Screen video recording

I’m trying to use some apps to run on KDE NEON, but so far all of them have given me problems.

SimpleRecorderScreen and Vokoscreen show some information, Blue Recorder doesn’t generate the file correctly (only the icon remains). I believe it’s due to some plugins.

Could someone help?

The error messages pretty clearly state that you’re not using X11, and these apps are only supported on X11.
