cdev sessions are still experimental. I also try to convert them into
an independent module "uvtd", which can also work without kmscon.
However, there are a lot other issues that came up during development
which need to get resolved first. For instance systemd-logind still
doesn't allow external VT managers other than the kernel VTs.

Therefore, there is currently no way to run multiple programs on seats
other than the default seat, sorry. I am still working on this, but it
needs more time.

You can only run either x11, weston or kmscon on other seats.
