Hey, this sounds awesome! Thanks for sharing. Please consider putting all this info in the GitHub readme, it's useful for anyone who wants to pick up the project. Also please consider posting this on relevant mailing lists.

I updated my PopOS packages today. My touchpad accel changed, my two-finger scroll broke, and I am left with a bunch of debugging to do and an urge to switch to Guix full-time. I came back to this HN thread and was delighted to find your post.
