dconf-service - Man Page
D-Bus service for writes to the dconf database
The dconf-service program provides the ca.desrt.dconf name on the session or system bus. Users or administrators should never need to start the service, as it will be automatically started by dbus-daemon(1) whenever an application tries to write settings.
Reading values from the dconf database does not involve the service; it is only needed for writes. The service is stateless and can exit freely at any time (and is therefore robust against crashes).
