Public bug reported:
The brightness keys (aka F1/F2) on my MacBook Pro 9,2 have been working with
12.04 and 12.10.
Now after the upgrade to 13.04, when I press them I see the brightness
notification, but the actual brightness of the screen doesn't change. It is
set to the max level when booting and stays at this level.
Thanks for your help!
