This! Gnome is absolutely a foil to adoption. Everyone I’ve seen try to start with Ubuntu has bounced right off back to Windows. You’re already wrapping your head around a new OS, you do not need an entirely new desktop paradigm.
So happy Valve went with the setup they did.
I would install Manjaro. It runs KDE, which is super familiar, and maybe more polished than Windows. And it is Arch-based, which means you have access to AUR apps, which makes finding programs super easy. It’s like if the MS app store actually had every program on it.
Keeping the explanations simple.
Don’t start with Ubuntu/Gnome. The desktop is way too weird, and app repository is limited.
Don’t start with Mint or Cinnamon or LxDE. Linux nerds will recommend these, but they feel “old” and are not really lighter on resources than KDE.
Highly recommend Arch-based distros. AUR feels like a miracle coming from the Windows paradigm of tracking down installer EXEs and MSIs.
I think the spotlight on KDE from Steam Deck definitely helps. It’s polished as shit, and it acts like Windows by default, and that is a good thing.
Definitely this is huge. Proton and the respective Wine advancements are exactly what needed to happen. And the headlines about some games running better on Linux really gives it a good look.
