While there were a lot of lines in the log file, not a single
one had, "dpi", in it.  If you want, I can send you the output.

I don't understand a fraction of what you mentioned above, but
one thing kinda puts the kibosh on some of it, is that this is
about the video, while this, and everything else in 14.04 system
settings doesn't work.  __EVERYTHING__

Looks like it's new motherboard time.  **Again**
