Okay, so I’ve been puzzling my way through the “new” multiseat configuration method of using systemd-logind’s “loginctl” and the Display Manager instead of a convoluted xorg.conf. I have a display that reports a corrupted EDID, and as such I must work around it’s EDID by adding many things to my xorg.conf.
My configuration is as follows:
Seat0:
All devices by default, except those for Seat1
Triple monitor setup with 2x Dell U2410h landscape, and 1x Yamakasi Catleap Q270 (corrupt EDID) landscape
Seat1:
One standard HDTV over HDMI
A Logitech DiNovo mini via bluetooth
So, I pounded out what I’m fairly certain I need (more or less - in this case probably more) in xorg.conf, and proceeded to pass out devices via loginctl attach
One device in particular I knew loginctl attach would not be reliable for (the DiNovo) so I wrote a custom udev rule for it:
KERNEL=="hidraw*", SUBSYSTEM=="hidraw", ATTRS{address}=="<DiNovoMacAddressHere>", TAG+=seat, ENV{ID_SEAT}="seat1"
In the end, I’m left with a non-working second seat.
The second Xorg launches, and the seat is defined according to loginctl list-seats, but the second xorg dies early:
[ 9.282] (EE) Device(s) detected, but none match those in the config file.

Forgive the large amount of commented lines in my xorg.conf - I’ve been trying things for the past two nights to no avail. I’m going to start using more verbose logging with the second xorg to see if I can’t pinpoint why referencing the GTS 450 (secondary) using BusID isn’t acceptable with what’s being passed by logind. Everything on Seat0 works as expected, and Seat1 has all of the desired devices (including proper gain of the DiNovo - though I can’t test that it actually works for input yet)
Any insight would be greatly appreciated. I’m starting to run out of ideas.
Edit: tried increasing the log verbosity, no additional information was revealed, aside from the following lines:
