Public bug reported:
Brightness control using Fn + F8/F9 has regressed from the 3.8 kernel
used in 13.04.
Expected:
9 levels of brightness adjustment using Function Keys
Experienced:
5 levels of brightness adjustment with blank levels with "blank" levels
where a key press results in no brightness change even though indicator
showed change.
Regression proved by reverting to 3.8 kernel resulting in expected
behaviour.
