• install arch with sway the normal way

• install dependencies

sudo pacman -S git base-devel

git clone https://aur.archlinux.org/yay.git && cd yay && makepkg -si

• start sshd

sudo systemctl start sshd

• for nvidia:

mkdir drivers

• install https://github.com/dantmnf/WSLAttachSwitch on windows

• open command prompt as admin

WSLAttachSwitch.exe "Default Switch"

do now in WSL

sudo dhclient eth1

• copy proretary files

scp -r /usr/lib/wsl/lib arch-dxgkrnl:~/

• for nvidia:

ssh arch-dxgkrnl sudo -S mkdir -p $(echo /usr/lib/wsl/drivers/nvle.inf_amd64_*/)
scp -r /usr/lib/wsl/drivers/nvle.inf_amd64_*/*.so* arch-dxgkrnl:~/drivers

ssh arch-dxgkrnl

sudo mv lib/* /usr/lib
sudo ln -s /lib/libd3d12core.so /lib/libD3D12Core.so

• for nvidia:

sudo cp -r drivers/* /usr/lib/wsl/drivers/nvle.inf_amd64_*

• install dxg dkms

cd ~
git clone https://github.com/OlfillasOdikno/dxgkrnl-dkms.git && cd dxgkrnl-dkms && makepkg -si

sudo modprobe dxgkrnl

/dev/dxg should now exist

• install mesa-d3d12

yay -S mesa-d3d12 mesa-utils xorg-xwayland

Now in hyperv:

export MESA_LOADER_DRIVER_OVERRIDE=d3d12
export WLR_RENDERER_ALLOW_SOFTWARE=1
LIBGL_ALWAYS_SOFTWARE=1 sway

Now execute glxinfo in sway:

LIBGL_ALWAYS_SOFTWARE=0 glxinfo -B

It should show your graphics card

I've made an one-click installation here

I got this error

@FreddyBLtv It seems this device was not found. You can use Get-VMHostPartitionableGpu in powershell width administrator privilege to check. Look for the entry "Name". If you did found that device. You use Add-VMGpuPartitionAdapter $VM_NAME -instancePath $NAME_FOUND_IN_LAST_COMMAND to add it manually.

Yeah I got it to work but the graphics card is not showing up in the Ubuntu VM. How do you have ubuntu setup in hyper-v?

@FreddyBLtv You can check this script. It's a bit complex, but it did work.

This is what I get after running the script
