Original Multi-monitor setup

I got the approval from my company to provide these screen shots.  The three screen shots are as follows.

1) The original running on the standard windows XP OpenGL driver using a Nvidia Quadro FX 3700.  You can clearly see the dual monitor support with the screenshot.
2) The Mesa3D version running in a virtual machine running windows XP and Mesa3D OpenGL driver.
3) Video modes used in the virtual machine environment.

As you can see in #2 the graphics for the first screen are on top of the graphics for the second screen.  I emphasized this by shrinking the first screen which in turn shrank the rendered graphics on the second screen.

The graphic issues you see in #2 will be filed as a separate bug as I believe it is a separate issue than the multi-monitor issue.

Mesa isn't where this type of thing is handled. You were probably having an issue in X somewhere. Given the age of this bug I'm just going to close it rather than reassigning.
