Comment 40 for bug 563100

It seems to be(after trying more configurations of monitors inspired by other bug reports), that the mouse bug only happens when the primary screen(screen 0 which is on GPU 0) is located below screen 1. Every single configuration possible from one column, 4 rows, to any combination of 2x2 comes down to the same thing. You can't have GPU0 located below GPU1. If you change the screens physically, or just change the plugs, you can physically put the monitors how you want, just virtually you have to have GPU0 with screen 0 above GPU1.
