FWIW, here's what my xorg.conf file looks like:

    $ cat /etc/X11/xorg.conf

    Section "Screen"
            Identifier      "Configured Screen Device"
            Device  "Configured Video Device"
            SubSection "Display"
                    Virtual 3360 1050
            EndSubSection
    EndSection

    Section "Device"
            Identifier      "Configured Video Device"
            Option "AccelMethod" "EXA"
    EndSection

Everything except for the AccelMethod was added by Gnome
(Preferences->Screen Resolution) when I attempted to enable my
secondary screen (which requires the Virtual screen size).

In poking around I did find some comments about AccelMethod causing
slow and flickering windows, and I think I remember that from trying
AccelMethod EXA in the past.  Seems OK now for me, but just in case
here's a link to one:
