With the xorg.conf file previously attached, invoking gnome-keyboard-properties causes the system to crash (no screen, no consoles)
After changing xorg.conf using nvidia-settings, setting resolutions to "auto" vice 2560x1600 for screen0 and 1440x900 for screen1, the system no longer crashes and the resolution reset using nvidia-settings. However there are changes in the desktop including different icons on panel, changed backgrounds on panel items, different menu color and some window colors.
