I must admit I haven't finished getting it to work, but others have got it to work and it seems like a pretty well troden path. I think the biggest issue I have is that I use a link cable, not wifi, and even on Windows that has been an issue.

The reason I stopped trying though is because SteamVR/Steam Link has been getting updates targeted at linux and well, I may as well wait for that for a more matured and hassle free VR PC link.
