With fresh-installed 20.04 sometimes I get almost completely frozen GUI. Almost completely -- I mean I can not do Alt+F2 and r. And while the mouse pointer still moves, the system does not respond to mouse clicks or keyboard buttons.

I already have found out that in 20.04 to switch to another tty you can not use F1 or F2 in well-known Ctrl+Alt+F# combination -- only F3 and further. And to return to GUI you press Alt+F2 combination.

To summarize, I can switch to another text-mode tty, but how do I restart gnome-shell from there? I tried several commands, but neither succeeded. And the result was either error message or loosing the session and closing working programs. Of course, in the second case I have to wait for another freeze to test some another command. So the main question is:

How do I restart gnome-session from another tty in a way, similar to Alt+F2 and r specifically in 20.04 ?

UPD:

Several minutes ago I got more severe freeze. I could move the mouse pointer, but the system did not respond even to Ctrl+Alt+F# combination, and I could not switch to another tty. So the next question:

Does the ability to move the mouse pointer mean that some part of the system is still alive and I could possibly interact with it, and how do I do it if I stuck to GUI and can not switch to another tty with Ctrl+Alt+F# combination? Again specifically in 20.04

Have you tried
“RightAlt+F2 r Enter”?

Unless it was coincidence, the LEFT Alt key did nothing.

This has been frustrating me for a long time as well. LeftAlt did not do anything but RightAlt did.

Regained responsiveness and did not lose any apps, but the Desktop Environment or Gnome Menu disappeared. Have to figure out the gnome-session(?) equivalent of explorer.exe.
