I'm at a loss figuring out why I can't succeed in attaching a card per seat.
This was simpler with free driver, just had to
loginctl attach seat1
/sys/devices/pci0000:00/0000:00:01.0/0000:01:00.0/drm/card0/
but it seems with those proprietary drivers cards don't show up the same way.
still no seat1 shows up after I trigger udev rules :
before any rule my cards are :
