I'm using latest Windows 10 insider Dev build, with the newly introduced WSLg which offers GUI for Linux applications installed on WSL2. I'm looking for a way to verify the availability of vGPU in the host and guest OSes.

all I've found is that the GPU driver installed on host must support WDDM 3.

  • Doesn't dxdiag show the WDDM version of the driver? On the guest glxinfo or so can probably tell the mesa driver you are using.

  • @TomYan dxdiag shows WDDM 3 version for my Intel driver on host OS. the thing is, since i'm using insider build, I have a newer version of Intel GPU driver installed from Windows update, but that article is pointing to an older version of Intel GPU driver. so I don't know whether I should uninstall it and replace with older one or not. that's why I'm looking for a way to verify vGPU availability. I'm using Debian, entering glxinfo in the command line says command not found.

  • There's the package mesa-utils (and mesa-utils-extra that consists of a eglinfo).

  • Most likely you'll need a kernel and mesa package that has the support built installed as well. I doubt that they exist in an official debian repo at the moment though.

  • is it possible to verify this capability on host?
