Dear Folks,

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?
Making a tiny amount of progress: with this configuration, X can start
(a nice change from some previous attempts!), and lightdm shows the
screens in the correct order! Hooray!
But when I log in, the behaviour is rather odd; the VGA appears on the
left; the DisplayPort is next, with the DVI mirroring the DisplayPort.
My xrandr command gets it back into the desired state and order. But
I still wish that I could achieve the same result with xorg.conf as
with the xrandr command, right from the beginning.
Advice most welcome.
