Ubuntu 21.04 VM with GPU acceleration under Hyper-V...?

Modern versions of Windows support GPU paravirtualization in Hyper-V with normal consumer graphics cards. This is used e.g. for graphics acceleration in Windows Sandbox, as well as WSLg. In some cases, it may be useful to create a normal VM with GPU acceleration using this feature, but this is not officially supported. People already figured out how to do it with Windows guests though, so why not do the same with Linux? It should be easy given that WSLg is open source and reasonably well documented, right?

Well... not quite. I managed to get it to run... but not well.

How to do it?

1. Verify driver support

Improve Fonts

Newest

Make your Arch fonts beautiful easily! This is what I do when I install Arch Linux to improve the fonts.

You may consider the following settings to improve your fonts for system-wide usage without installing a patched font library packages (eg. Infinality):

Install some fonts, for example:
sudo pacman -S ttf-dejavu ttf-liberation noto-fonts

Maintenance (or lack of it)

This is a not great piece of code I've wrote few years ago (I didn't have better things to do when I was 17, apperantly), when I was fiddling around with the V8 JS Engine. It doesn't work with newer versions of V8, since the library doesn't have a stable API. Time, where I had time to fight with the depot_tools and lackluster MSVC support for fun is long gone. I've tried to redo this example once in the past, after I've got an email notification that someone got interested in stuff that I've put on the net and have forgotten about. Toolset got even more picky than I remember it being and my attention for personal programming projects drifted away somewhere else, so it's highly unlikely that I'll update it to the newer API. But I'm leaving the code there, maybe someone will make good use of it.
