I thought I’d follow up on this. I’ve since switched my Rapsberry Pi 4 to an x64 mini PC running Manjaro. My assumption is that most of what I share here will apply to the RPi4 as well.
A maintainer of the AUR packages for bigscreen shared the following steps to get bigscreen at least loading and not presenting a black screen. (I’ve paraphrased his comment’s contents and modified the first command for Manjaro. You need the AUR enabled, obviously. See also his follow-up comment.)
- pamac install plasma-settings-git
- Add the contents of overlays/bigscreen/etc/xdg · master · Plasma Bigscreen / Plasma Bigscreen Raspberry Pi4 DebOS image · GitLab to /home/$USER/.config/
- Add the following to the user’s .bash_profile
export PLASMA_PLATFORM=mediacenter
export QT_FILE_SELECTORS=mediacenter
As he says:
You can now launch by [logging] in with $USER from sddm by running Plasma-X11 or Plasma-Wayland but not Plasma-Bigscreen-Wayland
These changes have caused bigscreen to load the DE for me (no more black screen!), but the AUR user kihanos, who provided these changes and helps maintain bigscreen, said:
So, I finally got it to run as expected without Mycroft nor CEC support. Things are more complicated than I thought.
I have tried to tackle some CEC stuff, and here’s where I’m at:
This link overlays/bigscreen/etc/skel/.config/autostart-scripts · master · Plasma Bigscreen / Plasma Bigscreen Raspberry Pi4 DebOS image · GitLab provides some necessary setup steps for bigscreen to run automagically.
I ran:
group add uniput
usermod -a -G $USER uinput
mkdir /home/$USER/.config/autostart-scripts
git cone https://invent.kde.org/plasma-bigscreen/bigscreen-debos-image-rpi4.git /home/$USER/.bigscreen
cp /home/$USER/.config{,.bak}
rsync -avhP /home/$USER/.bigscreen/ /home/$USER/.config/
pip3 install wheel
pip3 install python-uinput
pip3 install cec
But the final pip3 command errors with the following:
pip3 install cec error
pip3 install cec
