I had no idea they switched distros. Or ran Wayland for that matter! Truly it's the future. But that's a good point, being able to say on the "box" that is specifically runs SteamOS certainly brings about a level of consumer and investor assurance.
As far as the nvidia drivers go. Only advice I can offer is that I've never had any sort of auto install, package based install, or any sidestepping of the default installation of the driver work for me. It's always borked. The only reliable method I've found is the old school drop into the line terminal, shutdown all GUI, and running the nvidia provided install script (which sucks, I know).
It is in fact, a US vs Europe thing. Stateside "SMS" is ubiquitous. I put quotes because it's not really SMS anymore. It's either RCS between Android users or iMessage between iPhone users. The only time SMS actually gets used is between Androids and iPhones, because as other commenters in this thread mention. Apple refuses to implement RCS on their devices in a way that is compatible with non-Apple devices.
