Double vision

[Sersys]

Hello,

I've managed to get to the point where I got the display working but I have double vision. In SteamVR the pictures are atop of each other and in Monado (Envision) they are next to each other.

I'm on Debian13 but I used the Nix package manager to get the built drivers and then ran install.sh.
In ~/.steam/debian-installation/steamapps/compatdata/250820/pfx/drive_c/windows/system32/ I've created a symlink called vkd3d-shader-1.dll that points to libvkd3d-shader-1.dll in the same directory, also with vkd3d-1.dll pointing to libvkd3d-1.dll (without this SteamVR couldn't start the HMD).

Envision complains that

Lens distortion helper is failed to launch, HMD image most probaly will be distorted and unusable.
Error: lens protocol error: io error: failed to fill whole buffer

Make sure you have any recent version of proton installed.

tough SteamVR doesn't seem to have this problem, regardless it produces double vision.

Launching lens_server.exe by itself complains that it failed to load library

 INFO lens_server: hello from lens server
 INFO lens_server: dll path: "Z:\\home\\sersys\\.steam\\debian-installation\\steamapp
s\\common\\SteamVR\\drivers\\lighthouse\\bin\\linux64\\lens-server\\LibLensDistortion.dll"

ERROR lens_server: error=failed to load library
Error: failed to load library

Caused by:
    0: LoadLibraryExW failed
    1: Module not found. (os error 126)

not sure if this is what supposed to happen if it is launched manually and not by being called by SteamVR. I gave full permissions to the entire lens-server folder and its contents but it did nothing.
I don't know how to proceed from here, mainly because lens-server.exe lives outside the prefixes in the common folder (~/.steam/debian-installation/steamapps/common/SteamVR/drivers/lighthouse/bin/linux64/lens-server/).
Is lense-server.exe not being called with the right prefix environment?
Are LibLensDistortion.dll and opencv_world346.dll not included in the prefix environment when lens-server.exe starts?
Is there something wrong with the dlls?
Is it even lense-server.exe the problem at all? Is there a way to calibrate manually how the pictures align?

Tracking, audio, cameras (in kamoso) seem to be working just fine.

opencv_world346.dll

It is included in this repo, but is missing in your installation, install.sh should install it automatically to the lens-server directory

Thank you for responding.

I did a clean install of steamVR, I made sure I deleted everything in the SteamVR folder after uninstall. I ran the install.sh but I still get double vision.

Installation finished, try to start SteamVR

I've tried manually copying the dlls and the exe from the patch folder to the steamVR folder but it didn't change anything.
Deleting lens-server.exe will prevent SteamVR from launching the hmd but monado still runs and tracks but everything is upside-down, so I still have a reason to believe that even if SteamVR manages to activate the HMD, it's not calling lens-sever right.

Do you have any advice how to make sure SteamVR is calling lens-server with the right proton configuration?
Also since I'm on kernel 6.12.57+deb13-amd64 I didn't patch my kernel, thinking everything was merged by now, and support for fixed DSC BPP rate are only needed for high resolution mode. Could this be a problem? I don't want to mess around with kernels unless I really have to.

opencv_world346.dll

Just to clarify: opencv_world346.dll and LibLensDistortion.dll is in place at ~/.steam/debian-installation/steamapps/common/SteamVR/drivers/lighthouse/bin/linux64/lens-server/ , it's just that when lens-server is started it can't find them, I'm guessing because /common/ is not in a proton prefix.
