In 11.2 there is a file named /etc/X11/xorg.conf that has the following
snipped text included:

***Start of paste:***

Section "Monitor"
  Option       "CalcAlgorithm" "XServerPool"
  DisplaySize  494 320
  HorizSync    30-81
  Identifier   "Monitor[0]"
  ModelName    "SAMSUNG SYNCMASTER"
  Option       "DPMS"
  Option       "PreferredMode" "1024x600"
  VendorName   "SAM"
  VertRefresh  43-75
  UseModes     "Modes[0]"
EndSection

Section "Modes"
  Identifier   "Modes[0]"
  Modeline      "1680x1050" 119.00 1680 1728 1760 1840 1050 1053 1059 1080
EndSection
*** End of paste ***

In the Section "Monitor", the "PreferredMode" "1024x600" is set
correctly, however further down the file in the Mode section the
Modeline is wrong:

Section "Modes"
  Identifier   "Modes[0]"
  Modeline      "1680x1050" 119.00 1680 1728 1760 1840 1050 1053 1059 1080
EndSection

I'm thinking either to change the Nodeline to "1024x768" and deleting
the rest of the line.

Alternatively add a section "Modes, with an identifier of Modes(1) ie:

Section "Modes"
  Identifier   "Modes[1]"
  Modeline      "1024x768"
EndSection

AND then also change the UseModes entry in
Section "Monitor" to

  UseModes     "Modes[1]"

Which is the better option or would both accomplish the same?

There are a few files there namely:
10-evdev.conf
11-mouse.conf
20-synaptics.conf
20-wacom.conf
50-device.conf
50-montor.conf
50-screen.conf
50-vmmouse.conf
60-vboxmouse.conf
90-keytable.conf

None of the above files have anything in them mentioning resolution ie
1680x1024 etc.

Thanks but also figured out given each time I logged on I needed to
reset display :|

As you said earlier, the joy of text being legible is better. Thankfully
I have upgrade my viewing from the older 640x480 and 800x600.

I also had a look at the man page for xorg.conf and it scared me.
