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."

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.
