Yes I did reboot and tried several times. On one reboot I logged in as Gnome and was successful then tried KDE withe the same as earlier results.

The black screen is plasmashell not starting or crashing.
To see the crash output:

codedumpctl info plasmashell

It is best to use codedumpctl gdb plasmashell it will download a bunch of files so the crash trace is informative, otherwise it is just vague.

Looking at the log, could be useful too:
journalctl -u plasmashell.service -b

Thanks for the info. I have solved the issue by starting the system in X11 and examining the differences to Wayland (I was guessing it was a graphics issue) and it turned out to being a refresh rate issue. I have been a Windows technician for 30+ years and Linux is new to me (only being a user for about 12 months and loving it.) I have to get better at the shell.

Cheers

Drivers don’t easily tell whether a particular refresh rate/resolution is really supported.

If you still had a cursor that’s plasmashell, if nothing is responding that’s kwin (the compositor) that failed to start.

Thanks for the info, good to know.
