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.
I tried Jellyfin but had many issues, then tried Emby and it worked first time. Since then I’ve purchased Emby so no point going back. The OP probably has an Emby license so no point changing to Jellyfin now.
