You'll need to use LDM version 2.2.15+, but you'll also need to have LDM_DIRECTX disabled (e.g. =false or unset). LDM_DIRECTX uses the port to connect to the X server remotely to display. A workaround for older versions of LDM would be to set X_ARGS in lts.conf: X_ARGS=-nolisten tcp I had originally proposed naming LDM_DIRECTX something like LDM_INSECURE. :) live well, vagrant
