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..... :)
