This happens to me on every boot now as of yesterday's updates. Video card is a Radeon 3850, but compiz still appears to be running, just without the Unity environment. There's just Nautilus on the desktop, and startup items do load. To get anything done, I have to start apps with DISPLAY=:0 from another login.
