I can’t say I’ve had those issues myself, so my recommendation may not be valid in your case. I’d say maybe give Fedora with KDE Plasma a try, and try switching between X11 and Wayland sessions if issues persist.

I personally don’t like Ubuntu, but that’s mostly because of Canonical making the occasional sketchy decision.

On the whole, distro choice doesn’t matter quite as much these days, as most distros should work fine out of the box. Whatever issues you have should technically be solvable with a bit of troubleshooting.

Sometimes Linux just doesn’t play well with your setup. Good luck, and I hope you find something that works for you!

Won? They will do it again. The only winning move is not to play their game. Choose Free Software.

Is SteamOS even available for desktop PCs yet? I don’t think it is.

From the SteamOS page:

We expect most SteamOS users to get SteamOS preinstalled on a Steam Deck or device that incorporates SteamOS. The only devices officially supported on SteamOS right now are Steam Deck and Legion Go S. We are working on broadening support, and with the recent updates to Steam and SteamOS, compatibility with other AMD powered PC handhelds has been improved.

Until this changes, which I think is in the works, I recommend using some other popular distro.
