[Alexandros Michalopoulos]

Sometimes when I do a reboot, especially after an update that prompts me to do so, Ubuntu won't load the Desktop. The Ubuntu login sound theme plays normally, the mouse cursor shows for ~5 seconds (overlaid on the plymouth logo), then the monitor enters sleep mode. A restart always fixes things.
