> Nvidia drivers from x-swat and Dual monitors with Twinview enabled.
You are using the binary nvidia drivers, so this is not your bug. Yes, you will have neither card0 nor PRIMARY_DISPLAY_DEVICE, because the binary nvidia drivers don't provide the kernel drm driver interface. In your case, lightdm should *only* be starting after 'stopped udev-fallback-graphics', which in turn only happens after 'stopped udevtrigger'. You should probably file a new bug report for your system and attach /var/log/udev.log.
