It peaked at 4.05% in March. The last 2 months it went just below 4% as the Unknown category increased. For June the reverse happened, so 4.04% seems to be the real current share of Linux on Desktop as desktop clients were read properly/werent spoofed.
I’ve seen a lot of people move to Mint or Pop_OS or Kubuntu. They’re Debian based so updates are pretty stable.
I personally ended up with EndeavourOS using the KDE desktop environment. I have a steam deck, so this felt very similar to me. This is Arch based so sometimes updates break things, but I’ve had more success here.
Also remember that no distro is problem-free, but neither was Windows. The longer you commit, the easier it gets.
EDIT: If you’re hesitant to fully commit at first, I also recommend dual booting with Windows. Over time you’ll use it less and less until one day you feel like reclaiming the disk space.
