Public bug reported: After upgrading to 12.04 (beta), my Apple cinematic display hasn't been working correctly. Booting and splash screen works normally, but at the end of the boot the screen goes black. This doesn't happen all the the time -- I managed to boot correctly once, another time I got to gnome login before then screen froze.
My current workaround is to boot older kernel (the one used in 11.10, 3.0.x). Since this is my work machine, I haven't had time to debug more thoroughly, so I don't know if the problem lies in nvidia drivers, kernel or x.org.
