I work on external monitor all the time with closed lid.
However sometimes I need to use the built-in camera for Skype, thus I open the lid, select "detect the display", launch Skype, call and select video.
The problem: in order to get the external monitor working again, I have to shut the lid again. The computer goes to sleep state, and then I have to power it up with keyboard or mouse.
Is there anyway that I could switch only to single external monitor with lid opened up. In other words if I have 2 displays running, how can I shutdown the lid and switch to the external one without closing the lid?
I am not looking solution like blacking out the screen (dimming) or so.
