This has turned into a total nightmare trying to get simply get my laptop to display only on my external monitor WITH THE LID CLOSED! I chose "Do Nothing" for on lid close in the power manager in cinnamon, but but every time I close the laptop lid the external display goes off. So I installed dconf-tools and manually changed the settings there as well. I also verified the settings saved by rebooting the laptop and running dconf-editor again. However, when I close the laptop lid the external display still goes off. Does anybody know how to make this work? Laptop is Dell XPS 14Z and is connected to the external display via HDMI. I don't know anywhere else to try and change the settings. The laptop will be on a shelf when connected to the external display so I do not want the laptop lid open. Suggestions? It is things like this that really annoy me about Linux. I am not having trouble running apps, etc., but it seems the littlest things that should be simple turn into a 2 hr ordeal. Thanks for any assistance. Also forgot to mention I'm on the 64-bit version of MInt 13 with Cinnamon Desktop.
