Then you'll need to add a rule equivalent to
SUBSYSTEM=="graphics", KERNEL=="fb[0-9]*", TAG+="seat",
TAG+="master-of-seat"
but replace fb[0-9] with whatever your device is (which depends on
your hardware/driver). Ideally your distro would ship the correct
rules file with the driver...
after a couple of hours playing around your example isn't that clear.
udevadm info -a -p
/sys/devices/pci0000\:00/0000\:00\:03.0/0000\:01\:00.0/
doesn't show a "graphics" neither a "framebuffer" so I tried:
$ cat /etc/udev/rules.d/99-seat.rules
SUBSYSTEM=="pci", KERNEL=="0000:02:00.0", TAG+="seat",
TAG+="master-of-seat"
SUBSYSTEM=="pci", KERNEL=="0000:01:00.0", TAG+="seat",
TAG+="master-of-seat"
$ systemd-loginctl seat-status seat0
does show the devices, but there isn't another seat created.
