Hi,

This is the error I am getting after completing the LiveCDCustomization 
instructions and after installing the new iso:

http://aiolos.survey.ntua.gr/owncloud/public.php?service=files&token=a361093bd36debbd157827b17b296b045fb0e991&file=/error-lightdm.jpeg

The scripts used to do the installation are located here:
https://trac.osgeo.org/osgeo/browser/livedvd/gisvm/trunk/bin/build_chroot.sh
https://trac.osgeo.org/osgeo/browser/livedvd/gisvm/trunk/bin/inchroot.sh

We are creating a "user" during chroot to be able to install stuff to 
postgres and some other desktop stuff and then we move those to /etc/skel

I also noticed that after installation the guest account can actually 
log in and works fine.

Perhaps we have an issue with the custom casper.conf we create?
https://trac.osgeo.org/osgeo/browser/livedvd/gisvm/trunk/app-conf/casper.conf
or this?
https://trac.osgeo.org/osgeo/browser/livedvd/gisvm/trunk/app-conf/README.diskdefines

Thoughts?

Regards,
Angelos
