This is expected as a result of the absence of any video config options on
kernel cmdline. I just wanted to confirm this is what was actually occurring.

Sure enough, the one I was working under lost graphic display.  So I immediately created two more.  Having a global solution, does have some risk.  If I blow it, I could loose all displays.  But the need for this solution is necessary, the screen is only readable with a magnifying glass at full resolution.

Let's skip that methodology for now. Instead, ensure that ~/.screenlayout and
any other Xorg config changes you put in $HOME do not exist (rename, move,
etc.), then, save the following to /etc/X11/xorg.conf:


and restart *dm or reboot, login, then report results. If you don't get what
you expect or want, pastebin the resulting Xorg.0.log.

There's supposed to be for Intel (worksforme), but let's defer that until
later too....
