SUMMARY

Running the nightly Flatpak on KDE Neon User Edition fails.

STEPS TO REPRODUCE
1. Install Flatpak from https://origin.cdn.kde.org/flatpak/plasma-keyboard-nightly/org.kde.plasma.keyboard.flatpakref
2. flatpak run org.kde.plasma.keyboard

OBSERVED RESULT

user@computer:~$ flatpak run org.kde.plasma.keyboard
qt.qpa.wayland: qtvirtualkeyboard currently is not supported at client-side, use QT_IM_MODULES=qtvirtualkeyboard at compositor-side.
pci id for fd 15: 10de:1f9d, driver (null)
kmsro: driver missing
qrc:/qt/qml/org/kde/plasma/keyboard/main.qml:99:13: TypeError: Cannot read property 'aspectRatio' of null
Failed to initialize input panel-shell integration, possibly because compositor does not support the layer-shell protocol
ASSERT failure in Q_UNREACHABLE(): "Q_UNREACHABLE was reached", file /run/build/plasma-keyboard/src/main.cpp, line 124


EXPECTED RESULT

The keyboard works

Plasma Keyboard is not a regular application, its handled by kwin. You cannot start it using flatpak run. 

Instead you need to select it in the systemsettings.

I don't see how its different? 

In case I misunderstand please feel free to reopen.
