Hi Kernel list,
I'm the IT person of a school, earlier we used multiseatcomputers for
the school, i have maded with a XGL implementation and it works fine but
not so fantastic. The school wants that i build new computers but the
XGL project is too outdated so i can't use it anymore.
How can i make a multiseatcomputer with more then one user on one card
with systemd? I have asked already to the makers of systemd but they
said it's a kernel problem.
With Systemd loginctl and the nouveau drivers you have this:
─/sys/devices/pci0000:00/0000:00:03.1/0000:08:00.0/drm/card0
│ [MASTER] drm:card0
│
├─/sys/devices/pci0000:00/0000:00:03.1/0000:08:00.0/drm/card0/card0-DVI-D-1
│ │ [MASTER] drm:card0-DVI-D-1
│
├─/sys/devices/pci0000:00/0000:00:03.1/0000:08:00.0/drm/card0/card0-HDMI-A-1
│ │ [MASTER] drm:card0-HDMI-A-1
│
└─/sys/devices/pci0000:00/0000:00:03.1/0000:08:00.0/drm/card0/card0-VGA-1
│ [MASTER] drm:card0-VGA-1
├─/sys/devices/pci0000:00/0000:00:03.1/0000:08:00.0/drm/renderD128
│ drm:renderD128
├─/sys/devices/pci0000:00/0000:00:03.1/0000:08:00.0/graphics/fb0
│ graphics:fb0 "nouveaudrmfb"
So it will be:
loginctl attach seat1 /sys/devices/pci0000:00/0000:00:03.1/0000:08:00.0/drm/card0/card0-VGA-1
For the seat1 (the VGA d-sub output for seat1 and the other HDMI output
for seat0) and of course the mouse and keyboard.
When you do this, all the graphics outputs are on the second seat
(seat1) and not anymore on the first seat. So i need to move only the
VGA output to seat1 and not all the outputs.
When i install the proprietary Nvidia drivers, i have the following:
[MASTER] pci:0000:08:00.0
│ ├─/sys/devices/pci0000:00/0000:00:03.1/0000:08:00.0/drm/card0
│ │ [MASTER] drm:card0
│
└─/sys/devices/pci0000:00/0000:00:03.1/0000:08:00.0/drm/renderD128
│ drm:renderD128
─/sys/devices/platform/efi-framebuffer.0/graphics/fb0
│ graphics:fb0 "EFI VGA"
So no VGA, DVI or HDMI items.
Linux is a very good multi-user system, so it is frustrating that it
does not work. It does work under Windows without any problem, so it is
certainly possible.Can you please check this or give me a tip somewhere
so that I can continue looking for a solution? According to systemd this
is a kernel problem, can you please solve this.
Hopefully someone can help, the children and school will always thank you!
Thanks in advance,
Gert

Do you expect that GUI output is on both seats?

No, do NOT report this on the Github tracker!
That github tracker is ONLY for bugs that occur with OpenRM (the "Open GPU
Kernel Module") but not with the the proprietary driver. If you have a bug
with the the Nvidia proprietary driver, that must be reported on the Nvidia
forum instead:

I want the result that i have one seat (seat0) on the VGA/D-sub output
of the graphic card
a second seat (seat1) on the HDMI output of the graphic card
and a third seat (seat2) on the DVI output of the graphic card
In theory it should work with the following:
loginctl attach seat1
/sys/devices/pci0000:00/0000:00:03.1/0000:08:00.0/drm/card0/card0-HDMI-A-1
loginctl attach seat2
/sys/devices/pci0000:00/0000:00:03.1/0000:08:00.0/drm/card0/card0-DVI-D-1
But when i do this all the outputs will be used on seat2 (because they
do all the outputs automaticly to the latest attached seat)
