Hi have a laptop and an external display connected via DisplayPort. If I setup Kscreen for the external monitor along with the laptop, next time if I boot with the external monitor disconnected I get only a black screen in the laptop. The workaround I found is to disable the "KScreen 2" in the startup services. But like this, every time I want to use with the external monitor I need to manually start the service. Reproducible: Always This is the output when the dual display is correctly setup: kscreen-console bug ========================xrandr --verbose========================== Screen 0: minimum 8 x 8,
