[SOLVED] mesa can't identify intel GPU on WSL2

Hi,
    I'm using ArchLinux under WSL2. But it seems that OpenGL only use llvmpipe for rendering, instead of DX12. I followed the operation stated in https://wiki.archlinux.org/title/Intel_ … stallation but everything seems ok except that /etc/modprobe.d is empty. I've also tried to use Ubuntu under WSL2 and the renderer is proper. So I guess this problem may be correlated to arch. I list my basic information below for diagnosis.
    $ cat /proc/cmdline
    $ initrd=\initrd.img panic=-1 nr_cpus=8 swiotlb=force pty.legacy_count=0
     
    $ lspic
    $ a6e5:00:00.0 3D controller: Microsoft Corporation Device 008e

    $ glxinfo | grep OpenGL
    $ OpenGL vendor string: Mesa/X.org
OpenGL renderer string: llvmpipe (LLVM 12.0.1, 256 bits)
OpenGL core profile version string: 4.5 (Core Profile) Mesa 21.2.3
OpenGL core profile shading language version string: 4.50
OpenGL core profile context flags: (none)
OpenGL core profile profile mask: core profile
OpenGL core profile extensions:
OpenGL version string: 3.1 Mesa 21.2.3
OpenGL shading language version string: 1.40
OpenGL context flags: (none)
OpenGL extensions:
OpenGL ES profile version string: OpenGL ES 3.2 Mesa 21.2.3
OpenGL ES profile shading language version string: OpenGL ES GLSL ES 3.20
OpenGL ES profile extensions:

You will probably need to rebuild mesa with the d3d12 gallium driver. Note that whatever WSL setup of Arch  you're using isn't "normal" Arch and provided by a third party and you might get better tailored help by asking wherever you got your WSL image.

Re-install mesa with d3d12 option solves the problem. Thanks!

great, please mark as [SOLVED] by editing the title in your first post (... and while you're there maybe adjust it to more accurately reflect that you are trying this from WSL)
