I donít understand..

When I installed Ubuntu Natty beta 1 on my Asus U35JC laptop I got Unity by default(and it worked fine). When running live Ubuntu daily(downloaded yesterday) on it I get Unity(working). But after installing it on the hard drive I get a message telling me I donít have the hardware to run Unity and it falls back to Ubuntu classic. This is after the first run.

When I log out I donít get the options in the dropdown box to choose Unity(its not there). I installed Unity 2D(qt) but also that option is missing in the login screen.

The laptop have to gpu (navidia and Intel), I have disabled the navidia gpu. The Intel one is good enough to run 720p films, and as I wrote above unity worked i beta 1 and in live mode.

Any tips?

Thanks
