Title:
  HP Pavilion g7 - brightness keys are erratic

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  The brightness keys work with stock 12.04.2, however, they are
  erratic.  For example, from full bright, I could hit the key several
  times and the screen will do nothing and then suddenly dim to almost
  the lower limit, while the indicator shows it slowly decreasing in
  brightness.

  Same for increasing brightness.  There is no set pattern, sometimes
  nothing happens at all when using one key, until I hit the other to
  reverse what I just tried to do.

  The keys DO work, they just work erratically.
