Linux Mint won't shutdown [closed]

edit

This is an FYI mostly. On Linux Mint I cannot get the gnome session to quit when the Quickstart is enabled. I have this behaviour on three difference Linux Mint (and one PinGuyOS, a Linux Mint flavor) installs on three different computers. I select "shutdown" or "reboot" or "log out" and nothing. When the Quickstart is disabled, these functions work correctly. Not a huge deal, but that's how I worked around the problem. Is there any news regarding this?
