making one screen "display only" on RHEL
I have an interesting challenge. I need to set up a 5 head RHEL system, and make it so the 5th screen is "display only". It needs to be made so that the mouse can't even go on to that screen, and it accepts no keyboard input. There will be a special in-house app we have displaying on that screen, and it is not to be touched. Is there a way to keep the cursor from going to that screen? It seems like that should be possible, but for all my googling I can't find any leads at all. Any help would be greatly appreciated!
