Sadly, I'm just a secondary source as someone who uses Linux full-time (and thus can't use Virtual Desktop). I'll ask my friend who did this and get back to you if he has any information.
Edit: Wait... Immersed is available for Linux. For someone who doesn't know what all the requirements are for a VR desktop environment, can anyone list them? Assume I'm thinking about buying the Oculus 2 and want to use it with Linux + Immersed.
