  [Toshiba Satellite P850] Keyboard backlight does not work

Status in “linux” package in Ubuntu:

Bug description:
  Immediately on boot, the backlight is lit. Switching around ACPI
  settings doesn't seem to help. Booting into Windows then putting it in
  a state of hibernation, the backlights will work upon the next Ubuntu
  boot... but only that next boot.
