I'm using Ubuntu Gnome 13.04. I love that Empathy's messaging integrates with the gnome-shell. I want to chat over facebook.

However, Ubuntu Online Accounts is not working for facebook messaging (it connects, but then Empathy thinks it has failed to connect), and Empathy will not allow me to connect to facebook in any other way (I sucessfully connected using fedora 19 - however, fedora does not have good hardware support for my laptop, so I need ubuntu here.

Truth be told, I don't really care for ubuntu online accounts, and I'd prefer to simply use xmpp (or Gnome online accounts if that is not possible). How would I go about doing that?
