Multiple logons problems

[Volkan Gezer]

I login for a user (this is ctrl+alt+f7) and create another session for another user (ctrl+alt+f8).

I switch to the second user, do some operations and log off. It goes back to login screen (LightDM) in ctrl+alt+f8, not in tty mode back.

Then I switch to the first user and shutdown computer from here. It logs off then goes into boot mode but does nothing else (only writes Enabling Laptop Mode). The only way to continue shutdown operation is going to Lightdm screen of second user and clicking to Shutdown from there, too.

In conclusion, I always need to click Shutdown for every user.
