I'm not sure. Ubuntu doesn't use GDM by default. LightDM happens to do the right thing, and leaves the layout correct when it starts the user session, which is why the Ubuntu bug mentions autologin.
But autologin is a bit of a red herring, because the reproduction steps I gave don't involve a display manager at all, just startx.
