Title:
  Display remains fully dimmed after resume from suspend

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  After resuming from suspend the display returns fully dimmed, and
  display brightness can't be adjusted, neither using FN keys, nor using
  KDE power management control. The issue occurs regardless whether the
  suspend state was activated by low battery, by closing the display, or
  by explicitly selecting sleep mode in KDE. Killing and restarting  X
  does not solve the problem. A reboot does.
