Ok, for curiosity, i disabled wifi, set it to be started manually only, left ethernet to
be started automatically. I shut down the computer, leaving the ethernet cable plugged in
and started up the computer. journalctl reports:

Process 1298 (sddm-greeter) of user 988 dumped core.
As far as I can tell, it does the same thing. SDDM will not start, so the system hangs,
does not present a login screen and does a core dump.
So, basically, I need to keep the ethernet cable unplugged until logged in. The wifi can
remain automatic or manual, makes no difference.
Ideas on this?
