VR is only usable if the game and the entire supporting stack works perfectly (graphics drivers, USB 3 controller, power management etc). There are tight framerate/latency requirements and everything goes through intricate off-screen rendering as VR headsets don't pretend to be an additional monitor anymore. This leads to two classes of major problems: total failure (crashing outright) and stuttering (low framerate, high latency, or occasional "hiccups"). These are equally unacceptable (stuttering ruins VR and can make you feel ill). It is difficult enough to avoid these issues on Windows where the OS vendor, the graphics card vendor, the motherboard vendor, the game developer, and the VR rendering API developer are focusing their attention and releasing frequent patches to fix VR issues. There seems to be a general opinion that an Nvidia GPU on Windows 10 is the standard VR development target. If VR doesn't work perfectly for you on Linux, it's going to be a pain to sort it out, assuming that's even possible without hoping a third party releases an updated binary blob in the future. Valve does pay attention to Linux and provide SteamVR support, but they haven't officially released Half-Life: Alyx for Linux yet. They will probably release more information about compatibility when they do.
