Here is the start on:
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)
I suspect drm-device-added card0 PRIMARY_DEVICE_FOR_DISPLAY=1 or stopped
udev-fallback-graphics is emitting too soon.
here is udev-fallback-graphics:
start on (startup and
(graphics-device-added PRIMARY_DEVICE_FOR_DISPLAY=1
or drm-device-added PRIMARY_DEVICE_FOR_DISPLAY=1
or stopped udevtrigger or container))
That bare 'card0' on the drm-device-added event is quite puzzling. Is it
possible that it is simply matching as 'drm-device-added' and a second,
non primary graphics chip is causing the issue? That might explain it.
The timeline for these events is pretty complex so it will likely take
some deep thought.
Nothing in the upstart man pages suggests this syntax, event, bareword,
variable, is valid or what it might mean. It seems to have been cargo
culted to KDM as well, and come from gdm in lucid originally.
Can somebody who is affected try removing 'card0' and see if that fixes
the problem?
I suspect this might be related to bug #936552 which also has to do with
lightdm seemingly starting too soon.

Title:
lightdm tries (and fails) to start too early?
Status in Upstart:
New
Status in “lightdm” package in Ubuntu:
Confirmed
Bug description:
Sometimes lightdm comes up fine. Other times it appears to fail.
x-0.log shows it tried to load 'nv' (rather than 'nvidia' which is
what actually exists). When I then log into console and 'start
lightdm', it comes up fine (on :1).
I've not had it come up ok today, so I don't know if, when it comes up
fine, it starts on :0. No idea if the lightdm.conf needs a change to
'start on'clause, or if this is just a case of a bad shipped config
file (for module 'nv').
