This seems to happen everytime I boot my computer... I'm running a fresh
install of 12.10 on an i7 core, primary SSD, Nvidia drivers from x-swat
and Dual monitors with Twinview enabled.

What I've tried so far with no success:

- rename to *card0
  : seemed to have no effect as there is no card0 in my udev.log
  : also no PRIMARY_DISPLAY_DEVICE in there either, it's almost as if udev is 
not finding my graphics card properly
- added "and stopped udevtrigger"
- added a sleep 2

My last attempt was to add '-d' to exec lightdm, I was hoping to get
more info on what was going on... instead it seems to work properly now.

On a side note, after much experimentation... I have a much higher
chance of a correct boot when my external monitors are not attached.
I've only seen it fail a handful of times whereas with external monitors
attached it's nearly 100%.

Logging in and manually starting lightdm service doesn't help, it just
fails immediately again.

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').
