When I close my laptop lid, all my screens are turned off (my laptop screen and my LG M237WA monitor).
I'd like to know how do I make it turn off only the laptop screen and keep the monitor on (I want that behaviour for when I want to watch a movie on my monitor and don't want any brightness coming for the laptop screen).
I'm using a HP Pavilion dv4-1290br, which comes with a nVidia GeForce 8400M GTS. I'm using the nVidia driver and it's working perfectly. For my X settings, I'm using TwinView, my laptop is set to 1280x800 and my monitor to 1920x1080.
I hope you guys can help me, for I couldn't find anything so far.
Thank you very much.
