Platform:

  • OS: Ubuntu 21.10
  • HMD: HTC Vive

Fork:
Soon I guess

Additional context
Hey,
I really want to port this to Linux.
At the moment this is the main think stopping me from using VR in linux daily.

Can you provide build instructions so I can try and get it to work here?
Thanks!

So I started setting up an environment to get this project to work on Linux.
I am documenting here how well this is going for other people, since unity are not that great on that.

Will note that 2019.3.1f1 listed here does not exist for linux. So I am trying 2021.2.6f1 just to see if I get something running.

I had to hunt down a non-beta version for Linux of unity since that is buggy as hell and wont let me

  1. Activate the license
  2. Download an editor

The appimage for stable unity on Linux is at:
https://public-cdn.cloud.unity3d.com/hub/prod/UnityHub.AppImage

Editor install binary you need to run (currently) at:
https://download.unity3d.com/download_unity/8c4e826ba445/UnitySetup-2021.2.6f1

  1. Once you install that unity version and click on it actually lets you install 2019.3.1f1

Ok, so I gave up on building it on Linux, because Unity does not run that well on linux. And neither does this version.
I booted to windows and built LuxVR there.
When I run it locally I get these errors:

Another thing I tried - copy libopenvr_api.so to LuxVR_Data/Mono (had to create the folder).

I manage to see in SteamVR the button to open LuxVR, but the window seems to be empty:

Would appreciate help how to continue from here. I am not much of a unity developer as you can see. But this might actually work.

Hey, Just ran grep in your code and saw you are using hmdDisplayColorGainB values which don't work for me on linux. I am unsure how to get this working without them.

Hey @guysoft, I appreciate your interest in porting LuxVR to Linux!

Linux & Unity:
Sadly, I don't have any experience with building Unity applications for Linux systems. Perhaps the best bet (for Linux) is to fork OVRAS and extend/modify their existing codebase which is built on Qt, C++, and OpenVR API. I don't feel proficient in Qt and C++ so that's why I worked on Unity and C#.

hmdDisplayColorGain and Overlay App Window:
It's interesting how adjusting hmdDisplayColorGain values did not work for you. When you are using OVRAS and adjusting the Color values there (Video Settings > Color Adjustment), did it also not work for you? If not, it indicates that your headset is incompatible with some features of the OpenVR API, at least in my experience. But it should work on your HTC Vive, and it does too, having opened the LuxVR window as an overlay application after copying the libopenvr_api.so.

Just to briefly explain how the rest of the process works;
The Unity application renders a camera and draws the rendered images on the OpenVR overlay application window at each frame (while the application is being displayed). In your case, it does not display anything (for some reason).

LuxVR is based on benotter/OVRLay, you can see where the above operation is performed here and here. A bit of debugging might reveal the issue here.

Let me know how it goes.

Hey @egemenertugrul, thanks for the reply, here are the answers, I fiddled a little more since reporting this:

  1. Linux & Unity: I have managed to build it on windows now. You can just set the target to Linux and you get a binary. I can test stuff if you need it. That is how I got the screenshot result here.
  2. hmdDisplayColorGain and Overlay App Window: brightness (I think hmdDisplayColorGain) does work, the RGB values don't work. I tested and on the same machine on windows they do work. I also posted this issue there: Cant see all of settings in video - can't scroll neither OpenVR-Advanced-Settings/OpenVR-AdvancedSettings#579
  3. LuxVR is based on benotter/OVRLay: Would love to test and report, if you have anything you would like me to try.
    I did manage to build the overlay in the openvr sdk. Got a screenshot of there here: Fix -G "Unix Makefiles" for linux cmake commnad ValveSoftware/openvr#1618 (comment)

Sorry for the very late reply - I thought I have already gotten back to you.

I wish I knew why adjusting the RGB values doesn't work on the Linux build.

Do the sliders also act buggy on Linux? If so, would you happen to have an idea as to why the sliders don't work as intended?

I think its setting it, changing the RGB values manually does not effect the screen. see ValveSoftware/SteamVR-for-Linux#462
I don't think its a UI issue, its a bug in SteamVR-for-Linux
