I have owned the index for a few years, running it on ubuntu/mint. It is a pain. But VR is a pain generally. I go months without using the thing. Then when i do use it some bit of software has been updated and i inevitably have to spend an hour getting it to work correctly again. Honestly, VR on linux feels like using windows again.

VR is bad because nobody cares much about it. The hardware is clunky, the market tiny, and costs great. As the hardware improves it will get more attention from the FOSS community and so too will the overall experiance.
