Before logging in, I can move the mouse to top right and select power off or reboot. But after logging in, no click, either right or left, is effective.
The keyboard does not accept input after logging in, except for Ctrl+Alt+F3.
I can get to a terminal via Ctrl+Alt+F3 to issue commands.
Any suggestions on what I might try to fix this issue? I am lost.

Replace the screen saver
I experienced something similar on Xubuntu LTS 20.04 with the keys of my Logitech K400 Plus wireless touch keyboard becoming unresponsive after a while except for console switching with Ctrl+Alt+F1..F6.
As it turned out, the buggy
xfce4-screensaver
was kicking in. I replaced it with the more reliablexscreensaver
.I would suggest replacing your current screensaver with
xscreensaver
.
