I have an acer Aspire v3 722G with Debian 8 and Gnome Installed. Lately I received a second external Monitor. The Laptop has one HDMI and one VGA port. I now have connected one Display (1080x1024) to the HDMI-Port. The other Display (1680x1050) is connected via VGA. When the Laptop is closed, everything works fine (the two external Display are used and the Laptop display isn't).I now want to use the Laptop display too. When I open the Laptop and activate the screen as a secondary Display, all two external displays and the laptop display goes blank.When I Ctrl+Alt+F1 into the shell, it shows up on all three screens.What do I have to do to get all three Displays Working?
