zh-CN:D-Bus Template:Article summary start Template:Article summary text Template:Article summary end 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.


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) will do the same. Make sure that your ~/.xinitrc is based on the skeleton file /etc/skel/.xinitrc.
