Hi, I use jessie (testing) on a lenovo T530, I have a docking station with a connected monitor. I'd like to be able to close the lid of the laptop when it is on the docking station and having the system juste see that the laptop screen is not there anymore, thus having then only the external monitor, then see again the laptop screen if I open the lid. Is it possible ? If it matters I use KDE. Thank you.
