I’m curious about which distros are working well with Plasma, as I had some trouble with stability in the past. I have the feeling Plasma works better with rolling release.
Plasma is the desktop-mode interface for the Steam Deck SteamOS, which is the only way I use it. I'm usually a Gnome person, as I'm one of the people Gnome just "clicks" for, despite all its issues, but I've been really enjoying using the Steam Deck as a mini computer and Plasma has been quite stable and solid for that. Did some minor customizing, and no issues at all so far!
I've been running two distros with Plasma: Bazzite OS and CachyOS. Both very different, and stellar with Plasma.
I use CachyOS in my ThinkPad and in my Framework Desktop, for work. A stellar OS, has great defaults, is very fast and prioritizes KDE although you can do other WMs too if you're adventurous.
OpenSUSE Tumbleweed and Fedora are two solid distros I've been running for a few years now.
Fedora works well with it for me, no complaints. Though I haven't yet used it through a major version update.
Yeah, Gnome consolidates feature changes into major releases every six months, so it aligns well with fixed release distros like Ubuntu and Fedora that have release cycles that are aligned with Gnome's.
KDE drops a new point release with new features ~ every four months, and has a more flexible release schedule, so it is just to just get the changes when they are released.
I'm currently running KDE on NixOS unstable which is great, but if I weren't doing that I'd still be on OpenSUSE Tumbleweed.
