I can use dual head extended desktop even without adding "Virtual" in xorg.conf. I have 1280x800 display in laptop and 1280x960 external monitor. I suppose that there should be appropriate login screen in both monitors, but in the laptop display only upper part of the login screen is shown, if external monitor is connected.
