I think I found the root of the problem, now I need to figure out how to fix it.

Running not in recovery mode I ran xrandr.
It seems to be using two displays,
I don't know where LVDS1 comes from or how to get rid of it, but I think that is the goal for now.

I copied the xorg.config from y previous drive bit it doesn't seem to be read or do anything.
Code:
emc@cnc ~/Desktop $ xrandr Screen 0: minimum 8 x 8, current 2560 x 1024, maximum 32767 x 32767 LVDS1 connected 1280x800+0+0 (normal left inverted right x axis y axis) 0mm x 0mm 1280x800 58.1*+ 1024x768 60.0 800x600 60.3 56.2 640x480 59.9 VGA1 connected 1280x1024+1280+0 (normal left inverted right x axis y axis) 330mm x 270mm 1280x1024 60.0*+ 75.0 70.0 1280x960 75.0 60.0 1152x864 75.0 1024x768 75.1 75.0 70.1 60.0 832x624 74.6 800x600 72.2 75.0 60.3 56.2 640x480 72.8 75.0 66.7 60.0 720x400 70.1 VIRTUAL1 disconnected (normal left inverted right x axis y axis) emc@cnc ~/Desktop $

You might be able to disable the LVDS in the BIOS.
In the "monitors" control panel I imagine it thinks there is an LCD display connected?

I moved the drive to my home PC and ran xrandr again.

It gives a different result. Only one display.

I wonder why that would be.
Code:
emc@cnc ~ $ xrandr Screen 0: minimum 320 x 200, current 1024 x 768, maximum 8192 x 8192 DVI-I-1 connected primary 1024x768+0+0 (normal left inverted right x axis y axis) 0mm x 0mm 1024x768 60.0* 800x600 60.3 56.2 848x480 60.0 640x480 59.9 DP-1 disconnected (normal left inverted right x axis y axis) DP-2 disconnected (normal left inverted right x axis y axis) emc@cnc ~ $

Good news, I figured out a way to solve the problem.

The following command will temporarily get rid of the unwanted display named "LVDS1".
Code:
xrandr --output LVDS1 --off

If that line is added to the following file:
(insert it before the last line)

/etc/mdm/SuperInit

Now the problem seems to be fixed permanently.

Andy Pugh thanks for you help, without it, I would have retreated back to my old drive and would have abandoned my further goals.

Now to take another swing at the tool changer.
