When I pressed the Escape button on Login screen, LightDM zombie
process is created in the state of defunct. I used "top" application
to view the number of zombie process. The more I press the Escape
button in Login screen the more LightDM zombie process is created.
I think this bug is similar to the following Bug #962932.
Date of observe bug: 2012-04-27
Ubuntu 12.04 LTS
I change LightDM with GDM version 3.0.4 and the zombie are gone.
