Now an update to all this, the main problem I have now once the
nvidia driver is installed and xorg.conf is configured,
IF I CAN GET PAST THE PASSWORD SCREEN WITHOUT SEEING WHAT I'M DOING
then the monitor comes to life and works fine.
(I was able to do this once).
It still looks like the monitor isn't being identified, and that's
the real problem.
I hooked up a brand new out of the box Dell 2007FP monitor with the
same results and it still wasn't showing up in the xorg.conf file.
The graphics card seems to be guessing as to what's connected, and
setting things up incorrectly.
It looks like a default mode is stored somewhere, and until the
xorg.conf file is run then that mode is in operation. I would guess
that the v sync is too high.
Without a scope I can't tell for sure.
I'm thinking it's now time for a bug report??
Vic
P.S. To all the subscribers whose monitor came up without a problem,
count your lucky stars, this is nasty!!
