I found a solution after digging for a while! The ATI driver (fglrx) with the Startech adapter allowed me to set one monitor at 3840x1080 resolution (which really was 2 1920x1080 monitors passed through the adapter as one giant monitor). This worked in terms of hardware output, but my desktop was split down the middle between the two DVI outputs because ...

I fixed this for anyone who comes across this issue in the future. Apparently having power to both the integrated and discrete graphics cards was causing each to create a display, resulting in two Built-in displays and mouse flickering. I turned off the intigrated graphics by doing: sudo gedit /etc/rc.local And add the following lines: chown "username" ...

Ensure the Nvidia card which you are running is not restricted ( which includes the Nvidia driver as well) and if the display resolution is still wrong ??

This seems to be an issue with Compiz.

The numbers after the resolution "1920x1080+0+0" are the offset. It's ...
