This command frees you from the annoying popups in the right upper corner, everytime a mail, IM or whatever is recieved
sudo mv /usr/share/dbus-1/services/org.freedesktop.Notifications.service /usr/share/dbus-1/services/org.freedesktop.Notifications.service.disabled
to turn it on again, just run this
