Alternatively, making the notification server as a D-Bus service, the notification server can be launched automatically on the first call to it. For example, after installing the notification-daemon package, add the following configuration to D-Bus services directory (/usr/share/dbus-1/services or $XDG_DATA_HOME/dbus-1/services):
org.freedesktop.Notifications.service
[D-BUS Service]
Name=org.freedesktop.Notifications
Exec=/usr/lib/notification-daemon-1.0/notification-daemon
