I have just upgraded from 11.10 to 12.04 and have the same result. When I select to boot in normal mode, the login screen (that has wrong - low - resolution ) freezes with mouse pointer in the center and keyboard not working. When I shut off the computer with the power button and try to boot in recovery mode, I have a lot of error messages, and then the computer freezes in text mode. When I boot a previous version of Ubuntu, I can actually log in (although with the login screen and desktop having wrong resolution), but all icons are missing and the windows have no captions and borders. I have to add that in 11.10 I did not use Unity (I installed session fallback and used Gnome 2). And there is no Internet connection. I would call this a huge shame for Ubuntu. Nothing like this ever happened to me for 20+ years of using of Windows. It looks like Ubuntu was in a rush to release v.12, so they could not afford testing how the upgrade works. Shame.
