Request support for unhandled (no greeter) sessions

[jap1968]

There is a particular approach of multiseat in which there is only one video card with multiple outputs (some authors refer to that variant as Zaphod multiseat). In this case, to obtain several seats there is just one X session running on the extended desktop with no greeter at all. Over that X session, there are several Xephyr instances which provide the various seats. Every xephyr instance is adjusted to fit the its output device and one greeter instance runs over every Xephyr session.

Previously the parameter "handled" allowed to decide if the greeter should be executed for a given session. The two Xephyr sessions were handled but no the base X session. This feature seems to be currently missing in lightdm.

Did not know this was here. Was going to ask this. I have an Nvidia video card that has 3 outputs so I was wondering if this would be possible in Ubuntu.
