As we know in issue #308 that mesa uses llvmpipe instead of D3D12, if my laptop has a nvidia gpu as well, how to make Arch use Nvidia GPU like the Ubuntu WSL do?

[RayneScofield]

For my Ubuntu WSL that GPU indicates NVIDIA GeForce GTX1060

❯ glxinfo -B

OpenGL ES profile version string: OpenGL ES 3.1 Mesa 23.2.1-1ubuntu3.1~22.04.2

Is it possible to config Archlinux to perform this way?

does your arch have /usr/lib/dri/d3d12_dri.so?

[RayneScofield]

does your arch have /usr/lib/dri/d3d12_dri.so?

no, there is no /usr/lib/dri direcoty.

no, there is no /usr/lib/dri direcoty.

/usr/lib/dri/d3d12_dri.so is owned by mesa 1:24.0.7-3
reinstall mesa
maybe your installation is corrupted

I have the file, but it still uses LLVM as renderer.

try MESA_LOADER_DRIVER_OVERRIDE=d3d12 glxinfo -B | grep render
what do you see?

The same as before.

Is your gpu included in this (including same driver version or more recent)?

yes, I use a laptop with two gpu. A GeForce RTX 4060 laptop with driver 551.86 and a Intel Iris Xe with driver 31.0.101.4502.

AFAIK it should work out of box if you have guiApplications=true in ur .wslconfig
maybe someone will find out what i missed here

Hi I had the same problem this thread is about and I think I've figure out a fix for this from microsoft/wslg#1254 (comment) and microsoft/wslg#1254 (comment)

[xuangeyouneihan]

Hello, I have the same issue here. When I rebuild Mesa according to @AreamanM's method, it tells me that fakeinstall/usr/lib/libspirv_to_dxil.a is not a directory. What should I do now?

thats because libspirv_to_dxil.a is a static library
anyways i use this script

  _install fakeinstall/usr/share/vulkan/icd.d/dzn_icd*.json
  _install fakeinstall/$_libdir/libvulkan_dzn.so
  _install fakeinstall/$_libdir/libspirv_to_dxil.so
  _install fakeinstall/$_libdir/libspirv_to_dxil.a
  _install fakeinstall/$_libdir/clon12compiler.so
  _install fakeinstall/usr/bin/spirv2dxil

[xuangeyouneihan]

In package_microsoft-dozen-driver()?

[dmitry3l]

In package_microsoft-dozen-driver()?

obv yes

[jaxvanyang]

mesa package maintainer has updated the PKGBUILD, the _install function is replaced by the new _pick function. So the workaround script need update too. And I created a fork here: https://gitlab.archlinux.org/jaxvanyang/mesa/-/blob/dozen/PKGBUILD. It should be enough to use.
