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.

Trying it out on a gigabyte AB350+ Ryzen 5 2600gpu. Which has 3 outputs. With loginctl I can split the devices between 2 seats quite easily.

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 seat-status' output?

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. 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.
Could you share your 'loginctl seat-status' output?
Will post later alongwith xorg.0.log xorg.1.log.

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?
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. 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.
Could you share your 'loginctl seat-status' output?
Will post later alongwith xorg.0.log xorg.1.log.

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.
Thanks and Regards

Yup. Missing master device.
