I have Ubuntu 14.04 installed on my laptop. When I have my laptop plugged in to my tv to watch a movie, the screen goes black after exactly 5 minutes. I have to move the mouse, to see I'm at the login screen like this
I'm wondering how can I disable this screen from popping up entirely?
I have already went to System -> Power Management and put everything at Don't suspend / Do nothing. This did not work!!
