Public bug reported:

After upgrading from 14.04 to 14.10 my screen goes black at random times.
The sound keeps playing so I know it's still running.
The only way I can get the screen back is by pressing the power button, which will show the shutdown selection window and unblackens the screen.
My laptop is a Lenovo ideapad z580
Intel Core i7-3520M
integrated graphics
6 gb ram
Ubuntu 14.10 64-bit
