Well, I successfully dual-booted my Latitude D430 with Vista and Gutsy. Then tried to configure dual display (extend the screen to an external lcd) through the Screens&Graphics app and clobbered the content of xorg.conf (fortunately, last good setup was backed up in xorg.conf.N). Any idea how to do this with different resolutions on screens? This worked out very well previously on a Dell D820 with nvidia-settings video driver software. This time the video card is an Intel 810i GM.
