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.
