OpenHMD VS surface-aggregator-module

What headset do you have? VR works great when it works, but the protocols on Linux don't play well with all headsets. If you have a Vive, Vive Pro, or Index, it should work well with SteamVR. Otherwise, you'll have to dig around and test yourself using something like OpenHMD or more likely Monado, which both have limited device support. In my search, I came across this page, which might help you out.

A quick search suggests that people have been struggling to get HP Reverb (and the G2) headset working in Linux, particularly with SteamVR. OpenHMD has this issue open currently, though with no recent activity. I don't own any VR headsets, so I won't be of much help.

Here A guy fixes the same issue by defining which port to use I think but running

This is called OpenHMD watch a video on it to see if you are interested https://github.com/OpenHMD/OpenHMD

Sadly it looks like they already got a dump of both the 8kX and the 5k+ a few years back with no progress from it, and the project has been in limbo since the last commit is from 2021

For WMR there's the OpenHMD project which gives only seated play, no motion tracking.

There are also Open Source driver for CV1 and a lot of other headsets with OpenHMD, those drivers however are mostly just 3DOF, which limits their usefulness.

https://github.com/OpenHMD/OpenHMD i used this to get my Oculus Rift CV1 "running". There are prebuilt packages in the AUR.

A derivative of checkn1x built on Debian Linux instead of Alpine Linux with linux-surface's surface-aggregator-module preinstalled to add keyboard support for various Microsoft Surface devices.

Ahh, that will be hard, however the linux community is great and has pretty much reverse engineered this https://github.com/linux-surface/surface-aggregator-module.

Other platforms, such as Microsoft's Surface devices have the Surface Aggregator Module whose role(s) haveexpanded to scopes such as handling input events, and over time, become much harder to handle on alternate operating systems such as Linux. Apple's T2's security processor, for example, imposes even more restrictions (and at a wider scope) than Microsoft's SSAM implementation.
