I have three monitors running fine under kde and x11 however I want to add a fourth.

I have two on my discrete gpu and two on my integrated gpu. The two on the integrated gpu are cloning at the resolution of the lowest of the pair I want them to extend my desktop, one monitor is 1280x1024 and the other is 1920x1080. The two on the discrete gpu work like a charm.

I've been reading this guide on how to set them up on the integrated gpu (http://intellinuxgraphics.org/dualhead.html) but I can't seem to get it going. When I look in the log Xorg tells me that it is ignoring all the options I add.

This is the setup I'm using fwiw...is there anything obvious I am missing to get intel x11 dual monitor extended desktop functionality working with my i7-2600. Works fine in windows.
