There are cuda packages for arch. I can confirm they work.

Edit- to add i haven’t found arch’s limit, it feels like i am bound only by my own limit in my time, ability, and willingness to tinker with my setup. arch itself is widely supported, it has many official packages through pacman, and then additional through the “arch user repository” (AUR) so chances are most of the things you want or need have a package that can be installed with an AUR helper (like yay/paru which install from both pacman and AUR). In other distros you get more of a one-size fits all and you lose some of that ability to change things whereas arch you’re giving a minimal setup and left to build the system to your liking. It does take more time and expertise than other distros but it does give you more control. For me the trade off was an easy decision, but it’s not something i blanket recommend to everyone.




For iTunes based music player there is also rhythmbox which is standalone (no subsonic server needed). It’s what i used until i ultimately switched to navidrome + supersonic. I’ll check out feishin since that didn’t come up in my initial search last year. Ive liked supersonic though. It has a decent, simple UI and you can play albums by clicking on them
Edit: ok feishin seems pretty cool. I might stick with this
