Screen goes blank and system freezes on shutdown / logout / reboot

[Mezgrman]

From time to time (I can't find a pattern), when I shutdown, reboot or logout from the GUI, the screen turns off, but then doesn't turn on again. At this point, the system hangs and I have to do a hard powerdown. When switching to a tty, the screen goes blank as well (because it has to change the resolution) but always turns on again, so I always shutdown my system from the tty.

I'm using Ubuntu 12.04 with XFCE on a Compaq Presario CQ60 laptop.
