Proprietary multi seat worked out of the box for me. that is I had to add nothing to the xorg conf, just use loginctl attach commands to attach the usb devices and the video device which worked after a reboot.
Send the output of the following commands
loginctl show-seat
loginctl list-seats

Hi MariusSiuram,
I have a ubuntu 16.04 (ligntdm) pc with onboard Intel i915 and a PCI Express GeForce 7100 GS (which uses the nvidia-304). This card works with multiseat and the Nouveau driver (but with screen distortions, poor performance and monitor resolution issues) using just the loginctl attach commands.
However when I install nvidia-driver which then shows the nvidia-304 being installed, I am unable to get the Xorg to start on the seat-1 even with the changes that you have given (suitably modified).
Since it work automagically with lightdm, the nouvaeu driver (with really poor performance but functional) it appears that the mutliseat rig is fine. Something with the driver not being triggered.
Attaching the relevant commands below. please see if you can spot something I have missed.
Thanks

Hi MariusSiuram
Thanks for your post.
I have an application for a kiosk, 2 touch screens at different resolutions. The touch is obviously the mouse input.
The reason for the 2 screens in a kiosk is so that someone in a wheelchair is not disadvantaged as they can’t reach the top screen.
I have one card - multiple heads - it’s an intel card not nVidia.
Have you tried to get mulitseat working on a single card with multiple heads?
Many thanks
Mark
Maybe this helps:

if
loginctl seat-status seat0
have multiple “drm:card” and “drm:render” entries, then it is possible.
Ive used multiseat for many years with kdm and gentoo. KDM is replaced with sddm and theres no support for multiseat. I have 2 nvidia cards + intel hd , nvidias use drivers and intel seat is 2d… Now that kdm is not supported im unable to upgrade my system. It seem pretty much the same with configs kdm/gdm…
I have 3 xorg.confs xorg_left.conf middle… right… Seats are assigned in kdmrc

If I could do it with gdm (the kdmrc part) then i could breath again :)
If someone can help me migrate settings to gdm i would be thankfull. Ive attached mouses and etc though usb hubs and sound goes with hdmi / intel seat has usb sound system…
