However, this is global and caused problems with the displays on the other seats. e.g. with the second seat starting Xorg and looking for the Intel device as described in the xorg.conf.d file, rather than using the appropriate Frame-buffer device. I've patched the systemd/login/multi-seat-x.c to also pass over a -configdir parameter to the Xorg it launches. e.g '-configdir /etc/X11/xorg.conf.d/multi-session-x/seat-usb-pci-
