
  levels: 13 25 38 50 63 75 88 100
  current: 63
  And I checked the /proc/acpi/video/GFX0/DD03/EDID, it's empty. Is this normal or Ubuntu hasn't recognized my laptop LCD correctly? 

  I did dmesg|tail -5 command and it returns this below.

  Ismod attached.
  Please help me make this amazing OS run flawlessly on my laptop. Thanks in advance.
