If you haven't looked into it Monando might be what you need to keep your headset running. May not work for your headset (doesn't for mine but mines not WMR and is because of my 8kx's driver)
I already did back when Microsoft announced they would drop WMR, but it was (and still is) pretty experimental, with no controller support and 6DoF requiring external tracking.
There is experimental 6dof tracking now IIRC. LVRA is a great place for VR linux info.
