Title:
  Screen brightness inverted when idle

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  When I'm running on battery, the following happens after about 20
  seconds or so of no user activity:

  - First, the screen gets *brighter*--nearly 100% brightness.

  - Second, the keyboard brightness keys are inverted: the brightness up
  key decreases brightness and vice versa. However, brightness only
  varies over a narrow range which is entirely brighter than the normal
  brightness for running on battery.

  - Moving the mouse or hitting a "normal" key restores brightness to
  the expected levels for battery mode and restores the brightness keys
  to normal operation. After about 20 seconds of no user input, the bug
  pops up again.

  - When I'm running on AC power, there's no change in screen brightness
  on inactivity. However, after inactivity, the brightness keys are
  still inverted. This mode is so subtle that for a long time I never
  noticed it and thought that this bug only occurred on battery.

  I'm running Oneiric with kernel 3.0.0-15-generic. I first noticed this
  bug upon upgrading to Oneiric, but another bug kept me running a Natty
  kernel (2.6.38-10) until recently. Natty kernels didn't exhibit this
  bug, so it's a regression. Unfortunately, I'm not running Precise, so
  I can't test it.
