Note: I haven't documented CUDA here. I'm lazy (and haven't tested on Arch). See https://documentation.ubuntu.com/wsl/en/latest/howto/gpu-cuda for that on Ubuntu.
So I got this working on both Ubuntu, and Arch. First, start with a fresh install (of archlinux from https://gitlab.archlinux.org/archlinux/archlinux-wsl or Ubuntu from
wsl --install Ubuntuor https://apps.microsoft.com/detail/9pdxgncfsczv).
- Install
mesaandvulkan-dzn. - Run
echo "L+ /tmp/.X11-unix - - - - /mnt/wslg/.X11-unix" | sudo tee /etc/tmpfiles.d/wslg.conf. (Thanks to microsoft/wslg#43 (comment) for this.) - Create your user account as per https://wiki.archlinux.org/title/Users_and_groups#User_management and confgure it as the default user for WSL as per https://wiki.archlinux.org/title/Install_Arch_Linux_on_WSL#Set_default_user.
suinto the user or open a new terminal tab/window.- Run:
cat << EOF
export GALLIUM_DRIVER=d3d12
for i in "/mnt/wslg/runtime-dir/"*; do
[ "$XDG_RUNTIME_DIR" = "$HOME" ] && XDG_RUNTIME_DIR="/var/run/user/$UID"
if [ ! -L "$XDG_RUNTIME_DIR$(basename "$i")" ]; then
[ -d "$XDG_RUNTIME_DIR$(basename "$i")" ] && rm -r "$XDG_RUNTIME_DIR$(basename "$i")"
ln -s "$i" "$XDG_RUNTIME_DIR$(basename "$i")"
fi
done
EOF | sudo tee /etc/profile.d/wslg.sh`
- Restart WSL with
wsl --shutdownfrom CMD/PowerShell and you should see the following (given you install the relevant packages):
$ glxinfo | grep Device
Device: D3D12 (NVIDIA GeForce RTX 4080 SUPER) (0xffffffff)
$ vulkaninfo | grep "GPU id"

- Go to https://ppa.launchpadcontent.net/kisak/kisak-mesa/ubuntu/pool/main/m/mesa/.
- Look for

sudo apt install <PACKAGE>(in your case,sudo apt install mesa-vulkan-drivers_25.0.1~kisak1~n_amd64.deb. - Run:

The reason we're using just the Vulkan driver from Kisak's repo. is that the mesa package causes llvmpipe to be used instead of D3D12. Maybe overring GALLIUM_DRIVER would work - I didn't try.
