As for the "I thought 12.04 has native tegra3 support" I don't know how clear I can be (I said this a page back) Userland does not care in the slightest about the underlying userland, there is only one thing that really cares about the SoC, and that is the acceleration driver, which by default is not installed.
Thanks now I'm trying again, I first installed the touch recovery.
Just finished upgrading the delete pulseaudio and then restart system.
ok working, after launch I'm try backup and restore.
