[EDIT: Although they work, the instructions below are out of date. See https://invent.kde.org/plasma/plasma-bigscreen/-/commit/3841db90f1899d8a90e0a36dc1ba05cdefaea900 for a commit upstream adding a starter script for X11 sessions]
@everyone. To get plasma-bigscreen to run, the following steps need to be taken:
1- Install the package and its deps.
2- Create a dedicated user USER
. Copy the content of https://invent.kde.org/plasma-bigscreen/bigscreen-debos-image-rpi4/-/tree/master/overlays/bigscreen/etc/xdg into $USER
's ~/.config
3- Make this the $USER
's .bash_profile
#
# ~/.bash_profile
#
export PLASMA_PLATFORM=mediacenter
export QT_FILE_SELECTORS=mediacenter
[[ -f ~/.bashrc ]] && . ~/.bashrc
4- You can now launch by loging in with $USER from sddm by running Plasma-X11 or Plasma-Wayland but not Plasma-Bigscreen-Wayland
