I couldn't use the mouse to click on anything and the keyboard input didn't work also.  Even [CTRL + ALT + Delete ] didn't work.  Usually this will bring up the restart, shutdown menu.  Even this desperate action didn't work.

WS=> I think you are  mistaken about CTRl+ALT+DEL, at least in the 
version of Mint (21.1) MATE .  I tested the keystroke just now and it 
does bring up the shutdown, restart,t cancel window..

By the way, I know how it feels not to have complete control of your 
hands.  I had a stroke 20 years ago that affects my right arm.
