So, you can move the mouse?

And where are you typing these commands? Doing a Crtl-Alt-F2?
I sued Shift-Tab to get to an open Konsole. Note that everything except
Plasma still works, my other windows are running etc. I even sent that
report from Evolution before logging out.

Back in the F26 or F27 days I was having some issues. Forgot the circumstances but back
then I was
advised that doing
kquitapp plasmashell
plasmashell &
Yes, I remembered too late that I even have a script for that (BTW it's
now kquitapp5). However:
It just happened again, this time when I came back from my lunch break.
At least that eliminates by backup system from suspicion.
This time I just logged out using Ctrl-Alt-Del, then logged in again.
Plasma started up but was still frozen (except the clock widget now
showed the updated time). I tried the same thing again, with no
difference.
Doing it a third time would indicate insanity, so this time I switched
to another console (Shift-Alt-Fn), logged in as root and tried a
'telinit 3'. The DE disappeared, I ran 'telinit 5' and the DE didn't
come back. However I now had a GUI cursor on my root console window, so
presumably Xorg was running even though some component of KDE was not.
I rebooted.
