After I press ctrl + alt + f4 the virtual terminal appears but I can't exit anymore because it is always back to "input username" and "password". Any idea how to go back to my desktop?
@Kerth G. if you press these buttons: Ctrl+Alt+(F1 to F6), you will get TTY, to exit from that you have two ways:
- Press Ctrl+Alt+F7, if you have function keys enabled press Ctrl+Alt+Fn+F7.
- Log into TTY with your user credentials, then in TTY type command:
init 5, press Enter, now you will get Graphical User Interface.
