LightDM - Nov 2013 - Can LightDM work with an existing X server socket?

Hi all,

I'm setting up an LXC container for Ubuntu 13.10 where the X server is
started in the host on vt6. The unix socket and authority file are
then mounted in the LXC container. I can start X sessions and
applications from the container but I can't get LightDM to use this
server.

I would really like to have the container's LightDM/Ubuntu greeter to
automatically start on this display when the container is started to
allow a graphical login. I'm aware of other options (XDMCP, vnc, etc.)
but I'm trying to do it directly through the mounted unix domain
socket. I've been trying to configure X to be started and managed by
LightDM in the container but haven't been able to do that so far.

Is this possible?

Thank you,
Shahim

Hi Shahim,

You should be able to configure LightDM to use an existing X server using
the following configuration:

[SeatDefaults]
type=xremote
xserver-display-number=0

i.e. if you already have an X server running on :0
