Ever heard of open access?

Sidewise? Stability through front and back

I’m fine with Arch based distros

Thanks! I will give Cachy a try, seems it has everything i need

No OLED SD support (As far as I can read based on their site)

Yes bazzite offers GNOME but I prefer something not fedora

Just only because KDE, I want GNOME

Yeah I know, but I want a OS preconfigured for handhelds

Thx, I know nobara too. No thanks fedora

Or happybrush, also german, but you need USB C charger
