[Bug 579254] [NEW] Low brightness (dimmed) on resume

[Launchpad Bug Tracker]

You have been subscribed to a public bug:

Hello.

Sometimes my laptop display is unable to set a reasonable brightness.
It's completely dimmed and changing brightness doesn't make any
difference. It's somewhat according to the description of bug #451282
(https://bugs.launchpad.net/ubuntu/+source/linux/+bug/451282) but it
isn't as common as their bug seem to be. It was 8 days between this and
the last time it occurred and there was multiple suspends/resumes during
this time, both with AC and on battery. Using an external display works
successfully (correct brightness) and rebooting the system successfully
restores the system.

It first occurred sometime between the last beta and final release of
Ubuntu 10.04.

Description:	Ubuntu 10.04 LTS
Release:	10.04

Steps to reproduce:
1. Suspend
2. Resume
