http://ubuntuforums.org – I have a Asus hd monitor plugged into my nvidia card and a monitor plugged into my intel graphics card. I have this setup because the second monitor is an older apple cinema plasma display with a dvi interface. It's interface will not fit next to my Asus monitor on the gpu. In windows I can get a dual monitor setup no problem. My motherboard is a Z68 Gigabyte. (Hardware)
