How to exit the virtual terminal?

@Kerth G. if you press these buttons: Ctrl+Alt+(F1 to F6), you will get TTY, to exit from that you have two ways:

1. Press Ctrl+Alt+F7, if you have function keys enabled press Ctrl+Alt+Fn+F7.
2. Log into TTY with your user credentials, then in TTY type command: init 5, press Enter, now you will get Graphical User Interface.

To log out of a virtual console, you need to type exit.

Your Desktop Environment will be started in one of the virtual terminals. On Ubuntu, it is on tty7. So to get to it, press Ctrl + Alt + F7.

Usually one virtual terminal (1 or 7) is reserved for the graphical environment, so to come out of a virtual terminal either try CTRL + ALT + F1 or CTRL + ALT + F7.
