I'm on Ubuntu and I have projector display to run BGE at fullscreen. But "blenderplayer" doesn't accept "-w" and "-f" at the same time. What would be usefull? What does it do? Example, we have two monitors of 1024x768. We do in terminal in main monitor:

blenderplayer -w -f file.blend

It would start blenderplayer window in the secondary monitor (1025px) and, when finish loading the file, it start in fullscreen.

I could do this with "devilspie", a little program where I can change some window configuration for each program. It makes what I want blenderplayer to do: moves the window and makes it fullscreen. We can get rid of it.
