I have a computer that is in a public location and guest users keep hitting the shutdown option instead of the logout option as they have been instructed.
I would like to disable or remove the shutdown menu selection from the mate-menubar. I can always shutdown from the terminal.
I have tried to find it in the dconf-editor as well as mozo, but it is inaccessible from either editor.
Maybe there is a xml file that I could edit? If so, where would I find it?
I should mention I am using UBuntu 15.1 on a Raspberry Pi 2.
