I used Manjaro for two years, but it broke in some terrible ways during that time. I’m on Tumbleweed now and it’s OK. Getting NVIDIA working was a mess.
I’m building a new machine and will be trying the immutable Universal Blue on that one. It should be crazy stable, based on Fedora. They have images with NVIDIA drivers built in. The core system is untouchable and this would be the perfect distro for someone who wants a stable system that will just work “forever” and does not want to tinker. You’d be using Flatpaks for darktable and other GUI apps, Distrobox for CLI apps.
However, this thing is not traditional in any sense and I recommend starting with this video and then checking out Jorge Castro’s YT channel if you’re interested.
