Has anyone done a multi seat setup?
I am trying to do it with lightdm which is supposed to have built in
ability for multiseat.
I am able to get two mouse pointers but not independent.
I get two keyboards but working as one.
Both screens are controlled by one user with one single login instead
of getting two independent lightdm login greeters.

I have tested the same, with a few caveats. My test setup was based on
Fedora 26, with consolekit used to manage seats and the input device
pairings. The Caveat was that each seat had to have an independent display
card/device. Multiple outputs connected to a single card cannot be used to
do a multi seat configuration(At least not yet. but is being worked upon by
me).
I am trying to do it with lightdm which is supposed to
have built in
ability for multiseat.
I tested it back then with both LightDM and GDM, both of which had built in
multiseat support in F26. I intend to be running some more experiments on
the same once I'm back in mumbai in a couple of weeks. Will report more
details then.

There are 3 - HDMI, D-sub (VGA) and DVI-D
I am trying to use HDMI and VGA.
So far havent been able to start 2 independent tty or x session, one
each on each display. It is always one login. Copy whne it is a tty
and xinerama when X. Option Xinerama 0 has no effect.
lightdm starts 2 X sessions one for seat0 and one for seat-1 but gets
no response from the one being started on VGA, and shuts that down.

There are you using the On-Board Display ports as seat 0, and the addon GPU
ports as seat1? Or do you have multiple on-board ports with a single
display controller serviing multiple seats? Could you share your 'loginctl

There are you using the On-Board Display ports as seat 0, and the addon GPU
ports as seat1? Or do you have multiple on-board ports with a single
display controller serviing multiple seats? Could you share your 'loginctl

There is your problem. You only have 1 Display Device. The DRM subdevices
arent independent devices, but rather all paired with the a single
framebuffer device. assigning the DRM devices and the framebuffer device to
separate seats does not magically make them 2 separate seats. Basically the
error above is because the DRM(Rendering) portion of the drivers arent able
to find a place to render into, A.k.A a framebuffer. The basic requirement
for this style of multiseat is a separate framebuffer per seat, which you
only get with separate graphics cards, not a single card that just happens
to have multiple outputs. In such a scenario, we would have to go with a
xnest type solution, which is the direction my experiments are moving in.

Single on board gpu (AMD Vega11) with multiple display controllers.
There are 3 - HDMI, D-sub (VGA) and DVI-D
I am trying to use HDMI and VGA.
