DBus Activation for apps in prefix

On my systems I noticed that some services like kglobalaccel are not automatically started when logging into the system. This is on the one hand rather annoying on the other it could indicate a bug in our setup. So this morning I started to look into the issue with kglobalaccel.

Kglobalaccel is a service which is supposed to get started through dbus. My installation prefix is “/opt/kf5″ and so the service file gets installed to “/opt/kf5/share/dbus-1/services/org.kde.kglobalaccel.service” – that looks fine. After some investigation I figured out that dbus-daemon looks in $XDG_DATA_DIRS as a search path. Our startkde script adjusts $XDG_DATA_DIRS to include /opt/kf5/share before launching the dbus daemon. But when looking at the environment of the running dbus-daemon one could see the problem: it doesn’t use the set environment variable. The reason is obvious: dbus is nowadays started before the desktop environment gets started.

This means D-Bus doesn’t know where to look for the service files. To fix this create a file “/etc/dbus-1/session.d/plasma-next.conf” with the following content (adjust path as needed):

<!DOCTYPE busconfig PUBLIC "-//freedesktop//DTD D-Bus Bus Configuration 1.0//EN"
 "http://www.freedesktop.org/standards/dbus/1.0/busconfig.dtd">
<busconfig>
  <servicedir>/opt/kf5/share/dbus-1/services/</servicedir>
</busconfig>

Save, logout, login and kglobalaccel and others should auto start.

    1. we are working on it, but to my understanding of the documentation it’s not possible to update where dbus has to look for session files through it.
