Comment 13 for bug 889278

I tried 5 and 5 minutes, no dice. Perhaps it kicks in when lock screen is _longer_ than the suspend setting. Iirc this kind of used to be the case back in the day with xscreensaver, acpid would suspend your laptop and then when you opened it up again you would see a screen, then when xscreensaver got a timeslice it would lock your screen so you would have to log in.
