How do I disable Unity in 13.04?

Question

I'm using Xfce most of the time, but Unity keeps popping up even in my Xfce-Session. So I deactivated the Compiz-Plugin in ccsm, because that worked well in 12.10. But now with 13.04 as soon as I relog into my session, the plugin is active again.

How can I stop this from happening?

I'd rather not remove Unity completely, because maybe I want to try something out once in a while.

If you use XFCE, you should use Xubuntu instead of Ubuntu. It has XFCE preinstalled, so the integration with XFCE is seemless. You can install Unity in Xubuntu too so you can still access Unity sometimes.
