>Description:
	On an nVidia system with two or more displays, the mouse can move
to the second display, but can't move back to the primary display. This
makes the system nearly useless.

This is described in http://bugs.freedesktop.org/show_bug.cgi?id=12145 and
hads been corrected in the freedesktop git repo.
>How-To-Repeat:
	Start Xorg, move the cursor to the secondary screen and try to
move it back to the primary sceeen.
