Ok, I did that. No change. Edubuntu comes with two gdm.conf files:

/etc/X11/gdm/gdm.conf
/etc/X11/gdm/gdm.conf-custom

The latter is supposed to be authoritative, and it already had the line 
DisallowTCP=false but I changed that line in the plain gdm.conf file 
just in case. Then I restarted gdm and tried again. No change :-(
