I've been using various dual screen setups for more than ten years now, and 
*never* changed any of the options shown there. I think they are useless, and 
I don't see how changing any of these would improve the desktop experience. 
For the minority who thinks they really do need it, just disabling Xinerama 
probably makes more sense.
