Title:
  [Dell Studio XPS 1340] Screen backlight doesn't turn on after suspend
  when using proprietary NVidia drivers

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  By default this system uses the Nouveau drivers, with which Unity and
  the desktop work correctly, but the system becomes unresponsive when
  trying to resume from suspend
  (https://bugs.launchpad.net/ubuntu/+source/linux/+bug/754711). The
  usual workaround is to use the proprietary drivers.

  I installed the proprietary drivers, ran into  bug1069888, and then
  tried to establish suspend/resume behavior.

  System enters suspend correctly, then resumes but then the screen is
  unusable (all black) and the backlight is turned off. I was able to
  SSH into the system so it seems to be active, but is useless because
  of the screen condition.

  I tried "blind typing" to see if only the screen has this problem or
  the keyboard is also unresponsive. It turns out, it is, nothing I type
  gets registered by the system.
