J'essaie de lancer ovrd qui devrait «This lights up the LEDs on the DK2 HMD, opens the video stream from the camera and provides the position of the headset to VR applications.»

L'Oculus Rift DK2 (Development Kit 2) date de 2014 : https://en.wikipedia.org/wiki/Oculus_Rift
petit historique : https://en.wikipedia.org/wiki/List_of_virtual_reality_headsets
Il y a 5 ans : (source : https://www.reddit.com/r/OSVR/comments/diic4v/comment/f45s3ei/) «The latest official from Oculus and working positional tracking driver for the DK2 [was the 0.5.0.1 SDK](https://developer.oculus.com/downloads/package/oculus-sdk-for-linux/). The source code for most of this SDK is available in the download, except for the implementation of the positional tracking. The way you use(d) the DK2 on linux was by downloading the SDK, extracting it, and running ovr_sdk_linux_0.5.0.1/Service/OVRServer/Bin/Linux/x86_64/ReleaseStatic/ovrd. This lights up the LEDs on the DK2 HMD, opens the video stream from the camera and provides the position of the headset to VR applications.
OSVR-Oculus-Rift is a plugin for OSVR-Core, which connects to this ovrd service and makes the DK2 poses available in OSVR.
And lastly, SteamVR-OSVR is a plugin for SteamVR, which connects to OSVR and makes the DK2 poses available in SteamVR.
So this is the only software stack where you currently get the original DK2 positional tracking in SteamVR on Linux. So for it to work, you need to first start `ovrd`, then `osvr-server` with the dk2 config from the dk2 plugin, and then SteamVR with the SteamVR-OSVR plugin installed.
Back in the day I did try this setup and it did work, but it is a hassle to run OSVR as a middleman.
Once there's a new implementation for the positional tracking from OpenHMD, there will be software stack that's easier and quicker to set up.»
