It looks like this is very much related to the situation in bug 490081.

Logout etc. work fine on my home setup, with laptop connected to one external screen, HDMI.

But, at work with Thunderbolt 4 dock (USB-C + Displayport) dual screen setup, the 2nd display remain dark 50-70% of the reboots. And also logout/shutdown/etc. do not work. But on some occasions the exit functions work OK.

For example today:
Boot #1:
1. Log into Plasma session
2. Observe 2nd screen dark
3. killall kwin_wayland
4. Observe picture on both screens
5. Move mouse to 2nd screen -> 2nd screen goes black
6. Application Menu -> Reboot -> reboots

Boot #2
1. Log into Plasma session
2. Observe 2nd screen dark
3. Disconnect and reconnect TB4 dock data connector
4. After a while both screens on, but in wrong order
5. Reorder screens
6. 6. Application Menu -> Log out -> NO EFFECT

Per my recent findings, these actually are not related. The logout/shutdown/reboot dialog works sporadically.

It worked fine on my home setup (laptop display + HDMI external monitor) this morning, and worked once at office with my work setup: laptop + TB4 dock + 2 screens.

Later in the day it did not work at my office, and now it does not work at home, either.

I experience similar problems. Session doesn't end when logging out, leaves a blank screen with the mouse cursor. I'm using X11, happens with and without the external screen attached.

Using KDE neon with Plasma 6.1.2, problems started after an upgrade to 6.1.0.

Can I have some non-truncated logs.

Sure, can you provide the needed commands / env variables / other stuff needed?

I am not sure if this is very specific to KDE Neon, or particular hardware.
I have another system running openSUSE  Tumbleweed + Plasma 6.1.2 and there's no issue with logout.

I also see this in my Fedora 40  kde X11 , I notice none of the process die 
and also other reports https://bugzilla.redhat.com/show_bug.cgi?id=2290894

also use gdm instead sddm doesn't help

@David:
I can provide the logs, if I could have the needed commands / env variables / other stuff needed for producing them.

from a clean boot, log in, try to log out, run:

"journalctl --user -b"
