Bug 501433

SUMMARY
If you shutdown your system from the gui or shutdown now, the system will give sometimes give an error with UID 1000 service with a timeout of 2m or 1m30s and before that it will not shutdown, likely.
I have logs at the end.

STEPS TO REPRODUCE
1.  Shutdown/reboot your System from the gui of the application menu.
2.  There is a chance that a USER UID 1000 service error will break out.

OBSERVED RESULT
If the issue happens, then the system will shutdown slowly with a timer of 1m30s or 2m.

EXPECTED RESULT
Quick shutdown in under 2 seconds which I achieve normally.

SOFTWARE/OS VERSIONS
(available in the Info Center app, or by running `kinfo` in a terminal window)
Linux/KDE Plasma: Arch Linux
KDE Plasma Version:  6.3.3
KDE Frameworks Version:  6.11.0
Qt Version:  6.8.2

ADDITIONAL INFORMATION
This issue has been happening even when I used to use debian with kde plasma and I recently switched to arch linux, but it also has this error. When I shutdown normally, there is a chance that the system will show the UID 1000.service stop job error and will slow down the boot to a ridiculously slow time.

One user in github pointed out that it's a bug with kde plasma so I came here in the kwin section. The error he pointed out was plasma-kwin_x11.service: State 'stop-sigterm' timed out. Killing.

One user in arch linux forums pointed out that-

kwin_x11 (the window manager) doesn't terminate, even though the X11 server is gone.
dr. konqi doesn't kick in (this was also an issue because it kept the session open/renewed it/whatever)

I tried posting about this on arch linux-
https://bbs.archlinux.org/viewtopic.php?pid=2231316#p2231316

Also created an issue about this in github sddm-
https://github.com/sddm/sddm/issues/2058

Here are the logs, they are a bit old but they are what I have right now.
