I didn’t delve deeper into customization of the system, since Gaga is just a test machine and I’m not really using her for actual work. As soon as I see a new promising Linux distro pop up somewhere I’ll install that one and will let you know about my experience.
If you not totally blind anymore and want a highly stable, maintenance free system you never need to even shut down and restart, and wanna run your govt/military critical servers out of your nuke proof dungeon: Sparky Linux. Can also replace your Mint with it!
If you a silly fashionista who wants to look cool without having much of a clue how she got there: EndeavourOS. Is easier than it looks and comes highly recommended by silly airhead Orca.
