Triple Monitor (Dual GPU) xorg problem
I have 3 monitors connected to 2 GPU's and everything is connected and will "work" The problem I'm having is:
When I only have 2 monitors running in twinview off the 1 GPU (1980x1020 & 1600x1050) Ubuntu seems to move the second screen up 30px so the gnome panels line up and there is no distortion or stretching. But when I enable the 3rd monitor as a separate x server (on the 2nd GPU) The third monitor looks and acts as it should, but the 2nd monitor running under twinview, loses that 30px buffer and the gnome panel drops off the screen on it.
Its really strange and I cant seem to figure out why everything works perfectly until I enable a third monitor on the 2nd GPU.
I have included 2 xorg.conf files below (when its working and when its not)
2 monitors enabled on 1 GPU - TwinView looking properly:
