This happens sometimes on my machine: Ubuntu 12.04 64bit Intel SSD 335 Nvidia GTS 650 with NVIDIA drivers. lightdm version 1.2.3-0ubuntu2.3
Tracked it to a race issue - if NVRM module is loaded before lightdm starts, all is OK. (see logs in Post Scriptum)
My current configuration in /etc/init/lightdm.conf:
start on ((filesystem and runlevel [!06] and started dbus and plymouth-ready) or runlevel PREVLEVEL=S)
