I would like to write some C/C++ program to controll monitor/projector attached to my computer. I've googled around, but I couldn't find almost anything that would lead me in some direction.

Do you know where I can learn about it?

What I would like to do is to write "Hello world" on an external monitor. It would be also nice to have some "monitor emulator" that will act as physicaly attached monitor (or to write program to emulate it). I'm not sure if it is possible. I couldn't find anything like this.

I'm working on Ubuntu 9.10 with Gnome.
