I had a similar issue with Ubuntu Gnome after upgrading to 14.10. Had a double mouse pointer, but only on the main screen, not on the two other screens. Disabled screens one by one and renabled them and the problem was solved. Don't know if this is related to your problem, seems more like a gnome problem and as you are using xfce, it might be something else.
