How did you install required things (openvr, vive_ros)? The master branch of this repository is a bit outdated, and there are also several updates about SteamVR installation. (you can also check latest updates in https://github.com/ValveSoftware/SteamVR-for-Linux/issues) Anyway first, you would better to confirm if you can run SteamVR successfully or not with your PC environment.

To @iory , be careful to confirm with your PC environment, because recently I was forced to update several things around the nvidia driver and the vulkan library. Once you boot the SteamVR with online, you'll encounter some error. (see https://github.com/ValveSoftware/SteamVR-for-Linux/issues/104)

@ishiguroJSK I have installed openvr: git clone https://github.com/ChristophHaag/openvr.git vive_ros: https://github.com/robosavvy/vive_ros I am using Ubuntu 16.04 and ROS: Kinetic I am able to run steamvr on my desktop. But one issue comes is that display is not done on headset rather on the desktop monitor only. Can you tell/point me what changes you did for nvidia driver and vulkan library? I think that may be the issue.

But one issue comes is that display is not done on headset rather on the desktop monitor only.

This feature is called nvidia's "direct-mode". that treats HMD devices as not just a monitor but HMD. So, with no application using HMD, the HMD will be black out. This is correct.

Can you play SteamVR home or any other games with your SteamVR? Is there no error code like 306 or 307 in your environment? If so, you can go next step.

In short, I install the latest vulkan from source, and edit a config file. I recommend you to uninstall libvulkan (if you have). You can confirm the vulkan is working or not with vulkaninfo command.

I encountered same problem recently (2018/05) , and I managed to solve it on my PC. A while ago, I could run SteamVR with no problem at Ubuntu14.04 QuadroM4000M, driver 387.12, vulkan 1.1.70, direct-mode. Since latest steam update, the error occured and I tried to catch up latest requirement. As you can see in https://github.com/moon-wreckers/vive_tracker they install latest vulkan from the site. https://vulkan.lunarg.com/sdk/home#linux and I edited /usr/share/vulkan/nvidia_icd.json as

{
    "file_format_version" : "1.0.0",
    "ICD": {
        "library_path": "libGLX_nvidia.so.0",
        "api_version" : "1.1.73"
    }
}

With this method, I could solve my problem at Ubuntu14.04 QuadroM4000M, driver 396.24, vulkan(1.1.73), direct-mode. (However with my another PC at Ubuntu14.04 QuadroK2100M, driver 396.24, vulkan 1.1.73, the direct-mode doesn't work and SteamVR doesn't work yet.)

Yes I am getting 306 error when I run a game.

[ishiguroJSK]

If so, the solution above may solve your error. But, I don't know how the latest nvidia driver version is, because we are using 14.04. After doing the procedure above, you would better confirm the vulkaninfo command indicates that your environment is working with latest vulkan.

[sanketrahul]

Thanks @ishiguroJSK That error went away with installation of latest vulkan. But still when I run Steam VR Home, it says: Failed to launch SteamVR Home.

[ishiguroJSK]

what is the error saying in detail? have you ever succeeded playing games with your pc (includes windows OS)? We also have several pc that can't run htc vive because of hardware specification

I can play games in ubuntu also in steamvr. The error for VR Home only says: Failed to launch SteamVR Home.

[ishiguroJSK]

I don't know what happen on steamvr home, but if you can play other vr games now. you have possibility to use vive_ros.

Sorry for late reply, First, you would better compile the openvr from official ver https://github.com/ValveSoftware/openvr on ~/openvr And the latest feature of vive_ros from us is here https://github.com/ishiguroJSK/vive_ros/tree/vulkan-dev-2018 (this is my branch, not master). If you succeeded both, you can run vive_ros with roslaunch vive_ros vive.launch

[sanketrahul]

@ishiguroJSK Thanks for your reply! I just have latest version of vulkan. And then I went and ran vive_ros and it worked. But still issues with headset is there. But I think for my work I need vive_ros working only.
