VR

SteamVR

SteamVR is not currently functional under FEX.

TO-DO: Describe the result from running SteamVR

Monado

Generally the preferred VR runtime of choice on Linux. An open source OpenXR runtime with support for a plethora of headsets.

Building

Aarch64 Monado will not be able to run x86-64 VR applications, so for the majority of VR software, you will need to build Monado for x86-64

Envision

Envision is a GTK4 frontend that simplifies the ease of use for Monado.

• This can be built for x86-64 in the RootFS if need be, however they also provide Appimages on their Gitlab
  • If you have issues running the appimage directly, you run the appimage with the `--appimage-extract`, then run the binary in `squashfs_root/usr/bin`

Problems

SteamVR headsets have unstable tracking

Headsets like the Valve Index which rely on SteamVR's lighthouse drivers for tracking will experience periodic freezes of the VR view

• No idea why this happens, but it makes the Index practically unusable in this configuration
  • Libsurvive lighthouse driver might provide different results, but this has yet to be tested.
