Has anyone done a multi seat setup?
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).
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.
Using this as a guide https://wiki.archlinux.org/index.php/Xorg_multiseat
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.
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.
my lightdm.conf
[LightDM] start-default-seat=true #[Seat:*] [Seat:0] xserver-command=/usr/bin/X :0 xserver-layout=HDMI
[Seat:1] xserver-command=/usr/bin/X :1 xserver-layout=VGA
