To each his own, but I love eye candy. When I heard that you could get the 3D Xgl and Compiz environment running on Ubuntu/Kubuntu dapper (my default distribution), I immediately searched the web for instructions. Most of the instructions take a reasonably timid approach, which gets your 3D environment running in a test console (the second display, or :1). I'm more adventurous, however, and I immediately went for a total replacement. What follows are instructions for doing the same.
