Title:
  [Lenovo Thinkpad x201] blank display on after resume from suspend

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  same hardware as bug 830355:

  this seems like a recent regression in Precise (maybe between kernel
  -16 and -18):

  after coming back from suspend, the internal laptop display is backlit
  but blank.  switching consoles, etc, doesn't help.  it does reboot on
  ctrl-alt-delay and there are blinks of wlan activity so I think it did
  wake up.
