This is debian 11 mate.
Built with debian tools, packages, and currently based on the stable branch (Bullseye). Here I try not to use software from outside of the debian repositories.
For all intents and purposes, this is just debian paired with the mate desktop environment with a lot of hardware support taken care of.
