Cannot log in to Unity - black display with cursor

[James Ferguson]

Unity 5.8.0-0ubuntu1

Did an apt-get dist-upgrade this morning (2012-03-26) and rebooted (in a dock w/monitor). Login greeter appears as normal, but on login the screen was blank, and on the laptop screen (expected it on the external montitor).

Unity-2D works (running that now), Xorg.0.log.old is the relevant file - I'll attach it if it's not already there. It had:

[ 592.542] (EE) intel(0): [DRI2] DRI2SwapInterval: bad drawable
[ 592.542] (EE) intel(0): [DRI2] DRI2SwapBuffers: bad drawable

many times.

I tried killing Xorg and logging in again - same deal. Also tried removing laptop from the dock but got the same black screen with mouse pointer. Unity 2D worked fine.
