Thanks,

The relevant logs from lightdm are:
[+0.78s] DEBUG: Logging to /var/log/lightdm/x-0.log
[+0.79s] DEBUG: Launching process 1221: /usr/bin/X :0 -auth /var/run/lightdm/root/:0 -nolisten tcp vt7 -novtswitch -background none
[+2.17s] DEBUG: Process 1221 exited with return value 1

Which shows that the X server failed to start.

From Xorg.0.log-0 there is a failure (not sure if this is the correct log, /var/log/lightdm/x-0.log would tell you for sure):
[ 16.934] (II) NOUVEAU(0): NVEnterVT is called.
[ 16.961] (EE) NOUVEAU(0): failed to set mode: Invalid argument
Fatal server error:

So it appears nouveaux has a problem starting on boot. I'll reassign this to the xorg team who can better diagnose this.
