Hi. I have a nvidia optimus laptop, so if I want use external screen, I need execute intel-virtual-output. When I connect the HDMI, KDE show me the popup to change the screen configuration, so, KDE detect when the screen is connect, but, I need execute intel-virtual-output manually for the external screen be available. So, if I could set a custom command (intel-virtual-output) when KDE detect change in external screens, all process could be transparent.
I don't think this is a feature we want to support, sorry. Why do you need to run `intel-virtual-output` when using an external screen?
