Title:
  cannot adjust brightness E6530 15.04 fresh install

Status in xorg package in Ubuntu:
  Expired

Bug description:
  Press Fn + up/down arrow.

  Expected to happen: brightness goes up or down; notification in top
  right of brightness going up or down.

  Actually happened: brightness stays unaffected; notification does
  appear and respond correctly, but lies.

  Cannot adjust brightness using function key combo. Shows the
  notification as if I am adjusting it, but screen stays on max
  brightness. Brightness & Lock app doesn't adjust brightness either.

  When I switch to proprietary drivers, brightness adjustment does work.
  When I turn off the nvidia card and use the intel card, brightness
  adjustment works. But with the intel card only I don't have hdmi port
  support, so no triple monitor support. And with the proprietary
  drivers, I get horrible, horrible bugs, including one that made it
  impossible to get into my system until I modified bios settings
  related to the video card.
