Add plasma-bigscreen role with package built from upstream master
(not yet in nixpkgs, tracking NixOS/nixpkgs#428077).
Changes:
- New role: roles/plasma-bigscreen/ (module + package derivation)
- boxy configuration: swap roles.kodi for roles.plasma-bigscreen
- Keeps all existing functionality: Jellyfin, Stremio, Firefox,
KDE Connect, app-launcher-server, AVR volume control (kodi user)
- Autologins to plasma-bigscreen-wayland session instead of plasma
NOTE: First build will fail with a hash mismatch on the source
fetch — copy the correct sha256 from the error into package.nix.
Some dep attribute names may also need adjustment on first build.
Add remote volume control for the living room media center (boxy) that
controls the Denon AVR through Home Assistant instead of local audio.
- Create plasma-manager-kodi role with custom KDE hotkeys for volume
up/down/mute that execute shell scripts
- Scripts retrieve HA token from KDE Wallet and send API requests to
control media_player.denon_avr_s970h_2
- Add retry logic (3 attempts) and error notifications
- Enable KDE Wallet PAM integration for automatic wallet unlock
- Configure KDE settings: Breeze Dark theme, disable screen locking,
empty session restore
- Add kconfig package for debugging tools
The original implementation had several issues that prevented it from
building:
- Used buildInputs instead of nativeBuildInputs for makeWrapper
- Referenced wrong executable name (jellyfinmediaplayer vs jellyfin-desktop)
- Used wrapProgram which doesn't work with symlinks from symlinkJoin
Fixed by using makeWrapper directly with the correct executable path
after removing the symlink.
Also enabled jellyfinScaleFactor = 1.5 on boxy for UI scaling.
