I would love to use UNR instead of unity, I think it's much better. I first found it in 10.04 netbook but I don't want to do a fresh install of that it's way to much work.
I have a new problem, I can't choose what interface I want like, unity, UNR or normal desktop (on the log in screen). It may be sorted in the final release but, now it's a big problem.
Everything works now, and it's stable, big thanks!
