I also had this bug on a thinkpad x220 i7 sandy bridge tablet with integated intel graphics after doing an upgrade from 10.10 to 12.04 beta today Mar 26.
I ran "DISPLAY=:0.0 unity --reset" from vt2 and after a bunch of messages unity 3d started up correctly and continued to work after a relog. Though in addition to warning messages there was a segfault when I ran --reset. Compiz: 1:09.7.2-0ubuntu1 Unity: 5.8.0-0ubuntu2 (some successful messages) ...
