Solution

Multi-seat support for LightDM was discussed during development and a fix has been released for Oneiric:

Support multi-seat setup. This is (I think) when you run two sessions on a single X server (with two displays/keyboards/mice).

The basic configuration of lightdm.conf is

[LightDM]
displays=display0 display1

[display0]
xserver=xserver0

[display1]
xserver=xserver1

[xserver0]
layout=layout0

[xserver1]
layout=layout1

The lead developer also gives this example in the report:

[LightDM]
xserver=default-xserver

[default-xserver]
command=/usr/bin/X -foo
config-file=/etc/X-foo.conf
layout=layout0

Thus for each video card you need to define an X-session (through xnest & xephir)

In the report a specific example of a xorg.conf file should support for multiple nvidia displays.

In terms with running multiple X sessions from one video card this is currently unsupported.

I hope this answer gives you some ideas to work through.

The only reference I know of is here : help.ubuntu.com/community/MultiseatX I have no experience with this uncommon setup.

Thanks, I already read that, but as far as I know that instructions are for GDM, not LightDM and the GDM you have to use is an older version, I don't want it.

Sorry that information was not helpful.

@RodrigoMartins - what lightdm.conf options have you tried from this bug report? bugs.launchpad.net/lightdm/+bug/593493

@fossfreedom - This is just what I'm trying to do, but I cannot really test my LightDM configurations until I have my xorg configured, I know how to basically modify the xorg configurations, but I don't know how to say to it start a layout using the screen attached to the VGA output. I'll update my question about it. Make your comment an answer and I will award the bounty to you.
