One of the side effects of distrohoppititus is that there is little time to swim into the deep waters. I have mastered the art of my own setup in arch and 'buntu worlds, and have strategies for restoring my favored DEs - usually XFCE or KDE. But I have only compiled one or two programs, and didn’t really retain anything I learned.
The upside is that given, say for instance, a mid-2011 Macbook Air, I was able to quickly go through my favorite distros to find the “sweet spot” for this machine. The answer (in this instance) being KDE Neon, which I wasn’t necessarily expecting, but it worked OOTB with the touchpad and all.
This machine had been slowing down to the point of unusable for the last year or so. When I finally got my daughter a new laptop, I took this one and said goodbye to Cupertino. Now it works better than new!
Sometimes the answer is actually found in the shallow end.
