Hello,

SteamVR was not running. After starting it, the error goes away. This
report can be closed.

I have never tried the ChimeraX xr command on Linux, only on Windows. I would not expect it to work on Linux since the function that is giving the error

xr.GraphicsBindingOpenGLWin32KHR()

is specific to Windows (that is what the Win32 refers to in the name). And there are other Windows calls used to get an OpenGL context for the OpenXR rendering. Are you telling me this actually worked on Linux after starting SteamVR?

While it should be possible to add to the ChimeraX OpenXR code to support Linux I never had time to attempt that. Already the VR users on Windows which is where 99% of the PC VR market is hardly ever used, so it is hard for me to support Linux VR.

[colingauvin@…]

Hi Tom,

The short answer is I don't know.

The long answer is I need to reply to your reply about the "Xreality"
glasses, but I'm still testing out all possible avenues. One pair of
glasses I have (Xreal Air) have an OpenXR driver built into Monado,
which detects them perfectly fine, and I can use them as XR glasses.
However, that's only with Monado as the OpenXR provider. If I switch the
provider to SteamVR, it can't detect the glasses.

Since ChimeraX only seems to be able to do XR through SteamVR, not
Monado, I don't know if they will work with OpenXR. I tried just 'xr on'
and got this error. Then I realized SteamVR needed to be open, so I
tried opening SteamVR and 'xr on' then gave the message about "VR
headset not found, using SteamVR/OpenXR" etc. This is expected because
SteamVR does not detect my glasses.

Historically, the Valve Index has worked with ChimeraX VR mode on Linux,
so if I can get SteamVR to detect my glasses, I'm wondering if VR mode
will work. There is a custom driver for the glasses to let SteamVR
detect them/use them, so if I can get that working, I will let you know
how it fares in ChimeraX.

P.S. - thanks for all the work you do, especially on the 3D rendering
side. Stereo is dying tool but I can't get by without it.

Best Regards,

Colin Gauvin

Hi Colin,

The ChimeraX xr command uses OpenXR which in theory works with any OpenXR implementation. I have used it with Quest and the Oculus Windows PC app without SteamVR, and I have also used it with SteamVR, so at least those two OpenXR implementations work. But the OpenXR code requires specifying an OpenGL context and that is operating system dependent and I only added support for Windows.

So in summary I would expect the ChimeraX xr command to work with any compliant OpenXR library on Windows, but not work on Linux.

Tom

[colingauvin@…]

Thanks - that clarifies things. That's too bad since there's no XR
driver for the glasses on Windows. Seems like getting SteamVR working on
Linux is probably the only real shot.

I wrote the ChimeraX VR and OpenXR code and I have only tested it on Windows for the past 5 years. Before that I had SteamVR working on Linux and Mac but since there is almost no support for VR on those operating systems I gave that up. But since that time SteamVR officially dropped support for Mac (that never really existed) and officially supported Linux. But I have not tried whether ChimeraX VR works on Linux with SteamVR. OpenXR could also work with Linux but as I said I did not add the custom Linux code to ChimeraX OpenXR to allow that.

VR and XR hardware is so bleeding edge it barely works on the platforms that the venders are targeting, so to try it on some other platform like Linux is insane. The question is what PC support does XReality offer? Maybe the answer is "none", and that is why you are trying these desperate measures.
