I agree that there isn't much point in limiting who should be able to shut down the machine when accounts are logged in, when the user has access to the power button anyway. I feel that any user should always have the opportunity to "cleanly" shut down the machine via the GUI, not allowing that is a big usability issue. Ubuntu should first warn that other users are logged in, and the offer to shut down anyway, regardless of their account status.
For a more long-term goal, it would be nice if ubuntu offered to log the accounts out for you, and in doing so saved the sessions of the logged in accounts, so no work is lost when the machine is shut down, but it would probably require a lot of work to make that a possibility. In the mean time, simply giving a clear warning that work will be lost if the machine is shut down while users are logged in, and then letting the user click shutdown is sufficient. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-session in Ubuntu. https://bugs.launchpad.net/bugs/861171 Title: Shutdown from greeter does nothing when multiple accounts open Status in The Session Menu: Triaged Status in LightDM GTK+ Greeter: Triaged Status in OEM Priority Project: In Progress Status in OEM Priority Project precise series: In Progress Status in Unity Greeter: Triaged Status in “gnome-session” package in Ubuntu: Confirmed Status in “indicator-session” package in Ubuntu: Triaged Status in “policykit” package in Ubuntu: Confirmed Status in “unity-greeter” package in Ubuntu: Triaged Bug description: Selecting shutdown from the greeter does nothing when multiple accounts are open. This is because the lightdm user (which the greeter runs as) does not have permission to shutdown while sessions are open. Inside a normal session this would just return you to the login screen. The solution is either for the indicator to say "not allowed" or to run a PolicyKit frontend in the greeter than can get the required permissions to perform the shutdown.
