So, I have embeded system that is connected to a TV with HDMI.
I have problems when TV turns off, xorg acts like it's unplugged and my opengl program loses controll and starts to render at some insane FPS.
I wan't you to configure Xorg so it acts like TV is plugged in all the time, regardless if it's on or off. In other words, I want system to be display-agnostic, by defining a specific display.
I'm using xorg 1.13, updated ubuntu 12.10 and fglrx drivers. You have to make this working only with this system. I will let you ssh in and help you with all details you need.
