I'll doublecheck, but I swae the last couple of Xubuntu installs seemed 
to autoenable compositing (ie. I've gone to turn it on as a post-install 
desktop config, and found it already active).

(hrm, now I think about it, all of those installs have been 
post-installation additions of the XFCE packages, to a system that was 
running Unity (with 3d stuff enabled) previously.. I wonder if it's 
transferring settings from Unity?)
