I am having problems getting this to work correctly. By default, after installing the card, the system displays the image on both monitors, but they are identical images. I have tried many of the suggestions in previous threads but with no luck. The following is the test XF86Config file. When ever I use this file as the current config, the primary monitor works, but the secondary just shows the image of the first, I can't move the mouse to that screen or even see a cursor like I can with the default config.
