I just installed AV Linux this month. So far, I like it a lot. I was using Ubuntu Studio, but got fed up with the snap packages.
AV is built on MX which is built on Debian. The desktop environment is XFCE4, so it looks a lot like Ubuntu Studio.
Also, it's an init.d system by default, although there is an alternate systemd boot provided.
Haven't tried my colorimeter yet.
@TerryHancock Thank you for the feedback. First time I hear about AV Linux, but for this article I tested MX Linux KDE (and it was super high on my list). https://www.bandshed.net/2024/01/14/av-linux-23-1-enlightened-released/ , very cool. 👍
