All great! What's wrong with Arch! I like Arch!
My personal reason is
incredibly petty. Couldn't get a Java-based music Discord bot (
this one, if you're curious) to run on Manjaro ARM on my Raspberry Pi 4. Gave me some library errors after installing the JVM, couldn't figure it out. Decided that if it's gonna give me shit on this tiny thing, I'm gonna suffer
a lot later, nuked the SD card and went back to Raspbian Lite. I've only been using Linux on this one board, so my experiences there probably won't reflect my experiences if I tried Arch on an x86 box.
I'm boring, I only use Raspbian Lite on my Pi because it just works, you know? Mostly, there's the odd "enabling video decode on Chromium", "if you install Network Manager, purge
dhcpcd5 and
openresolv, or NM and the other two will fight to the death" and "dual-monitor is annoying with some capture cards, force-set the HDMI mode for both displays in
/boot/config.txt to prevent
tty modes from running in the lower of the two resolutions". You know. Just works. Mhm. Just works. Totally. KDE works okay on a Pi 4, but I overclocked to 2.3 GHz on mine. Protip: disable the compositor.
That's for a Pi. I don't yet own an x86 Linux box, but my brother dropped off his old gaming rig (Ryzen 1000/2000 (guessed based on motherboard and general age), GTX 960, 8 GB RAM). He says it's fine, just that the PSU is dangerous, and whatever storage devices were in there were cannibalized. I've already ordered an SSD and PSU for it, so if it works, I'll have a free box to tinker on that isn't a Raspberry Pi for once! Love those things to bits, but you ever try running the KDE compositor on those, even overclocked? Not happening.
If I wanted to be normal, I'd run Ubuntu on it (specifically Kubuntu, 'cause KDE). If I wanted to go insane, I'd go straight to NixOS or any of the other "weird idea" *nixes.
