For reasons that I do not understand, the xfce indicator applet has stopped working. It's not visible, so I cannot see thinks like the wireless applet.
I can't find anything from searching the net.
I suspect that it has something to do with dbus.
Perhaps it's related, but whenever I choose to shutdown or restart, it now goes back to the GDM login screen instead. I've had this problem before on earlier Ubuntu distros, but I don't remember how to fix it.
