[Bug 1156477] Re: laptop brightness keys regression


*** This bug is a duplicate of bug 1098216 ***

It's not a script? How did you even find this bug? :)

The raring SRU completed successfully, and saucy (which I'm running now)
didn't exhibit this problem thanks to the bughunting done before the
raring SRU. As far as I'm concerned this is handled...

  laptop brightness keys regression

Status in “linux” package in Ubuntu:

Bug description:
  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.
