  Brightness keys not working Lenovo E430.

Status in “linux” package in Ubuntu:

Bug description:
  Ubuntu 13.04, Lenovo E430.

  The brightness keys on this laptop act a little strange. If I hit the
  brightness down key, it will drop the brightness to about 1%. If I
  press brightness up, it does nothing at all. I see the pop ups come up
  as if it's trying, but it never actually changes the brightness at

  If I go into the brightness and lock menu from system settings and
  adjust the brightness via the slider it works absolutely fine. This
  makes me wonder a few things. What is the difference between the
  function keys and the slider in system settings? How is it one works
  and the other doesn't? Is there a way to re-map the function keys to
  adjust the brightness slider?

  Also - I tried the mainline 3.9 kernel and it acted 100% identical to
  the Ubuntu 3.8 kernel.
