More than distro hopping maybe try out a zen kernel or compiling kernel yourself and changing kernel config and scheduler, or a newer version of the stock kernel?
I’m not super current on what’s in each kernel but I’d expect latest mainline to handle newer processors better than some of the older stable kernels in some of the more mainstream slower releasing distros.
Ran Asahi for several months, tried it out again recently. It’s good/fine, I just don’t love fedora.
There’s some funkiness with the more complicated install, the AI acceleration doesn’t work, no thunderbolt / docking station.
MacBooks are great hardware but I don’t think they’re the best option for Linux right now. If you’re never going to boot into macOS then I’d look for x13, new Qualcomm, isn’t there a framework arm64 option now or was that a RISC module?
I’m also assuming you’re not looking to do any gaming? Because gaming on ARM is not really a thing right now and doesn’t feel like it will be for a long while.
Really love arch and the AUR. I’ve been tempted to get nix set up for the rare cases when there’s no AUR package or the AUR package is unmaintained. I figure if there’s no package in the AUR or nixpkgs, it’s probably not worth running.
Lan-mouse looks great but keep in mind that there’s no network encryption right now. There is a GitHub ticket open and the developer seems eager to add encryption. It’s just worth understanding that all your keystrokes are going across the network unencrypted.
