That's my experience so far on the 2011 Mac Mini with i7 & AMD Radeon HD 6630M graphics. I was able to install via the ubuntu-11.10-alternate-amd64.iso. But I can't get x to start.

I've posted a couple of pleas for help here ( but no one seems to be getting this to work. Or at least, they're not responding to my posts.

This seems like a shame. I'd love to get ubuntu working on this little beast. But right now I'm dead in the water.

What should be my next step? A bug report?
