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.
