Abilitare le screenlet in Kubuntu Hardy

Dopo aver installato la nuova versione della distribuzione Kubuntu 8.04 ho installato i driver per la scheda video (NVIDIA) del mio Toshiba, abilitato compiz, e tentato di abilitare le screenlet, ma non riuscivo ad avviare lo screenlet manager.
Provando ad avviare da console sono riuscito a leggere le motivazioni di tale problema.

Sembra essere in esecuzione kde
True
Unable to load 'MainMenu' from /usr/share/screenlets/MainMenu: No module named gmenu
Error while loading screenlets metadata for "MainMenu".
Orca is required to use this Screenlet
You need Gtkmozembed to run this Screenlet , please install it

Il problema è dunque dato dalla mancanza di dbus-launch, ma fortunatamente tale problema può essere facilmente risolto tramite

sudo aptitude install dbus-x11

Fatto ciò lo Screenlets Manager è tornato a fare il suo lavoro.
A presto.
