[Bug 1214732] Re: Use gnome-shell as window manager in ubiquity-dm (Ubuntu GNOME)

[Tim]

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.

Title:
  Use gnome-shell as window manager in ubiquity-dm (Ubuntu GNOME)

Status in “ubiquity” package in Ubuntu:
  Incomplete

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`.
