Title:
  Backlight control doesn't work with 3.2.0-24-generic kernel on a
  Toshiba notebook

Status in The Linux Kernel:
  Invalid
Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  When booting with 3.2.0-24-generic kernel the backlight adjustment
  stops functioning somewhere in the middle of the boot process
  (plymouth screen). When KDE is loaded, pressing the Fn-F6,F7 keys
  shows the backlight control bar, but actual brightness is not
  affected. However it works correctly when using the 3.2.0-18-generic
  kernel.

  Toshiba Satellite A200-23V.
