Blank screen doesn't recover

[Niels Roetert]

When I leave my machine for 10 minutes (default is 5) the screen blanks.
Unfortunately it doesn't come back after that, not by hitting a key or moving the mouse.
I end up stopping the machine and turning it back on again.

May be related with my Vega 64 card/drivers?
