Bug ID: 503120
Summary: Plasma session with Xwayland disabled exits
unexpectedly when `systemctl --user daemon-reload` is
run
Classification: Plasma
Product: kwin
Version: 6.3.4
Platform: Ubuntu
OS: Linux
Status: REPORTED
Severity: crash
Priority: NOR
Component: wayland-generic
Assignee: kwin-bugs-n...@kde.org
Reporter: danielrh+kdeb...@proton.me
Target Milestone: ---
SUMMARY
If Xwayland is disabled, running `systemctl --user daemon-reload` causes the
Plasma session to exit abruptly.
STEPS TO REPRODUCE
1. Disable Xwayland in Plasma, for example by running `systemctl --user edit
plasma-kwin_wayland.service` and adding the following lines in the service file
override:
[Service]
ExecStart=
ExecStart=/usr/bin/kwin_wayland_wrapper
2. Restart the computer and log in via the graphical interface as usual.
3. In a terminal, run `systemctl --user daemon-reload`.
OBSERVED RESULT
The Plasma session immediately exits, closing all open applications and logging
out the user.
EXPECTED RESULT
Running `systemctl --user daemon-reload` shouldn't cause the Plasma session to
exit.
SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Kubuntu 25.04
KDE Plasma Version: 6.3.4
KDE Frameworks Version: 6.12.0
Qt Version: 6.8.3
ADDITIONAL INFORMATION
Also tested on Fedora Kinoite 42; the same thing happens. The bug does not
occur if Xwayland is enabled.
I couldn't manage to get a backtrace; as far as I can tell, the Plasma shell
seems to exit normally (technically not crashing), just under circumstances
when it shouldn't be exiting.
