Title:
  [Dell Inspiron N5010] The System Freezes when decreasing and
  increasing screen light multiple times

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  I am using Dell inspiron n5010, I just installed Ubuntu 12.04 LTS and everything looks great, but when I tried to decrease the brightness of the screen, all of a sudden,  the system freezes, thus I restarted my laptop and I performed the same action again by decreasing the brightness and everything gone fine but when I intentionally increased the light it freezes again. Note that I uses the buttons on the keyboard to do these actions.
