Title:
  Laptop screen turned off with kernel 3.8.0 in raring

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  I have a Lenovo Y580 Ideapad. When booting with the 3.8.0 kernel, the screen turns off when the ubuntu logo and progress bar should display. Xorg starts, I can hear the startup sound, but the screen is turned off. Booting on the 3.5.0 kernel works fine.
