My desktop Debian Jessie PC just got a new monitor to replace an old
one that failed. Because the new one is bigger than my previous main
monitor, I have swapped them round so that my bigger 27inch monitor is
the primary one and the original 24inch one has become my secondary.
I have altered my /etc/X11/xorg.conf so that the new one is the Primary
one.

But gdm3 has decided it is going to come up on the secondary monitor.
Once the desktop starts the order of the displays is probably* also
wrong, but of course can be fixed in the display settings
* I say that because the main monitor is numbered 2 and the old monitor
is numbered 1.
Where is the detection of which monitor is which take place, and how do
I tell it to change the order?
You stated that you caught your own duplicate entry for:
Option "Position"
After you said that, I went back and was looking again at your first
email just to see what you were talking about. Now I'm also seeing two
entries for:
Section "Monitor"
This is out of my league so I have to ask.... is it normal to have two
entries for that declaration?
Just thinking out loud..... :)
