I would like to setup a multi-seat configuration using Ubuntu Xenial 16.04.

After some researches, it seems the way to do now is by systemd through "loginctl" calls. (saw here for example).

Before diving too much into into the tutorials because i don't have required materials for now (have only one keyboard at hands), i would like to know if it is possible to achieve a "two seats" setup using only one graphic card having two outputs, HDMI and DVI. It seems two cards are required but i would like to be sure.

  • It seems to be possible with "Xephyr", but according to ArchLinux Wiki on the subject it has some limitations. I have not tried myself. I have done my setup using a second graphic card. Could be great to have some feedbacks here if you try though! Mar 19 '17 at 9:42

    @sgt-hartman Have you tried specifically using one of the outputs of the card as the device to attach in loginctl attach-device. e.g. /sys/devices/pci0000:00/0000:00:02.0/drm/card0/card0-DP-1? Feb 14 '18 at 22:39
  • @RianHunter I'm pretty sure i tried. I think loginctl filters out the output part. But this needs to be confirmed. I now use a two cards multiseat. Feb 16 '18 at 10:41

    @RianHunter : I can confirm that attaching a card's output only actually results in attaching the entire graphics card.

I also wanted to do the same thing, I found this: https://help.ubuntu.com/community/MultiseatOneCard

    This guide is nearly 10 years old. It is not applicable with systemd, which is explicitly asked for in the OP. Feb 27 '19 at 11:15
