Here's another scenario: A laptop is shared by multiple members of a household. User A is the admin, User B is not.
User B steps up to laptop with the intention of shutting it down to leave with it. User A is currently logged in. We have two choices here: 1- Present a warning dialog to User B saying that shutting down the laptop may cause User A to lose unsaved data in open applications, but allow him to shut the laptop down anyway. 2- Present an error message saying an admin is required to shut the machine down, at which point User B simply turns the machine off with the power button, and causes disk corruption. -- 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.
