Here is the lightdm log file pulled from /var/log/lightdm/lightdm.log.
At 98.76s, I logged out of my session, but didn't get a log-in screen
again (black screen on both monitors).

At this point I killed the process (28882) so that I could downgrade
lightdm again (from ctrl+alt+F1) and log back in.

Not sure if it's applicable, but the log that was generated was with
kernel version 3.2.0-19-generic running.  Also, the proprietary graphics
driver I'm running at the moment is Nvidia v340.76.  I also tested with
v340.65 but still ran into the 100% cpu usage with the newest proposed
lightdm service.

Title:
  lightdm (1.2.3-0ubuntu2.6) 100%/high cpu usage

Status in lightdm package in Ubuntu:
  New

Bug description:
  Since updating lightdm today, one core of my CPU is always maxed out
  at 100%.  I rolled back to version 1.2.3-0ubuntu2.5 and the issue
  stopped.  I tried this with 2 different kernels: 3.2.0-77-generic and
  3.2.0-79-generic and and version 1.2.3-0ubuntu2.6 of lightdm still
  caused 100% cpu usage.
