OpenHMD VS SteamVR-OpenHMD

I modified the AUR package for openhmd to build your repo/branch instead. git+https://github.com/thaytan/OpenHMD.git#branch=rift-kalman-filter But the tracking is just as jittery as before and it's still just 3DOF. Is there any special compiler flags or something that need to be activated for 6DOF to work, or is it more likely that I just installed it wrong somehow?

Yes. Was developed by the same guy, in fact: https://github.com/thaytan/OpenHMD/tree/rift-kalman-filter

if they wanna stay with Oculus, they could give the CV1 a try, assuming they know how to setup the drivers for it to work on Linux. Thaytan on github has been working on and improving 6DOF tracking for the CV1 for a while now but is needing help with the tracking part of it to fix a few kinks. You can easily okay Beat Saber with it no problem. Should give it a look if you are interested. Thaytan has some youtube videos as well of some gameplay with it. The branch on github you would want to use is the rift-correspondence-search one. https://github.com/thaytan/OpenHMD/tree/rift-correspondence-search

Oculus Rift DK2/CV1: Try my positional tracking branches of OpenHMD (https://github.com/thaytan/OpenHMD/tree/rift-kalman-filter and https://noraisin.net/diary/?page_id=1048)

I re-measured distortion parameters on my CV1 last month (https://github.com/thaytan/OpenHMD/commit/46d164a9) and they made things much clearer for me... maybe those parameters aren't right for your headset? Unfortunately it's a really hard thing to get a photo of for me to tell what you're seeing on your end.

https://github.com/ChristophHaag/SteamVR-OpenHMD with https://github.com/thaytan/OpenHMD/tree/rift-kalman-filter would work for now getting the CV1 working positionally tracked on Linux (currently in branch, still experimental but usable!) There are step by step install instructions on https://noraisin.net/diary/?p=1033

Your best bet would be somehow run this on windows https://github.com/ChristophHaag/SteamVR-OpenHMD

There is an ongoing discussion about getting Rift S + SteamVR-OpenHMD working in Windows here: https://github.com/ChristophHaag/SteamVR-OpenHMD/issues/68

So i tried to see if SteamVR plugin do the paring stuff with SteamVR(version BETA: "linux_v1.14 - Older build, for linux users", newer version of SteamVR don't worked for me)

SteamVR is supported through the SteamVR-OpenHMD project (https://github.com/ChristophHaag/SteamVR-OpenHMD)
