kwin/plasma does not start with wayland x11 backend on Devuan.
STEPS TO REPRODUCE

2. Select "Plasma (Wayland)" as session in display manager
3. Login
OBSERVED RESULT
Session aborts with:
% cat ./.local/share/sddm/wayland-session.log
not a reply org.freedesktop.locale1 QDBusMessage(type=Error,
service="org.freedesktop.DBus", error
name="org.freedesktop.DBus.Error.ServiceUnknown", error message="The name
org.freedesktop.locale1 was not provided by any .service files", signature="s",
contents=("The name org.freedesktop.locale1 was not provided by any .service
files") )

martin@om:~$ date
Do 8. Jul 08:58:17 CEST 2021
EXPECTED RESULT
Session starts.
WORKAROUND / SOLUTION
Install "kwin-wayland-backend-drm" and have it use the DRM backend.
SOFTWARE/OS VERSIONS
Linux/KDE Plasma: 5.21.5 on Devuan Ceres (their Debian Sid) with Linux kernel
5.10.0-8-amd64 (which is 1:1 from Debian)
KDE Plasma Version: 5.21.5
KDE Frameworks Version: 5.83
Qt Version: 5.15.2
Devuan runs elogind as a systemd-logind replacement (with CGroups V2 already).
Init system is Runit.
ADDITIONAL INFORMATION
I have no idea whether this is really a bug in Plasma/KWin. Maybe the KWin
Wayland X11 backend is not supposed to work, and the distribution should
install the DRM backend by default. However, if the X11 backend just does not
start due to "org.freedesktop.locale1" (systemd-localed) not being available,
it would be great to see a fix for that uses other means like "locale" to
access localization information. I have no idea whether not finding that DBUS
interface is just a warning or whether it causes to X11 backend to abort, thus
causing KWin not to find any backend since no other backend was installed at
that time.
Please advise.
I am happy that I can run Plasma on Devuan.
