You can use "sudo -u gdm gconftool-2 /apps/gdm/simple-greeter/disable_user_list --set --type=boolean true" because the "gdm" user controls the login screen but the above works too because it makes that setting default for all users. You can also make it mandatory with "gconftool-2 --config-source xml:readwrite:/etc/gconf/gconf.xml.mandatory /apps/gdm/simple-greeter/disable_user_list --set --type=boolean true".
