The name org.freedesktop.Notifications was not provided by any .service files

Últimamente estoy usando mate-desktop por que me parece una muy buena alternativa a usar Gnome3 Cuando intento arrancar gfuw ( Gtk Uncomplicated FireWall ) me salta este error y gufw, no activa el firewall.

name org.freedesktop.Notifications was not provided by any .service
name org.freedesktop.Notifications was not provided by any .service

Buscando he visto en https://bbs.archlinux.org/viewtopic.php?id=75078 que es debido a que falta el paquete notification-daemon. En mate-desktop tenemos el paquete mate-notification-dameon por lo que hay que instarlo:
[shell]
sudo apt-get install mate-notification-daemon[/shell]
y al siguiente arranque de sesión, debería arrancar, si no, podemos ejecutarlo manualmente con el comando
[shell]/usr/lib/mate-notification-daemon/mate-notification-daemon[/shell]
y ya tenemos gufw funcionando bien
