Ok, after messing with this for several days I finally have an 
/etc/X11/xorg.conf.d/10-monitor.conf file that allows allows use of the 
recommended display set up.

[bobg at box10 ~]$ cat  /etc/X11/xorg.conf.d/10-monitor.conf
#    /etc/X11/xorg.conf.d/10-monitor.conf
#

Section "Monitor"
     Identifier    "Monitor0"
     Modeline "1680x1050_60.00"  146.25  1680 1784 1960 2240  1050 1053 
1059 1089 -hsync +vsync

EndSection


However despite selecting 1680x1050 in the Display GUI menu nothing 
changes until I do xrandr -s 1680x1050.

I can probably live with that by adding it to my routine set up 
procedure it would be nice if I could make it come up that way after I 
do "startx."

More help needed there, suggestions and criticism invited.
