as the title says, i want to close the lid and have the laptop screen open. i had it running like that fine without trying to achieve this, just how it was when i first plugged the hdmi cable and connected the second monitor. but, out of the blue it changed. now, whenever i close the lid the screen goes off, so it pushes my desktop to the second monitor (and since there is no other monitor on it becomes primary). How can i stop this? Thank you in advance!
