Summary: Suspend-to-mem on MacBook destroys backlight control
Kernel Version: 2.6.21-rc6
Status: NEW
Severity: normal
Owner: [EMAIL PROTECTED]
Submitter: [EMAIL PROTECTED]
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.
