I'm at a loss to explain how this could be so.  Is the file below, taken
from the lightdm source, the correct one?  Because it contains no 'start on'
condition at all (nor a 'stop on'), which means the service would never be
automatically started at boot.

# lightdm - LightDM display manager
#
# The display manager service manages the X servers running on the
# system, providing login and auto-login services

description     "LightDM Display Manager"
author          "Robert Ancell <robert.ancell at gmail.com>"

emits login-session-start
emits desktop-session-start

exec /usr/bin/lightdm


For the record, the upstart job in Ubuntu has this start condition:

start on ((filesystem
           and runlevel [!06]
           and started dbus
           and (drm-device-added card0 PRIMARY_DEVICE_FOR_DISPLAY=1
                or stopped udev-fallback-graphics))
          or runlevel PREVLEVEL=S)

All of these events are now provided at boot on a Debian unstable system
with the exception of 'started dbus'.  AFAICS, lightdm can't add an upstart
job back until dbus is upstartified in Debian.
