VR support for linux has been lacking and the communication around it has been pretty damn poor by Valve and HTC, but it seems this is about to change at SteamDevDays .

There will be plenty of talks across today and tomorrow, and I've seen plenty of developers chatting about it in my list of Twitter followers. Sounds like a lot of excitement around SteamDevDays.
I am really excited to see the videos of the talks afterwards, and hopefully we will get a real announcement on when Linux support for the HTC Vive will actually land.
