I upgraded LightDM and I'm having some trouble replication my old config.
What I want to do is, when booting, have multiple sessions running at on different VTs on a single seat. I mean, only one monitor/keyboard but have one user logged in on VT7 and another user on VT8 using another DE and such.
This was possible on older versions of LightDM, before integrating logind's seat detection. I just used the [Seat:x] configuration in /etc/lightdm/lightdm.conf and it did exactly what I wanted.
Problem is that now LightDM uses logind to handle detecting the seats, but it seems to ignore the fact one may want to run multiple sessions with one seat only. Configuration for the first session works fine, but I can no longer tell LightDM to start other X sessions on another VT.
I can use 'dm-tool' to start another session, but I cannot make it so LightDM does that automatically on startup nor configure the new session (i.e. autologin, which greeter to use, etc).

Was support for this officially removed or is it just not implemented yet, after the logind integration?
