I've made progress identifying the problem. This is an intel driver problem. The latest ppa driver for xserver-xorg-video-intel ppa.8.2 has been reported to work.
However attempting to use synaptic to install the natty package produces a broken package not surprisingly. The latest intel video drivers on oneiric appear to produce a segmentation fault in geis_init.
I upgraded one computer to oneiric but until compiz loads I cannot proceed with the upgrade. I would include the compiz log on install but it is virtually identical to the one which refers to Unity 3D not working on a Quadro NVS
