Then I tried to suspend; resume with monitor attached. Didn't work
either - see second log file.
(One thing I'm wondering: I *am* using the same brand and type of
monitor, connected to the same brand and type of dock, at *different
places*. Could that be the culprit? I.e. having used the LG
Connecting the dock without monitor is fine. Then connecting the DisplayPort
connector:

Might be a Wayland bug after all:

connected ("usb 1-4: new high-speed USB device number 53 using

I can reproduce this issue, too.
When plug in the dock(with HDMI 4k monitor), the screen freeze and

Un-plug the dock, everything works again.
BTW, I found gnome-shell runs in 100% while the issue happened, and un-
plug the dock
