As I said earlier, it does make a difference. I'm required to make the screen black, but not turn the monitor off. If I'm using the term "idle" incorrectly, I apologize. But, what I'm getting from...

100% right Jim, that's exactly what I need to do. Basically, we're rewriting a Windows application to run on Linux, so I'm supposed to emulate that functionality of being able to go idle and then...
