--- Comment #13 from David Gibson dgibson@redhat.com --- I just got a chance to try, and no it doesn't help. I'm actually pretty sure I've hit this problem without virt-manager running anyway, so I no longer think that's a good theory. However I think it may have something to do with workrave. I'll try killing that instead of the screensaver when it next happens.
I haven't been able to reproduce by manually locking the screen.
