I have my laptop set up to run a second monitor with Nvidia as the driver. When I unplug the monitor and take my laptop with me, it does not reboot as a single monitor machine. The second monitor is still a part of my screen and some of my applications (Libre Office Impress) are opening in the non-existant monitor. My Nvidia X server settings does not show the second monitor and there is no way to disable it that I can see. I've been googling answers for hours with no luck... Anyone here have a fix?
