Comment 8 for bug 993440

I see now that it fails to suspend after all. The patch i've committed does add the option to suspend, and gnome-control-center correctly updates the setting in dconf. The critical power level notification also tells that the machine is going to "suspend very soon". But the machine shuts down instead of suspending. It seems this is related to bug #160200, and the underlaying issue is probably in acpi.

As for now, all other options than "shut down" seems useless.
