Comment 10 for bug 748137

Add the daily build PPA from here: https://launchpad.net/~unity/+archive/daily. Fully update your system. Log into unity session. If nothing comes on screen, try logging out again. You will eventually see unity interface. Also be prepared to run the command: compiz --replace for crashes.

But take a note that your eyes will bleed because unity will be extremely laggy. I don't know what is causing it. So I purged the PPA and now I am happy with classic desktop.

Once this fglrx patch lands in next compiz release in natty, I will file a separate bug for laggy unity.
