I guess I wasn't as clear as I could be in my posts - I was using 11.04 and 11.10 under the fallback mode. That's what made it easy for me. I started with Ubuntu 9 something, and upgraded to 12.04 from 11.10 in the Gnome fallback. This worked for me.
My last question on this thread is: will Ubuntu continue to provide the Gnome fallback desktop, or is that going away? If it's available in the future I can live with most of the lingering problems.
