Comment 50 for bug 32457

I just noticed today that this problem also shows up while using KVM/QEMU (current kvm package from ubuntu reps). While running a virtualized system that has control of the mouse, the screensaver doesn't notice any keypresses or mouse input as long as the mouse is grabbed by KVM's SDL window, and starts after 5 minutes. It at least detaches the mouse at the same time properly, so if you move the mouse quickly you can cancel it and click back to KVM. Pretty annoying, especially if I'm in the middle of a task in the VM.
