Title:
  Changes to screen brightness delayed

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  This has changed (during a recent update?) but under 14.04 my hotkeys
  for changing the screen brightness no longer work immeidately. Their
  effect is now delayed by about 10 seconds.   there is no hangup to the
  user interface during that time.
