The XBOX ONE S controllers work in raw run off the mill bluetooth these days.You can blame Microsoft for that. They specifically locked the adapter down with propriety protocols which are not available anywhere else.
There are attempts to get it working by reverse engineering, but it's not there yet.
Even the XBOX bros are fed up having to keep the dongle around.
So they are slowly dropping it because even on their own customer base people are fed up with that shit.
I'm about to receive that baby
I'll see how Ubuntu sees it but the design lab does precise in multiple places that those controllers do work with raw uncrypted bluetooth.
Sooo normally Ubuntu should pick it up just fine.
