I have been unable to get both heads of my nVidia 7800GT to work. I start with the output of 'Xorg --configure' and add the second Monitor and a display set for a 2560x1024 display. I get the proper display on one monitor and the other just displays "Cannot Display This Video Mode". I add "Option Dualhead" and get no screens found. I added "Option FlatPanel" and got "Cannot Display This Video Mode" on BOTH screens. Can anyone give me a clue as to how to configure this for Xrandr operation? I'm sure I am missing something obvious. I should mention that the displays are LED panels, but they use VGA, not DVI connectors, so I have DVI to VGA adaptors on both ports. I can supply logs of the various configurations. -- R. Kevin Oberman, Network Engineer Energy Sciences Network (ESnet) Ernest O.
