[Konfekt]

This tool is really useful, thank you. I am not sure where this error comes from. This is on Opensuse 15.5 with display_switch 1.2.0 due to glibc dependencies:

This is not an issue with the latest release on Ubuntu for the same screen

However, on latest Opensuse Leap after building latest master the issue persists:
