Christopher, why did your scripts inspect this bug? It was marked as a
duplicate of another bug and I cannot see any good reason for removing
the duplicate status. I am putting the duplicate back, so that this bug
falls off the visibility again, and the stronger bug wins.
Please inspect your scripts, I believe they are incorrect.

laptop brightness keys regression
Status in “linux” package in Ubuntu:
In 12.04 LTS and 12.10, the fn+f8 and fn+f9 keys properly adjusted my
Thinkpad T530's display brightness perfectly.
I upgraded to Raring on Mar 17, and the brightness keys no longer
work. The indicator appears but the slider does not slide and the
screen brightness does not change.
The brightness slider on the brightness and lock control panel feels
like it has lost granularity -- but I cannot recall the exact behavior
of the older slider.
