There should be no requirement to log-in in order to shut the machine down if you have physical access, the power button should initiate this in an orderly manner (warning/prompting as required).
Basically, if the person at the power button wants to, they can hold the button in for 5 sec and power off brutally, or pull the AC supply! Hence the system should be designed with this in mind and offer them the option, without super-user rights being needed, to shut down in as orderly a manner as possible even if others were logged in. Having been warned of that just in case. Remember, they are physically at the machine's power supply control and can/will use that if it won't respond! -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to lightdm in Ubuntu. https://bugs.launchpad.net/bugs/915382 Title: ACPI events to shutdown/reboot don't generate a popup like after logging in Status in “lightdm” package in Ubuntu: Triaged Bug description: There was a bug against virt-manager* where sending a "reboot" or "shutdown" event to a client seemingly doesn't do anything. Turns out that this only happens on the login screen, inside a session you get a popup asking what to do after the power button has been pushed. So something is wrong on the lightdm session, that prevents the popup from happening. This happens on real hw as well; if you hit the power button while looking at the login screen, nothing happens. * bug 228690 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lightdm/+bug/915382/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
