Description Mike Harris 2007-04-08 20:56:32 UTC
Distribution: Fedora Core 6 Hardware Environment: MacBook Core Duo Problem Description: After resuming from a suspend-to-mem (echo "mem" > /sys/power/state), the backlight is set at maximum brightness. When pbbuttonsd is running before the suspend, the backlight control no longer works after resume. When pbbuttonsd is not running before the suspend, but started after a resume, it claims no backlight driver is available and backlight control does not work. This does not happen when pbbuttonsd is started on a "fresh" machine.

Is this already present in older kerenel like 2.6.20 or is it a regression?
Comment 4 Mike Harris 2007-04-14 04:38:09 UTC
Suspend hasn't worked correctly until 2.6.21-rc6, so it's a new bug.

What's the current status of this bug?
