Title:
  Screen brightness stuck at minimum

Status in “gnome-power-manager” package in Ubuntu:
  New

Bug description:
  The screen brightness was working great all day today after a fresh
  install. I used the hardware buttons and even went through the system
  testing. I just went to brightness and lock settings about an hour or
  so ago and set it to dim screen to save power, turned off the lock and
  unchecked require password. The slider was at maximum.

  I came back now and the screen is stuck in dim mode and won't come
  back to full brightness or respond to slider adjustments or hardward
  keys, even if I uncheck dim screen. I am going to restart now and
  suspect that may resolve issue but wanted to submit this info while it
  was fresh.
