Title:
  screen brightens when idle, rather than dimming

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

Bug description:
  This may be related to the bug #498974
  (https://bugs.launchpad.net/ubuntu/+source/gnome-power-
  manager/+bug/498974)

  When the screen is turned to a high brightness, if I haven't touched
  the keyboard or mouse for a while the display will dim a bit. This is
  normal.

  However, when the screen is at a low brightness, at idle the screen
  will actually brighten instead of dim!

  It seems like the "brightness to dim to" is a hardcoded value, rather
  than relative to the current brightness. Hence, the hardcoded
  "brightness to dim to" is actually brighter than what I have my screen
  set to.

  It seems related to that other bug, but the symptoms they report are a
  little different. Mine just gets a bit brighter. The other bug report
  describes the screen getting to full brightness before dimming
  somewhat again, ending off with a higher brightness than when the
  keyboard and mouse are not idle.
