Dear Etienne,

Thank you for taking time to share your thoughts.

Sorry, perhaps I have been insufficiently clear on what my aim is.

1. If you look at the xrandr command (which, as I said, works like a
    charm), you will see that I want to put the DisplayPort-0 in the
    middle, the DVI-0 on the left, the VGA-0 on the right.

2. Automatic configuration works just fine, with DisplayPort-0 on the
    left, DVI-0 in the middle, VGA-0 on the right.  But I don't want
    that order, because the DisplayPort-0 monitor is new and fabulous,
    while the other two monitors are old and not so good.

3. I am trying to make the xorg.conf do what the xrandr command does,
    when X starts up.

Perhaps I need to specify that the DVI-0 should be on the left?

Hmm: here's something from Xorg.0.log:
[ 16343.789] (==) Using config file: "/etc/X11/xorg.conf"
[ 16343.789] (==) Using system config directory "/usr/share/X11/xorg.conf.d"
[ 16343.789] (==) No Layout section.  Using the first Screen section.
[ 16343.789] (==) No screen section available. Using defaults.
[ 16343.789] (**) |-->Screen "Default Screen Section" (0)
[ 16343.789] (**) |   |-->Monitor "<default monitor>"
[ 16343.789] (==) No device specified for screen "Default Screen Section".
         Using the first device section listed.
[ 16343.789] (**) |   |-->Device "ati-5450"
[ 16343.789] (==) No monitor specified for screen "Default Screen Section".
         Using a default monitor configuration.

So do I need to make a Screen section?
