Contrary to my comments to bug 485475, i also happens without kvm or
virt-manager running.
It also happens with only one screen (the laptop's builtin) attached.
More details on my setup, perhaps we've got something im common
Screensaver: Blank Screen
Graphics driver: Nvidia propietary installed
Have you tried the workaround mentioned in comment #2 of bug 485475?
