Title:
  intel video suspend/resume failed, black screen with mouse cursor

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  I use suspend/resume very often, and usually after many suspend
  without reboot at the resume the screen remains black only the mouse
  cursor is visible. The mouse cursor works fine, and actually I can
  unlock the screen blind, but I don't see anything, only the mouse
  cursor. Then I switch to one of the virtual terminals (CTRL-Alt-F1)
  and back (Alt-F7) and it helps. but sometimes nothing helps, virtual
  consols work fine, but I can't reach my X anymore. Then I see in the
  syslog the follow:
