Ok, I put this in /etc/X11/xorg.conf. I get three screens in the correct 
order, but I cannot move windows between the screens. Whatever screen I 
start an application on, that is where it is stuck. If I try, the mouse 
gets to the edge of the screen and moves no further.

When I'm not dragging a window, I can move the cursor around between 
windows without issue.
