This is still a bug in Jaunty. The cause is apparently that the /usr/share/edubuntu-artwork/gdm/gdm-cdd.conf file is now out of sync with the /etc/gdm/gdm.conf file in some of its defaults, and gdmsetup appears to largely ignore the former. The fix, in such a case, would be to update that file to match miscellaneous settings in the /etc/gdm/gdm.conf file.
