I am unable to drive the VGA output.  Symptoms include

* Executing "xrandr" does not mention LVDS or VGA
  (and using --output VGA gives a warning that VGA doesn't exist)

* Pushing Fn-F8 produces a "p" (the keycap of f8 shows in blue a picture
  of a laptop and a monitor) instead of showing the screen on the other
  display.

The xorg.conf file generated by nvidia-xconfig (below)  is fairly simple.
I just added the module section at the end.

Any help would be appreciated.
