I was missing one piece of the puzzle. My USB dock station is Plugable® UD-3900 USB 3.0-------------------------------------------------------- 1- I had to install the kernel driver for it, following instructions per this displaylink forum[0]. Once the .rpm package installed, I could verify: $ lsmod | grep evdi evdi 36864 0 drm_kms_helper 122880 2 evdi,nouveau drm 331776 10 ttm,evdi,drm_kms_helper,nouveau # ll /lib/modules/$(uname -r)/extra/evdi.ko -rw-r--r--. 1 root root 63072 3 sept. 14:29 /lib/modules/4.1.6-200.fc22.x86_64/extra/evdi.ko ------------------------------------------------ 2- Now $ loginctl seat-status seat0 returns something more interesting: ├─/sys/devices/platform/evdi.0/drm/card1 │ drm:card1 So I guess now I have indeed two cards.
Lets make things clear. The usb dock will be your second seat. I think the next steps will be enough: loginctl attach seat1 /sys/devices/platform/evdi.0/drm/card1 loginctl attach seat1 /the path to the usb3 hub everything you didn't attach with loginctl or with an udev rule will be part of seat0. So if your nvidia card is for seat0 you don't have to write a rule for it. success, floris _______________________________________________ systemd-devel mailing list systemd-devel@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/systemd-devel
