D-Bus
D-Bus is a message bus system that provides an easy way for inter-process communication. It consists of a daemon, which can be run both system-wide and for each user session, and a set of libraries to allow applications to use D-Bus.
Installation
D-Bus is enabled automatically when using systemd because dbus is a dependency of systemd.
Starting the user session
gnome-session, startkde and startxfce4 will start a D-Bus session automatically if one is not already running. The skeleton file for ~/.xinitrc
(/etc/skel/.xinitrc
from xorg-xinit) will do the same. Make sure that your ~/.xinitrc
is based on the skeleton file /etc/skel/.xinitrc
.
Debugging
d-feet is an easy to use D-Bus debugger GUI tool. D-Feet can be used to inspect D-Bus interfaces of running programs and invoke methods on those interfaces. See its homepage for more info.
