Occasionally I need to drop into the text console (via ctrl+alt+f1), usually to kill something. When I try to return to the graphical console (via ctrl+alt+f7), I've been logged out of my GUI session and have to log in again and reopen all of my applications. Is there a way to keep the GUI session from closing when I jump to the text console? Previous versions of Ubuntu never logged me out like this when using the text console.
I'm running Ubuntu 18.10 with GNOME classic desktop.
