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)
Post Scriptum: Logs clearly showing that when lightdm is started before the
NVRM module is loaded, and dies a horrible death:
