You should check on your working system what you get. I don't
have any of those types of pause messages.
I suppose you could try with selinux disabled as this appears to
be a system-wide issue as opposed to a use configuration issue.
SElinux is disabled.
On the working system, the above messages are followed by
[ 72483.987] (II) AIGLX: Resuming AIGLX clients after VT switch
I'm not switching consoles. I haven't yet reached the opportunity
to do so when the system hangs and the black screen appears. After
that, yes, I can and do switch to a text console so I can kill the
hung KDE session.
Searching for references to that AIGLX message, I find several
reports, some going back a few years. The solutions are things like
installing a different GUI so they aren't very helpful.
But it certainly does look like the systemd-logind pause is stuck
and could be the cause of my problem.
Have I mentioned that I installed TigerVNC on the system, then
connected from a different one? In that situation, KDE starts fine.
The problem is only on the main screen.
