Scott Severance, this bug was reported a while ago and there hasn't been
any activity in it recently. We were wondering if this is still an
issue? If so, could you please test for this with the latest development
release of Ubuntu? ISO images are available from
http://cdimage.ubuntu.com/daily-live/current/ .
If it remains an issue, could you please run the following command in
the development release from a Terminal
(Applications->Accessories->Terminal), as it will automatically gather
and attach updated debug information to this report:
apport-collect -p linux <replace-with-bug-number>
** Tags added: bios-outdated-f.19 needs-upstream-testing regression-
release
** Changed in: linux (Ubuntu)
Status: Confirmed => Incomplete

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.
