This happens for me from time to time with 22.04.
I keep a text file in the Desktop-folder accessible from a terminal (as
stated above with ctrl-alt-f1) with the below contents.

Before I fire up the big guns I give the DE and WM some time to start up on
its own. If not, I use this:


<code>

CLI-commands to restart crashed DE or WMs:

KDE:
killall plasmashell; kstart5 plasmashell

Xorg:
systemctl restart display-manager
</code>


The DE restart command usually solves the problem.
When logged on, subsequent restarts brings stuff up normally as expected.
YMMV of course.
