Thank you for explaining in detail how you expect the display to behave when using dual head. I agree that the behaviour you describe with using native resolution and limiting the usable area is preferable to the current one. Actually this is more or less what happened for Hardy (you may fire up a LiveCD with that to see how it works on your system). It changed to the current behaviour for Intrepid. I don't know which part of xorg is responsible for this or what the rationale for the change was. See http://launchpadlibrarian.net/17844487/importdump.jpg (from bug 273306) for a screenshot of how the login screen looked back then. The desktop would look like this in mirror mode: http://launchpadlibrarian.net/12354400/screen.png .

That the lid status is not taken into account is a separate issue, and is one of the known issues listed at http://intellinuxgraphics.org/2009Q2.html
