Title:
  Screen Brightness problem

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  well..when I first installed my Ubuntu 14.04, my brightness button was
  working just fine, but now, when I try to do it, it gets kind of laggy
  and doesn't adjust the screen, only the brightness of the own bar
  changes a little.
