ok, so you are starting to completely separate instances of Weston. Do
you expect these two instances to share something, or did you mention
the fbdev case only to show that ivi-shell does work in general, but
not with RDP-backend?

Screen replication does not work by manually starting two weston
instances as they will be independent. You'd have to use the
screen-share plugin to do that.

I think ivi-shell does not handle hotplugging of anything, so that
might be the reason why you don't see anything on RDP-backend.
Hopefully people more knowledgeable in the ivi-shell (hotplug
handling?) and RDP-backend (which things are hotplugged?) could clarify
a bit.

Btw. you are also using the ivi-controller.so that is not part of
Weston upstream, so maybe it does not take it well to have multiple
instances of it running? You'd have to ask the people who work on
