I don’t want to use Osmc or LibreELEC. What I’m going for is something like Android TV (tried using LineageOS but that didn’t work out for me).
I was interested in something like Plasma Bigscreen but most of the tutorial is about 4 years old and point to using an old image.
I installed the Debian package. After that, I logged in and set Automatic login, and switch the session to Plasma Bigscreen (x11). After applying and a reboot, it launched Plasma Bigscreen but some widgets (like the audio, KDE Connect) froze when clicking on them.
What do you recommend? I prefer to use a Raspberry Pi.
Aside from Edge, the Netflix app will also work. Basically, Netflix doesn’t send you a 4k stream without PlayReady or an equivalent level of DRM, which native apps typically also will (though your experience may vary on Android if you buy cheap Chinese phones).
There are addons that will get you 1080p on Linux instead of the 720p that you get by default. They break every now and then, but at least full HD is possible without too much effort.
