It happens very quickly.  There is a brief flash of color, and perhaps a few
lines of text, then an interminable black screen with no response to
keyboard/mouse input.

I'm familiar with the dmesg output at boot time.  I see that when I choose
to boot into recovery mode from the grub menus.  When the scrolling text
stops, I'm left with what I thought was a frozen screen, but it turns out to
be login, without a prompt, waiting for me to provide the root password.
Once I submit the root password, I have a command line interface to a
reasonably functional Debian system.

What I have discovered thus far, is that Debian wants to launch X11 by
default, instead of the command line UI.  That appears to result in a black
screen with a frozen system.  

At this point, I have no idea of the correct way to boot to the command line
interface, so I temporarily renamed lightdm, and now it boots to the command
line interface apparently after X11 fails to launch.  So, it appears that it
is X11 that has possible issues with the hardware or is misconfigured.
Perhaps there is something in X11's /var/log file that will provide a clue
about why it was failing to successfully launch.

So, it appears that grub is correctly configured after all.  

What is the correct way to configure the system to boot to the command line
UI instead of X11?  Do I need to edit things, or add files to, /etc/rc.d
someplace?  Or is there a higher-level way to tell systemd that I prefer to
manually launch X11?  

I'm aware that running the startx script is a reasonable way to launch X11
when I want it, but I'll have to diagnose its issue(s) first.  My past
familiarity with AT&T Unix from the early '80s through the '90s was pre-X11,
so I'm going to have to learn how to administrate X11 now I suppose.  

I sincerely appreciate your kind efforts in guiding me.  I gives me the
motivation to continue spending the time to get Jessie up on the new Udoo
X86 platform.
