Safest way to shut down upon a freeze

Question

What is the safest way to shut down when the system gets completely frozen? Is there anything we can do outside of pulling the cable?

Does this answer your question? What is the equivalent of 'Control-Alt-Delete'? — user68186, Apr 05 '20 at 12:54

Simply open a new tty using Ctrl + Alt + F3, login using your username (name of the home directory) and use shutdown now . This should work

Depends on what you mean "completely frozen". Perhaps only the GUI is frozen while the system is still alive? In this case you could launch a tty, by Ctrl + Alt + F2/3/4/5..

When you've logged in into the tty, run htop and kill the processes that seem to be troublesome.

I don't know what it can exactly mean either. Frozen, that is, all audio stops, you cannot move your mouse, et cetera. Ctrl-alt+F I did not try yet. – John Smith Apr 05 '20 at 13:24
