When you run kwin_wayland --replace, Xwayland will go down together with kwin. Unfortunately, ksmserver still requires X11, so it also goes down after running kwin_wayland --replace, i.e. the shutdown screen may not work as desired. Hopefully, this will be fixed with crash resilience changes. Sounds like the proper fix would be for ksmserver to not require x11; as there will never be a time when kwin_wayland will never crash. Could bug #448517 be related to this one? (In reply to Nate Graham from comment #2) > Sounds like the proper fix would be for ksmserver to not require x11; as > there will never be a time when kwin_wayland will never crash. I noticed that Flatpak apps using X11 also hang indefinitely. Deleting /tmp/.X11-unix/X1 (and restarting them) resolves that. Just having ksmserver not depend on X11 seems not enough: kwin_wayland might need to be able to restart XWayland. P.S. Is there a workaround? Can I somehow restart XWayland manually and make Flatpak apps and the logout dialogue work again? Created attachment 148011 [details]

Any helpful relationship? Xwayland crash in gdm as screen off and touchscreen detach. https://bugs.launchpad.net/oem-priority/+bug/1948894 The content of attachment 148011 [details] has been deleted

No. It's sole job is an X11 session manager.
Bigger question is why it being missing prevents shutdown, it shouldn't. How are you shutting down exactly?
Any method: click buttons in Kickoff or activate any of the session items from KRunner. *** Bug 454071 has been marked as a duplicate of this bug. *** Does installing xorg-xwayland-git from AUR fix this issue?

The bug persists with xorg-xwayland-git from AUR. Do you know the exact steps that always trigger the issue for you? 1. start Plasma Wayland session 2. run 'kwin_wayland --replace' with krunner (In reply to Patrick Silva from comment #19) > 1. start Plasma Wayland session > 2. run 'kwin_wayland --replace' with krunner You are correct, the issue is NOT fixed by installing xorg-xwayland-git the steps above result in the issue described in OP. *** Bug 456601 has been marked as a duplicate of this bug. *** A possibly relevant merge request was started @ https://invent.kde.org/plasma/plasma-workspace/-/merge_requests/2364 A possibly relevant merge request was started @ https://invent.kde.org/plasma/plasma-workspace/-/merge_requests/2368 A possibly relevant merge request was started @ https://invent.kde.org/plasma/plasma-workspace/-/merge_requests/2369 Fixed by David Edmunsdon with https://invent.kde.org/plasma/plasma-workspace/-/commit/c593897b80c9962c575f10391cabe4cf8fbc1fe0 in Plasma 5.27! Can reproduce on Plasma 6 beta. STEPS TO REPRODUCE 1. use Wayland session 2. restart kwin_wayland by running 'kwin_wayland --replace' with krunner 3. invoke the logout screen by pressing ctrl+alt+del 4. choose Log Out, or Restart, or Shut Down Result: nothing happens Operating System: Arch Linux KDE Plasma Version: 5.90.0 KDE Frameworks Version: 5.246.0 Qt Version: 6.6.1 Graphics Platform: Wayland *** Bug 477911 has been marked as a duplicate of this bug. *** A possibly relevant merge request was started @ https://invent.kde.org/plasma/plasma-workspace/-/merge_requests/3672 Git commit 015652168e7e2949efde4ab2707ac72ef934ce96 by David Edmundson. Committed on 12/12/2023 at 22:32. Pushed by davidedmundson into branch 'master'. plasma-shutdown: Continue on ksmserver errors If ksmserver fails to respond to a shutdown request it is more important to continue the user's request of shutting down than it is to bail out. This comes up more often the legitimate case wayland where an xwayland crash would leave ksmserver not running, but does not log the user out. We want to move in the direction of ksmserver being optional on wayland.
