Description Matt Fagnani 2021-03-14 16:49:27 UTC 
SUMMARY

When I've logged out of Plasma 5.21.2 and earlier on Wayland in a Fedora 34 KDE Plasma installation, kded5, kwalletd5, drkonqi, and sometimes xdg-desktop-portal-kde have aborted with errors like "The Wayland connection broke. Did the Wayland compositor die?" likely because kwin stopped before they did.

I've usually selected Sleep in sddm after logging out then resumed the system later. When I've logged in to Plasma on Wayland after logging out since updates on 2021-3-11 which included KF 5.80.0 and systemd-248~rc2-5.fc34, Plasma hasn't started properly with a black screen being shown for up to a minute or so. After that I switched back to sddm on VT1 or sddm appeared again. The journal showed messages that the drkonqi crashes still remained like "user@1000.service: Unit process 8094 (drkonqi) remains running after unit stopped." Those were followed by systemd errors like "user@1000.service: Failed to attach to cgroup /user.slice/user-1000.slice/user@1000.service: Device or resource busy" and "systemd[1]: Failed to start User Manager for UID 1000."

Mar 13 20:20:50 sddm[913]: Could not setup default cursor

Plasma hasn't started properly 10 times after logging out in this way since 2021-3-11 which is most of the time I've tried to log in. Plasma also failed to start after logging out and not selecting sleep in sddm. Plasma started normally the next time after Plasma failed to start as above. 


STEPS TO REPRODUCE
1. Boot a Fedora 34 KDE Plasma installation updated to 2021-3-14 with updates-testing enabled.
2. Log in to Plasma 5.21.2 on Wayland
3. Log out
4. Log in

OBSERVED RESULT
Plasma on Wayland didn't start with a systemd error "user@1000.service: Failed to attach to cgroup /user.slice/user-1000.slice/user@1000.service: Device or resource busy" after logging out

EXPECTED RESULT
Plasma would start normally after logging out.

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Fedora 34
(available in About System)
KDE Plasma Version: 5.21.2
KDE Frameworks Version: 5.80.0
Qt Version: 5.15.2

ADDITIONAL INFORMATION
Plasma started normally after logging out with KF 5.79.0 and earlier. The problem might be in KF 5.80.0.
Comment 1 Matt Fagnani 2021-04-13 01:43:03 UTC 
I've continued to see this problem when I've logged out of Plasma 5.21.4 with KF 5.80.0 and logged in within about 40 seconds. If I logged in again after about 40-60 seconds, then Plasma started normally. When I rebooted or shut down from Plasma, a systemd message like "A stop job is running for User Manager for UID 1000" was shown for 40-60 seconds before the reboot or shutdown happened most of the time. 

I noticed in the KF 5.81.0 changelog for kded https://kde.org/announcements/frameworks/5/5.81.0/ the commit "make kded shut down cleanly during systemd session teardown" https://invent.kde.org/frameworks/kded/-/commit/96aa058b2b70bc19484e649b5bfcbb86d36336ff I changed /usr/lib/systemd/user/plasma-kded.service like in that commit by adding the line PartOf=graphical-session.target

I logged in and out multiple times after that making that change, kded5 didn't abort during logout according to coredumpctl. Plasma started normally each time I logged in again within 10 seconds of logging out. That commit might be sufficient to avoid this problem. kwalletd5 still aborted when logging out, though kwalletd5 appears to just have a dbus-activated systemd service /usr/share/dbus-1/services/org.kde.kwalletd5.service and not a user session one like kded.
Comment 2 Melechtna Antelecht 2023-02-05 22:32:41 UTC 
I can confirm that this issue very much stems from plasma-dbus-run-session-if-needed seeming to have no idea of the dbus session is needed. The best solution I've been able to come too, and I'm apparently not the only one,

https://bugzilla.redhat.com/show_bug.cgi?id=1897717

Is to modify the plasmawayland.desktop in /usr/share/wayland-sessions/ to simply throw out the detector script and just run dbus-run-session instead, then plasma starts normally. So clearly whatever this is doing

drs=
if [ -z "${DBUS_SESSION_BUS_ADDRESS}" ]
then
    drs=dbus-run-session
fi
exec ${drs} "$@"

Doesn't do its job.
Comment 3 David Edmundson 2023-09-29 14:31:58 UTC 
Git commit 6ce8f434139f47e6a71bf0b68beae92be8845ce4 by David Edmundson.
Committed on 29/09/2023 at 16:31.
Pushed by davidedmundson into branch 'master'.

Use systemd to handle more of the shutdown

Previously we killed kwin manually, then tried to exit the session.
This is racey as kwin will close all connections, before systemd has
realised that the session is ending this can cause all apps to restart.

Also closing plasma-workspace-wayland.target is ineffective, closing the
graphical-session implicitly brings down the session more explicitly.
It'll close the other targets and services.
Related: bug 473824, bug 409088, bug 450531, bug 451939, bug 450320

Tested by looking at `coredumpctl list` after a logout and seeing it go from 10 entries of silly aborts restarting without a display server to 3, with different unrelated causes.
