Title:
  [HP Pavillion dm3-1109TU] Brightness setting not remembered after
  reboot

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  With Ubuntu 14.04.1 with system updated today, I found that screen
  brightness not remembered after reboot. Always back to 100% in every
  system startup.

  This is a regression since it's not happen in Ubuntu 12.04 (kernel
  3.2).

  I can't do testing with kernel 3.16 rc7 because of the problem I told in Bug #1349080 :
