HTC Vive supports the OpenVR "standard" - and I believe the HMD from Razer (yep, they make one - yet you never hear a peep about it) is the same. The Rift doesn't have Linux support (anymore - the original DK1 did), and probably never will. There are some 3rd party reverse-engineered drivers for it, but they are limited in only allowing for the display to turn on, and view the output, plus a couple of other minor things. Tracking isn't supported, from what I recall. For what its worth, I'm not even sure whether the Vive or the Razer offering even fully supports Linux; oftentimes you see things like "support for openwidget" actually meaning "Windows and Mac version of openwidget only". The best way to get Linux HMD/VR support is the old-school, homebrew PC VR way (you know, the way Palmer did it before Occulus) - hack it yourself.
