Log output from journalctl

SUMMARY
I am running KDE Plasma desktop on Debian Bookworm on a Lenovo ThinkPad P1 with
NVIDIA Quadro P1000 graphics. Sometimes when I resume from suspend when plugged
into a HP USB-C Dock G5 with two displayport monitors attached X11 crashes (as
well as all the other running applications) and instead of resuming my previous
session, I am presented with a new login screen.

Today, the first resume worked, then I suspended, plugged into my dock and the
resume failed.

I have asked for advice on the Debian User Forums here:
https://forums.debian.net/viewtopic.php?t=154460


STEPS TO REPRODUCE
1. Plug laptop into dock using USB-C
2. Open lid

OBSERVED RESULT
New login screen. There are a few segfaults from KDE components, e.g. kscreen, kwin, plasmashell.

EXPECTED RESULT
Existing session unlock screen.

Yeah, when the X server crashes, it takes everything else down with it. Please report this issue to the X11 folks.
