Many thanks to Bill and others who responded.   I think that I have 
determined the "cause" of my grief...

When powering on the card, I had attached *both* the analogue (VGA) and 
digital (DVI) cables to *the same monitor*, an IBM P275 (aka model 6652)

Now the monitor has a switch on its front panel to select between the 
sources.   However the electronics are active (presumably) regardless of 
the switch setting.   So during power-up it is possible that the video card 
became "confused" as to what was expected of it.

Someone hinted at this saying that Windows and Linux occasionally saw the 
analogue and digital outputs as different priority devices.

Suffice it to say that ATM the analogue cable route always works :-)   If 
time permits I will have a look in the kernel config to see if i can 
activate the digital as primary display, but I still think there must be 
some nVidia / aftermarket applet that enables digital from the card as the 
primary.   Hope this may save someone stress in the future.
