In addition to the above, I found that I had to edit the xorg.conf 
file and change the vertical refresh rates
to match the rate that manufacturer says changing the maximum rate 
for the maximum display size that the
  monitor supports In my case 1600x1200 is a 60Hz rate. I also edited 
the Horiz rate to match the monitor I have.
So below is the lines I edited in bold...

Section "Monitor"
     Identifier     "Monitor0"
     VendorName     "Unknown"
     ModelName      "CRT-0"
     HorizSync       30.0 - 110.0  from this to
      HorizSync       30.0 - 81.0

     VertRefresh     50.0 - 150.0  from this to
     VertRefresh     50.0 - 60.0
     Option         "DPMS"
EndSection

Section "Device"
     Identifier     "Device0"
     Driver         "nvidia"
     VendorName     "NVIDIA Corporation"
     BoardName      "GeForce4 MX 440 with AGP8X"
EndSection

Section "Screen"
     Identifier     "Screen0"
     Device         "Device0"
     Monitor        "Monitor0"
     DefaultDepth    24
     Option         "TwinView" "0"
     Option         "TwinViewXineramaInfoOrder" "CRT-0"
     Option         "metamodes" "1600x1200 +0+0; 1280x1024 +0+0; 
1024x768 +0+0; 800x600 +0+0; 640x480 +0+0; 1280x1024_60 +0+0"
     SubSection     "Display"
         Depth       24
     EndSubSection
EndSection

In my case, the above had to be done before re-boot, and after running
$sudo nvidia-xconfig

I didn't do that, so I had to run ubuntu from the CD, editing the 
xorg.conf file from there

So in conclusion, NoOP thanks very much for the vital information to 
get me on the right track. The driver has always been o/k and the 
right one for the card.

I hope this helps others with the same problem, obviously by the 
various posts, this is a common problem,
and I agree with Michael Haney that this problem limits the adoption 
and use of Ubuntu, at least if did for me.

Another issue in this whole thing is that I'm using a usb KVM, and 
that might have hindered the recognition of the monitor (I'm not sure 
about that)
