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.

I'm sorry for the bad spelling and punctuation and someone in my
replies; I am struggling with a badly broken right arm, and I'm
dictating this text into my computer.

I've seen problems similar to what you describe. In fact, in recent
years I have seen them often enough that I suspect that I may be
accidentally engaging some ill considered feature to change screen
orientation or something like that, and the reason that the desktop is
no longer responding to mouse clicks or keyboard input it's because
it's waiting for me to do something else – But I don't know what.

Usually, on most Linux desktops that I have seen, the ctrl plus alt
plus del keystroke is not trapped and does not work in a graphical
desktop. I could be wrong, but what you are describing sounds more
like Windows behaviour not Linux.

The closest equivalent is Ctrl plus alt plus backspace, the intended
behaviour of which is to terminate the X11 server and immediately
return you to text mode. However because that is an extremely
destructive action, most distros disable that by default. TBH I do not
know how the Wayland display server handles Ctrl plus alt plus
backspace.

The place that Ctrl plus alt plus Del works is in text mode, in other
words, on one of the virtual consoles. So what you have to do is
switch from graphical mode to a virtual console, with ctrl plus alt
plus F1, and then you can press Ctrl plus alt plus del to repeat the
computer.
