On a default Ubuntu (15.04) installation, We have 7 TTYs that we can switch with Ctrl+Alt+F1 (or F2 - F7), where TTY1-6 are terminals and TTY7 is the graphical X session.
I would like to have more than one TTY with graphical login, so e.g. make TTY6 an additional GUI terminal.
Is this possible and if yes, how do I set it up and are there restrictions (like don't log into the same account graphically twice)? And when I manually start an x session in a TTY, how do I quit that graphical session again afterwards and revert the TTY back to a terminal?
