I ran the test this evening while I was remotely connected to the
machine from a different machine. When KDE stuck, I checked the
Xorg log from the other machine, without switching consoles on the
machine with the problem. The log ended like this:
[261624.860] (II) AIGLX: Suspending AIGLX clients for VT switch
[261624.925] (II) systemd-logind: got pause for 13:65
[261624.925] (II) systemd-logind: got pause for 13:69
[261624.925] (II) systemd-logind: got pause for 226:0
[261624.925] (II) systemd-logind: got pause for 13:64
[261624.925] (II) systemd-logind: got pause for 13:66
[261624.926] (II) systemd-logind: got pause for 13:68
[261624.926] (II) systemd-logind: got pause for 13:67
So, no, I hadn't tried to switch consoles when those messages
appeared.
That's strange because those lines are only caused by a VT switch as it
says...

Well, I'm certainly seeking hints. The VNC session got me to a blank
screen image. I opened an xterm on it and ran startx.
You what? You ran startx from within an X session?
