I want to add a bit here to raise awareness of the fact that the issue goes beyond the scenario in the description. My computer is on uninterrupted power supply (UPS), which gives me 10-20 minutes to shut it down if power goes out. My monitor draws to much to be supported by the UPS, so it goes out with the power. The standard and working solution in every other distro and Windows and MacOS is to press power switch button, which pops a timed dialog and, if no action is made, shuts down. The current Unity dialog has not keyboard shortcuts, only mouse buttons. It is impossible to make a mouse selection without having a monitor on. This is a serious flaw!
