So you want something like a "hybrid" session, i.e. one that is virtual
but has access to local devices? That's a special setup that is not
supported by logind itself. However note that you can express any
policies you like with polkit, hence you can configure it to grant
access to the devices to your user even if he is not logged into a
physical session. But that's something you have to do unrelated to
logind.
