Title:
  Backlight is off when switching to discrete AMD GPU using
  vga_switcheroo and can't be turned on

Status in “linux” package in Ubuntu:
  Invalid

Bug description:
  I have a MUXed hybrid graphics notebook with Intel Ironlake / AMD
  HD5650m GPUs and since upgrading to Ubuntu 13.04 (from 12.10) I have
  been having problems with vga_switcheroo.

  As stated in bug #1162526 I can't switch to the discrete GPU as I
  could on 12.10. Using the workaround posted by Vangel Ajanovski in
  askubuntu (http://askubuntu.com/questions/142506/hybrid-graphics-on-
  ubuntu-12-04-switching-to-discrete) I can switch to the discrete
  graphics, but when I do the laptop backlight turns off and I can't
  turn it on by any method I tried. It does work with an external HDMI
  display.
