Hmm? the ID_AUTO_SEAT stuff is just sugar on top, to make sure that the multiseat hw just works, without requiring any configuration. Without it it just means you have to manually assign devices to a seat, that's all. Nouveau is a driver for PCI hardware, not for the usb displaylink. Before thinking of putting together seats, try to make the displaylink hw work at all, so that you get something on screen. How to do that is out of scope for systemd I fear though, can't help you much with that. In general: systemd just keeps a database of what hw belongs to which seat, that's all. Drivers and access to the devices are done in the kernel and X11, and systemd has nothing to do with that really.

That's awfully generic...
I'd really just be interested in vendor/product ids if the usb hub
that is built into your docking station, where the display link is
connected to.
If in doubt, please run "lsusb" once before you plug in the device,
and once after you plug it in, and let me know the difference: all the
lines that appeared in the output by plugging it in.
Thanks,
Lennart

If it can help, here is the udev rule and service shipped with the rpm:
displaylink.service

Unfortunately, I didn't care at first which nvidia driver was
installed by default in Fedora22. And of course, nouveau was the one
indeed.
So I installed nvidia driver and blacklisted nouveau.

After nvidia driver was intalled:
# loginctl attach seat1 /sys/devices/platform/evdi.0/graphics/fb1
# systemctl restart systemd-udev-trigger.service
$ loginctl list-seats
SEAT
seat0
seat1
2 seats listed. AT LEAST

Re: [systemd-devel] Multi seats setup How-to
I can't create a new seat1, no idea why.
Here is my current configuration:
-nvidia card + nvidia driver + nouveau blacklisted
- USB 3 dock station with displaylink driver + systemd service
- gdm
- systemd 219

What am I missing? Why can't I create seat1 ?
Maybe # rm /etc/udev/rules.d/72* and try again ?
attach the [MASTER] graphics:fb* to seat1 and it should work.

Re: [systemd-devel] Multi seats setup How-to
Arnaud,
You must focus on the graphics/fb* syspaths (since they are tagged as
[MASTER] in udev/logind), not the drm/card* ones. You must attach the
[MASTER] devnode to a new seat in order to create it.
BTW, systemd already ships udev rules to set property ID_AUTOSEAT for
DisplayLink USB 2.0 Docking Stations, so that you don't need to attach them
manually. Maybe these rules should be updated to include USB 3.0 Docking
Stations as well.

A new udev rule is shipped with the package.
/etc/udev/rules.d/99-displaylink.rules
-
ACTION=="add", SUBSYSTEM=="usb", ENV{ID_VENDOR}=="DisplayLink",
MODE="0660", RUN+="/bin/systemctl start displaylink.service"
ACTION=="remove", SUBSYSTEM=="usb", ENV{ID_VENDOR}=="DisplayLink",
RUN+="/bin/systemctl stop displaylink.service"
and the systemd service is active and loaded when I plug the dock station
Now following your advices, I shall write:
/etc/udev/rules.d/72-seat-1.rules
SUBSYSTEM=="drm", DEVPATH=="/devices//platform/evdi.0/drm/card1",
TAG+="seat", TAG+="master-of-seat", ENV{ID_AUTOSEAT}="1",
ENV{ID_SEAT}="seat1"
and this:
/etc/udev/rules.d/99-nvidia_seats.rules
SUBSYSTEM=="drm", KERNEL=="card[0-9]*", ATTRS{vendor}=="0x10de",
DRIVERS=="nvidia", TAG+="master-of-seat"
SUBSYSTEM=="pci", ATTRS{vendor}=="0x10de", DRIVER=="nvidia",
TAG+="seat", TAG+="master-of-seat"
Then do the xorg.conf stuff, reload and attach keyboard + mouse ?

As for the graphic card, I am lost.
OS: Fedora 22
gdm
1 nvidia card
1 USB3 plugable dockin station for the second monitor
Nvidia driver (I would like to avoid using Nouveau if possible).
Following this old blog[0], it seems I must FIRST assign the graphic
card to seat1. So I guess first is to take care of the /etc/X11 stuff.
Once I have correctly configured it, I must be able to see two cards,
right ?
Here are the steps I took to make my multi seat with Debian Sid:
1. Install the nvidia drivers and blacklist the nouveau drivers.
2. Locate with loginctl seat-status seat0 the address of the graphic
device you want to be seat1
Maybe there is no graphic device, but I have:
├─/sys/devices/pci:00/:00:05.0/:02:00.1/sound/card2
│ sound:card2 "NVidia"
so the the gpu is /sys/devices/pci:00/:00:05.0/:02:00.0
use udevadm info /sys/bus/pci/devices/:00:05.0/:02:00.0
to make sure the address is right
$ udevadm info /sys/bus/pci/devices/:00:05.0/:02:00.0
P: /devices/pci:00/:00:05.0/:02:00.0
E: DEVPATH=/devices/pci:00/:00:05.0/:02:00.0

E: PCI_SUBSYS_ID=3842:2615
E: SUBSYSTEM=pci
E: TAGS=:seat1:seat:master-of-seat:
E: USEC_INITIALIZED=4003578
3. Make an udev rule for the gpu:
$ cat /etc/udev/rules.d/72-seat-1.rules
SUBSYSTEM=="pci",
DEVPATH=="/devices/pci:00/:00:05.0/:02:00.0", TAG+="seat",
TAG+="master-of-seat", ENV{ID_AUTOSEAT}="1", ENV{ID_SEAT}="seat1"
4. create a x11 conf for the nvidia device
$ cat /etc/X11/xorg.conf.d/90-nvidia.conf
Section "Device"
Identifier "Seat0"
Driver "nvidia"
BusID "PCI:1:0:0"
Option "ProbeAllGpus" "FALSE"
MatchSeat "seat0"
EndSection
Section "Device"
Identifier "Seat1"
Driver "nvidia"
BusID "PCI:2:0:0"
Option "ProbeAllGpus" "FALSE"
MatchSeat "seat1"
EndSection
5. reboot or trigger udev to load the rule
6. Check if the seat is created
$ loginctl list-seats
SEAT
seat0
seat1
2 seats listed.
7. use loginctl attach and connect all other devices to seat1
success,
