I'm no expert but if I was in your shoes I'd be worried about this bit
of your log.

It appears that you aren't specifiying a mode (resolution) in your
xorg.conf file and without EDID information from your monitor the
nvidia-auto-select (whatever that is) can't work, and is defaulting to

That example xorg.conf you quoted also only specifies 640x480 (not
unreasonable for a TV-OUT), but if you're using an LCD display then
you probably want to put the native resolution of your display in

I'd stick with the xorg.conf that you've got, but start experimenting
with putting in different mode statements.
