You have been subscribed to a public bug by a7x (a7x):
[Impact]
* A user tries to shut down their machine. They get confused because nothing
happens
when they click shutdown.
* If someone else is logged in, they will have to ask that person to "Switch
User" to
log in and log out
* If someone else is logged in and you don't know the password of the account,
you
can't shut down
[Test Case]
* Have two login accounts
* Log both people in, via power cog->lock screen->switch user
* lock the screen on current account, via power cog->lock screen
* get back to lightdm via switch user
* log in to an already logged in account, and try to power off the machine
[Regression Potential]
* It wasn't possible to shutdown at all before
* I can't see a case for a regression, since it never worked to begin with
[Original Report]
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.s
