You've probably worried with getting Oculus Rift to work with Xorg&Linux. I think that's total and utter waste of time. In about 5 years you have huge userbase and the main use for a desktop is to directly hook it to Rift.
Instead skip the Linux desktop and start from the Linux terminal. Most enthusiasts will have Rift-dedicated computers next year anyway! This should help you to set it up in high enough quality. I don't care if my dedicated Rift computer is unable to run as a desktop computer. I won't be using it for such purpose.
If there's a display connected that is not a rift, It's OK if it displays a blank kernel terminal or even just a black screen when rift is not using it for inview.
This is important because half of your userbase is probably not wanting to use Windows 10 forever. It's buggy, it forces updates (rather than asking you to update), it's got lot of questionable features tracking you that aren't from facebook... And the list goes on. Also Linux is going to be on every IoT device anyway. Linux or Freebsd is the future.
Also, if you don't do this, Valve might do it by moving SteamVR to Steam box. I'd fire the first shot if I were you. This is from a guy who is orienting a whole programming language around your products. I wrote this because I bought the touch controllers and experienced joy with them in my hands.
There is no financial incentive to bring it out to Linux, zip, zero nada...
Right now, it could be argued that there is no financial incentive to go big on VR either. Several early VR startups have already crashed or changed strategy. Right now VR lives on the pure desire and playfulness to go out crazy with the new tech. That kind of demography has a lot more intersection with Linux than what an ordinary demography has.
Also, the opportunity cost of coming up with Linux support is lower than it has ever been before! Vulkan API provides standardization for a lot of functionality needed for coming up with a good and a cross-platform driver base. It is very different situation compared to the time when Oculus decided to give up on Linux support after 0.5.0 and DK1.
Disclaimer: I USED DK1 with Ubuntu and played out with prototypes that way!
As much as I like Linux - it is still a nich of niches even more than what VR already is. I hate to say it - but it's still super early days for VR for another 10 years sadly. I think a VR unit/support will come to Linux in the next 5 or so, but you will be playing the waiting game until that happens. Their best bet is to focus on the current main few OSs such as Windows and Android with the third being Apple if they want to reach their goal of 1mil to 1bil users. Considering most Linux and Apple uses do not have the best of the best GPUs - it does kind of put a small hit into going those routes though. Apple is actually turning things around in IOS in iphones both in hardware and software though currently and might be secretly trying to push a new VR front base off some numbers, but that is still a little while out there to know if that is true.
It'll happen - you just have to play the waiting game for a while sadly.
Croteam is supporting LinuxVR with the Vive: Serious Sam and Talos Principle both worth with SteamVR. And from what I hear they work well on Linux (I have not tried them because I don't own a Vive yet).
