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

Off the beaten path

What is &path used for?

Vim uses :help 'path' to define the root directories from where to search non-recursively for files.

It is used for:

• gf, gF, <C-w>f, <C-w>F, <C-w>gf, <C-w>gF,
• :find, :sfind, :tabfind,

So, to get started you need to get the base OS installed using the instructions from the official docs .

$ pkg update

$ pkg install bsdtar wget proot tergent tmux openssh

Tmux is a multiplexer that lets you run multiple persistent windows and sessions on a single terminal. I had trouble getting it working in the Arch proot, so a workaround is configuring tmux from your host Termux and then creating a tmux session and starting the chroot from there. For more information on using tmux read this article, and to learn how to customize the appearance and behaviors more try this one as well as looking at the tmux-plugins Github organization for community-built add-ons.

$ termux-setup-storage

Linux Desktop on Apple Silicon in Practice

I bought M1 MacBook Air. It is the fastest computer I have, and I have been a GNOME/GNU/Linux user for long time. It is obvious conclusion that I need practical Linux desktop environment on Apple Silicon.

Fortunately, Linux already works on Apple Silicon/M1. But how practical is it?

• Two native ports exist.
