SteamVR/Linux status updates - Big Picture VR mode gone?

I know it's early days and that SteamVR is focusing on getting ready for the Vive - but it would be nice to know what IS supposed to work in Linux right now with the Oculus Rift DK2.



Before the update yesterday, I was able to get "Big Picture Mode" in VR - but now the button (or the drop-down menu selection) doesn't seem to do anything. HL2 VR support also disappeared somewhere along the way (I can get it to show up in the Rift in the beta, but without headtracking) - and I don't remember there being an official note about it, although the VR tag has gone from the store. TF2 still works.



I'ts great to see the many SteamVR updates, and I'm looking forward to the Vive. In the meantime, it would be nice if you could include information about what features has been removed (temporarily or permanently) as well as what has been added in your updates.



But for now: Is Big Picture Mode supposed to be working in Linux with the DK2 - or only with the Vive dev kit?
