Title:
  [Samsung NP535U3X-A01BD ] Display remains off after resume from
  suspend

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  After I resume from a suspend, the display does not turn back on.
  However, I hear sounds as if just booted on to the login screen. But
  with all combinations of Keys, Ctrl-Alt-Delete, Space, lid-turn-
  on/off, backspace, brightness increase/decrease nothing helps to turn
  the display back on. The issue had been same with Lubuntu 13.04 and
  13.10 as well.

  WORKAROUND: Hibernate via:
  echo disk > /sys/power/state
