Bug ID: 476534
Summary: Overriding D-Bus services does not work automatically
using install-sessions.sh
Classification: Developer tools
Product: kdesrc-build
Version: Git
Platform: Compiled Sources
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: mp...@kde.org
Reporter: putr...@gmail.com
Target Milestone: ---
SUMMARY
In the upstream dbus-daemon session.conf file [1],
`<standard_session_servicedirs />` is placed above all of the
`<includedir>session.d</includedir>` type stuff, so the
`<servicedir>/opt/kde-dbus-scripts/services</servicedir>` part that is added by
`install-sessions.sh` will be below the standard (system and user) directories.
This means that for a system that has KDE Plasma installed both through the
distro as well as kdesrc-build dbus-daemon will pick the version installed
through the distro rather than the one provided by kdesrc-build, as per the
documentation [2].
In my case this is a problem when trying to logout/shutdown/reboot with the log
out greeter/screen enabled in a Plasma 6 session from kdesrc-build alongside
Plasma 5.27.9 from the Arch repos, since DBus will load the Qt5 version of the
greeter from the repos but with the QML2_IMPORT_PATH environment variables and
such set so that it tries to load the Qt6/KF6 versions of things instead
(specifically it failed at loading
`~/kde/usr/share/plasma/look-and-feel/org.kde.breeze.desktop/contents/logout/Logout.qml`).
To work around the logout greeter problem I copied the
`org.kde.LogoutPrompt.service` file to `.local/share/dbus-1/services/`, that
makes the greeter in the Plasma 6 session work.

STEPS TO REPRODUCE
1. Compile and install a Plasma 6 session via kdesrc-build
2. Login into the new session
3. Try to logout/reboot/shutdown with the logout screen/greeter enabled
OBSERVED RESULT
The screen just blurs, but no buttons or anything else appear.
EXPECTED RESULT
The options to logout, reboot, shutdown and so on should appear.
