edubuntu and xubuntu use /etc/gdm/gdm-cdd.conf to override default gdm settings (mostly the greeter theme). See /etc/init.d/gdm.
On the livecd the installed gdm config file is further modified to default to autologin. In a qemu xubuntu live session I am looking at, even if /etc/gdm/gdm-cdd.conf is installed, /etc/gdm/gdm.conf was touched instead by casper-bottom/autologin.
So the xubuntu theme is there but autologin is not.
related but not quite the same thing
