Bug Description

Currently the metacity/panel setup of ubiquity-dm provides for a terrible transition when booting the Ubuntu GNOME live cd.

It would be very nice and much more consistent if we could use a gnome-shell session mode for this.

The gnome-shell side would involve creating a json file that defines the limited UI of the session, much like what is done for gdm login screen and gnome-initial-setup. This json would be shipped by ubiquity.

ubiquity-dm would then need to launch `gnome-shell --mode=ubiquity`.

How well does Gnome-Shell perform without 3D graphics drivers installed? Since the installer CD doesn't load those (NVIDIA, ATI).
How well does it perform in Qemu?

I believe I have experienced minimal gnome-shell with fedora installer, which well failed to display correctly in Qemu-kvm.

Despite above concerns, this is for Ubuntu-Gnome team to investigate / consider / implement.

3D drivers are loaded where available from what I can tell, this means intel, nvidia and amd would be using the open source drivers which work perfectly fine with gnome-shell. Vbox and Vmware both have 3D out of the box, so really its just Qemu that is going to fallback to LLVM.

gnome-shell can be quite slow on a single low powered core when using software rendering, but should be still usable and render correctly. I havent actually tested qemu myself however.
