See https://wiki.gnome.org/HowDoI/DBusApplicationLaunching and https://wiki.gnome.org/Initiatives/GnomeGoals/DBusActivatable for a description of this key: > Instead of the typical UNIX-style fork()/exec() approach to process creation, > launching an application is done by sending a D-Bus message to the well-known > name of that application, causing a D-Bus activation. > > Starting processes with D-Bus activation ensures that each application gets > started in its own pristine environment, as a direct descendent of the > session -- not in the environment of whatever its parent happened to be. This > is important for ensuring the app ends up in the correct cgroup, for example. So this motivation is not important for us: we launch stuff ourselves better. This fixes warnings during boot: systemd-xdg-autostart-generator[2274]: /etc/xdg/autostart/org.freedesktop.problems.applet.desktop:92: Unknown key name 'DBusActivatable' in section 'Desktop Entry', ignoring.
