Ugh. Found the cause. The ubuntu-desktop package depends on lightdm but it doesn't depend on any greeter. So upgrading will pull in lightdm, replace GDM but have no greeter installed. What is supposed to happen then is failsafe X starts and prompts you to fix the error, but that doesn't work either.

Solution is to make ubuntu-desktop depend on unity-greeter.
