Hello.
this may seem weird, but steam bigpicture mode is great for a tv. you can make webapps for stuff like netflix, youtube, whatever with google chrome.
i think kde has/had a big mode for tvs, not sure if its still developed. never used it bc i dont much like kde.
yeah thats exactly what i loved about ubuntu studio. it has basically every creative app you can find for linux.
in the same vein, i was looking at the commodore vison os, and that too is packed to the gills with included apps, more of a focus on the gaming aspect. the interface is god awful tho lol.
as a long time linux user, im happily on manjaro, but flirting with nixos.
the new nas has jellyfin in docker, the old one is just a freebsd desktop with jellyfin installed via the regular package manager
leave em alone. but be around when/if they decide theyre tired of ubuntu.
honestly ubuntu studio is an incredible way for first timers to try out a ton of software
i use arch btw
