ROG Xbox Ally X controller Doesn't Work on Bazzite

I just got the new ROG Ally X and decided to test out Bazzite using the Deck ISO (the one for ROG Ally / Ally X). The system boots fine and everything seems to work. Except the built-in controller isn’t being recognized.

I’m happy to help debug or provide logs if needed since I’d love to contribute and help get full Ally X support working for this awesome OS.
