Is Ubuntu now building with these patches to make the new GDM support
MultiSeat?

The new GDM supports the Init, PreSession, PostSession, and PostLogin
scripts just like the old GDM 2.20 did.  So, as long as you are using
these interfaces, it should work.

If you run into any issues getting this working in your setup, let us
know.  I'm sure others who might have issues would be interested to
hear how you get this working, especially if you find any gotchas.
