The drawing tablet thing is a known issue that's already fixed in nightly. Please post the logs from the nightly build.

Ok, that all looks correct. What are you expecting to happen?

The touchscreen is not initialized until a client connects and send a native touch event (note: iOS and Android clients do not currently send native touch events, only native pen events).

Edit: Also you don't have the proper FFmpeg and Mesa version installed, which is why no working encoders are found. See https://rpmfusion.org/Howto/Multimedia

Thank you very much! I successfully tested touchscreen input using moonlight android, but it seems that wayland apps does not accept touch input, Only apps using xwayland react to touch event.

And touchscreen device does not appear in KDE systemsettings.
