The reason i would doubt that it is the graphics card in my laptop is
that I cannot get an image to project to the external monitor even
when I connect it to a different computer. A few days ago I was able
to use the monitor with either laptop, now I cannot get an image to
project to the monitor from either laptop. It would seem unlikely to
me that both laptops have failed graphics cards.
However, I did the sequence of commands that you suggested. The
Xorg.0.log file no longer shows the warning message I mentioned
before:
(WW) Sep 16 15:07:43 NVIDIA(GPU-0): Unable to read EDID for display device CRT-0
However, it no longer detects the monitor connected to the VGA port. Curious....
