AFAIK, Weston-DRM automatically takes all connected outputs into use,
unless specifically told not to in weston.ini, or the kernel reports
them as disconnected.

I assume fbcon runs fine cloned to both displays, right?

You are using Weston with the DRM backend, right?

Fbdev-backend cannot deal with more than one output.
