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 Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/915382 Title: ACPI events to shutdown/reboot don't generate a popup like after logging in To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lightdm/+bug/915382/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
