I can connect my Ubuntu 12.04 laptop to my television via HDMI, and use the TV as a monitor.Unfortunately, it's a second monitor; I want it to be an only monitor.(I get annoyed moving the mouse from one monitor to the other. I just want everything to be on the TV. I don't want to have to drag things to the right of my laptop screen to see them on my TV screen.)Please advise me on options, including disabling the built-in monitor.
A particularly annoying aspect of my current configuration is that,even after I drag a window to the TV,if I try to put it into full screen mode,it reverts to the laptop display.
