Title:
  Screen brightness set to minimum

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  I wanted to try Natty from an USB stick. The purple screen at the
  beginning displayed correctly, then the laptop screen went blank. Some
  seconds later I heard the startup sound, but the screen was still
  black. Holding the laptop in an angle, I can notice there is something
  being displayed on the screen, such as the panel, and I can even open
  dialog boxes by clicking at random, but they look only as faint darker
  spots on the screen. It seems to me that the screen brightness is set
  to minimum, but the brightness controls won't work. The problem
  persists in Oneiric Beta 2.

  No display problems with Maverick.

  I have a PackardBell Butterfly XS

  I made lspci | grep VGA in the terminal and got this:
  00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07)
