I went down this rabbit hole about a year ago, and didn’t have much luck. In the end, the best results I was able to get were from Steam’s Big Picture Mode on a Windows device, mostly launching Firefox (might have been Chrome?) with different launch arguments to immitate a smart TV.
Most available software either doesn’t support Linux well, doesn’t support streaming services and outside software, or doesn’t support non-kb&m input methods. You can get two, but never all three. You could try SteamOS, now that its out, but unfortunately my hopes wouldn’t be high for it to have all the apps you needs functioning.
I mean, 10 minutes is pretty optimistic even for a relatively savy user. It took me somewhere around an hour to find and fix everything. On the other hand, it took me and a bunch of people on the Linux support subreddit around 20 hours of troubleshooting to get Linux into a mostly functional state on my PC, at which point I and everyone else had given up, so…
Its been nearly two years since then though, and given what a nightmare Windows 11 is, I guess I’ll have to give it another shot.
