You're also being reconfigured during the greeter, though more severely than Jane:
[+0.89s] DEBUG: unity-greeter.vala:187: Monitor is 1680x1050 pixels at 0,0
[+6.23s] DEBUG: unity-greeter.vala:187: Monitor is 1920x1080 pixels at 0,0
My guess is X defaults to mirroring, then gnome-settings-daemon reconfigures it to side by side layout. This may be visible because the greeter starts quickly as opposed to normal login where the reconfigure occurs before Unity/GNOME starts.
Thanks Rocko,
