> SUMMARY
> When issuing a shutdown or restart from within a Plasma Wayland session,

Same here.
The issue started using the 15.15 kernel. Check with 5.10-LTS seems fine.
Just switching to a new session (strg+alt+F-key) and back immediately successfully stops SDDM.
Operating System: EndeavourOS
KDE Plasma Version: 5.23.3
KDE Frameworks Version: 5.88.0
Qt Version: 5.15.2
Kernel Version: 5.15.2-zen1-1-zen (64-bit)
Graphics Platform: Wayland
Graphics Processor: AMD Radeon RX 5500 XT

I downgraded to kernel 5.14.16 and the issue went away. Shutdown is immediate. I am having the same issue with xorg - https://bugs.kde.org/show_bug.cgi?id=445385 Would you be able to test git master there? f377696bff39e35ae0f7ae6104d8732b3856744e could help address this issue. Otherwise, could you try enabling systemd boot for Plasma and see if it addresses the problem for you? https://invent.kde.org/plasma/plasma-workspace/-/wikis/Plasma-and-the-systemd-boot .

Will that MR be included in 5.23.4? If so, I will let you know if it resolves when it hits the repo next week. Reporting back that 5.23.4 does not fix the issue. (In reply to Jon Voss from comment #11) > Reporting back that 5.23.4 does not fix the issue. I think it is a kwin (compositor bug). Systemd is not able to kill kwin. Thats why it takes time to shutdown. With another display manager there is no delay in shutdown. The problem is caused by SDDM, (In reply to Alberto from comment #13) > With another display manager there is no delay in shutdown. > The problem is caused by SDDM, Anyways I fixed my problem. I am using cinnamon with sddm. I completely removed kde and it works fine. Kde has a lot of bugs and they don't fix it so I switched to cinnamon and it works like a charm. The best way to fix a problem is to file a bug report and if they don't fix it just simply move to a new display manager or a new desktop environment. Cinaamon is much better than plasma and they have dont have serious bugs like kde. Cinnamon is a bit ugly but u can change it if u want. Don't have * For me, this problem was present during approximately two months before 2021-12-11, whcih was when I was utilising Manjaro KDE, and subsequently Rawhide of Fedora Kinoite, and subsequently Rawhide of Fedora KDE Plasma Desktop. This problem did not affect my subsequent and recent installation of Debian 12, although my lack of utilisation of that installation may have been why it did not affect it. Additionally, this problem has not affected my current installation of Rawhide of Fedora KDE Plasma Desktop by version of the installer of Fedora Server that had been submitted from Rawhide. I have not manually installed new drivers since my current installation of Fedora KDE Plasma Desktop, and I have extensively utilised this computer. Consequently, is anybody that is utilising the most new version of their distribution able to verify that this is occurring for them? This bug is also in OpenSuse Tumbleweed I was able to compile git master and it appears this may be fixed there. I haven't tested extensively, but a couple of reboots didn't hang. From my quick debugging session, it appears like sddm is stopped, but then sddm restarts for some unknown reason. Tested on OpenSuse Tumbleweed Krypton (Git) on January 2nd and the problem still is present. The timer can be worked around when the keys for the session are pressed (ctrl + f7 OpenSuse / ctrl + f1 arch). Can somebody report this issue to SDDM developers? SDDM stops X11 and then restarts it for some reason, which causes a hang. kwin_wayland is gone by that time. FTR, with wayland greeter, I can't reproduce the issue. As a workaround you could use [General] DisplayServer=wayland [Wayland] CompositorCommand=weston --shell=fullscreen-shell.so EnableHiDPI=true make sure that you have weston installed, you could also use kwin_wayland Here's the issue in SDDM: https://github.com/sddm/sddm/issues/1476 *** Bug 445385 has been marked as a duplicate of this bug. *** *** Bug 451065 has been marked as a duplicate of this bug. *** I also have this issue with Plasma 5.24.3 on Manjaro, using the wayland session and kernel 5.16 I also have this issue with Plasma 5.24.4 on Arch, using the wayland session and kernel 5.17. I have this issue with Plasma 5.24.4 on Arch with Kernel 5.17.1, on my laptop and my desktop with the same OS. I also have this issue with Plasma 5.24.4 on Arch, using the wayland session and kernel 5.17.4 (In reply to steve from comment #28) > I also have this issue with Plasma 5.24.4 on Arch, using the wayland session > and kernel 5.17. Edit: I have found the most convenient workaround right now is to logout the user before shutting down/rebooting. What was the real problem with this? Why was this kernel related? I haven't seen anything relating to the real problem, just work around so things don't take long to shut down. We are seeing the same thing (Slow SDDM shutdown) and worse on CentOS Stream 8. All of it is fine with an older kernel, but the newer kernel is having issues. Note: We are seeing a blank screen on SDDM startup. If you use a different desktop manager, then ksplash is blank. And then if you lock your screen, you never get a password prompt to unlock it.

I think I can confirm this workaround: 5 s shutting down (once logged out after 2 s) vs 3 minutes waiting. I can confirm that this bug still exists for me, but that the workaround with logging out before shutting down works. My system is Plasma 5.26.2 on Arch, using the wayland session and kernel version 6.0.6-arch1-1 (64-bit) The upstream bug was closed without a general solution on Jun 15. FWIW I keep experiencing it on Plasma 5.26.2 Wayland on openSUSE TW with kernel 6.0.6 and systemd-boot. The relevant part of journalctl is the following: ``` 16:35:11 systemd[1]: user-1000.slice: Consumed 2min 4.592s CPU time. <---------------------------------------------------------------------------------------> 16:36:40 systemd[1]: display-manager.service: State 'stop-sigterm' timed out. Killing. 16:36:40 systemd[1]: display-manager.service: Killing process 2011 (sddm) with signal SIGKILL. 16:36:40 display-manager[1989]: Starting service sddm 16:36:40 systemd[1]: display-manager.service: Main process exited, code=killed, status=9/KILL 16:36:40 systemd[1]: display-manager.service: Failed with result 'timeout'. 16:36:40 systemd[1]: display-manager.service: Unit process 8024 (Xorg.bin) remains running after unit stopped. 16:36:40 systemd[1]: Stopped X Display Manager. 16:36:40 systemd[1]: display-manager.service: Triggering OnFailure= dependencies. 16:36:40 systemd[1]: Requested transaction contradicts existing jobs: Transaction for plymouth-quit.service/start is destructive (srv.mount has 'stop' job queued, but 'start' is included in transaction). 16:36:40 systemd[1]: display-manager.service: Failed to enqueue OnFailure= job, ignoring: Transaction for plymouth-quit.service/start is destructive (srv.mount has 'stop' job queued, but 'start' is included in transaction). 16:36:40 systemd[1]: Starting Show Plymouth Reboot Screen... 16:36:40 systemd[1]: Stopping User Login Management... ``` Does the proposed workaround in comment 23 only work for sddm git master? Is there any known ETA for a new release? openSUSE TW comes with SDDM 0.19.0-7.1 and despite setting wayland as the display server, sddm keeps sticking to X11. The problem is that SDDM needs a new release with the fix in it. I've talked to the SDDM folks and they're going to try to do one soon. I had the same issue on Arch, installing sddm-git from AUR fixed the problem. I confirm that issue on Plasma 5.27 on Wayland on Manjaro. With X11 shutdown is quick, with Wayland it's 1,5 minute delayed. I also have this problem with Plasma 5.27.4 on Tumbleweed, on a computer running nouveau and on another with the nvidia driver. Normal shutdown with X-11, 90 second delay with Wayland. Wayland runs perfectly in other respects. I'm using kubuntu 23.04 with backports (plasma 5.27.6) . I get this logout hang with kernel 6.4 (Liquorix) but not with the distro's 6.2 kernel. Using kernel 6.5.4 (in openSUSE) and similar issue. Each time I shutdown, applications are closed, but a black screen remains forever and system doesn't switch off. Hi, I have the same issue and I believe the problem started after a recent kernel update. My versions: Operating System: Kubuntu 23.04 KDE Plasma Version: 5.27.4 KDE Frameworks Version: 5.104.0 Qt Version: 5.15.8 Kernel Version: 6.2.0-37-generic (64-bit) Graphics Platform: Wayland (In reply to Josh from comment #42) > Hi, I have the same issue and I believe the problem started after a recent > kernel update.

When this happens, hit the Escape key and you'll be able to see what exactly is causing shutdown to be slow. If it's SDDM, then make sure your distro has SDDM 0.20, which fixed the issue If it's not SDDM, then the issue is caused by something else hanging on quit. |
