Title:
Sometimes can't adjust screen brightness
Status in “linux” package in Ubuntu:
Expired
Bug description:
Sometimes, the screen brightness controls work on my laptop, and
sometimes they don't. I haven't noticed any pattern as to when it
works or doesn't.
When it doesn't work, I press Fn+F6/F7 to adjust the screen
brightness. The notification pop-up appears, showing the new
brightness setting -- but the brightness doesn't actually change.
Rebooting fixes the issue. There is nothing in syslog or dmesg.
