multiseat with systemd

I already know that the nvidia driver creates the framebuffer after the X server is started, so I have to create an udev rule to make a "seat-master" (or is it "master-of-seat")

on http://www.freedesktop.org/wiki/Soft...emd/multiseat/


Tag "master-of-seat": if set this device is enough for a seat to be considered existent. This tag is
usually set for the framebuffer device of graphics cards. A seat hence consists of an arbitrary
number of devices marked with the "seat" tag, but (at least) one of these devices needs to be
tagged with "master-of-seat" before the seat is actually considered to be around.

Can someone give me an example to set this tag in an udev rule?

Re: multiseat with systemd
The people of systemd where so kind to give me an example:

SUBSYSTEM=="graphics", KERNEL=="fb[0-9]*", TAG+="seat", TAG+="master-of-seat"
Unfortunately, Nvidia doesn't create a SUBSYSTEM==graphics or a KERNEL==fb0


$sudo udevadm info -a -p /sys/devices/pci0000\:00/0000\:00\:03.0/0000\:01\:00.0/

 looking at device '/devices/pci0000:00/0000:00:03.0/0000:01:00.0':

so I tried

SUBSYSTEM=="pci", KERNEL=="0000:02:00.0", TAG+="seat", TAG+="master-of-seat"
but without success,

some more tips?
