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 reliable xscreensaver.

$ sudo apt remove xfce4-screensaver
$ sudo apt install xscreensaver

I would suggest replacing your current screensaver with xscreensaver.

Remove the screensaver

In addition, the Xubuntu mailinglist offered an alternative, i.e. not using a screensaver at all. The steps are:

sudo apt remove xfce4-screensaver

Next, disable start on login of xfce4-screensaver: In Xubuntu it is Whisker > Settings > Session and Startup > [] Screensaver (launch screensaver and locker program)

Finally:

xfce4-screensaver-command --exit

It also should be noted that turning off a screensaver involves setting power manager, turning display power management on (yes, not off) and move the sliders to never blank.
