I don’t really like debian. I can respect it as a good distro that’s based and all, but It doesn’t fit my use case of ‘just works’ the same way my steamdeck does (in regards to gaming and Windows similarly). For that I’ve found Bazzite or Kubuntu for their usage of KDE. (also manjaro was buggy 🤷♀️)
I still can’t decide if I want to use Arch based to be similar to my SteamDeck, or Ubuntu based because dealing with packages is confusing.
However I have semi-given up on Linux for my desktop PC because Nvidia sucks and I’ll try again on my semi-anually “ooo let’s try Linux again!” after Microsoft makes another dumb change. I’m gonna stick with it one day lol
Bazzite (fedora based) is actually more like steamOS than Arch is like steamOS, as both Bazzite and steamOS are immutable. I love Bazzite/Aurora/Bluefin because they have the option to include Nvidia drivers preconfigured out of the box. There have been some improvements in KDE for NVIDIA recently, so maybe check it out. One quick question, why is dealing with packages a pro point for Ubuntu?
Try Fedora KDE spin next time. It handles my Nvidia GPU without any trouble.
That might just be your GPU. If you’ve tried different distros and had issues on others then you’re probably right but different Nvidia GPUs can have varying success. I use two machines with different Nvidia GPUs (both running endeavourOS) and one needs drivers from flatpak to play games at more than ~20fps.
