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
