The odroid64 already has an x system running as soon as I log into the 
odroid64.  Its $DISPLAY is :0

I'm at a dead end, I think I have all the i's dotted and the t's crossed 
but I cannot get a single byte across the link because the pi cannot 
open the display on the odroid64.

I suspect it may be the display number, which is :0 on the instance 
running on the odroid46, automaticly brought up when I log into the 

and an echo $DISPLAY on the pi shows: (after I've done the commands)

I have a hunch that is the error. Or at least the next hurdle.

The .Xauthority file on both machines had grown to several kilobytes, so 
I blew them away, then discovered I needed to touch them, x couldn't 
create the missing file.

I figured I'd start with a clean slate on both SBC's that way.

And I did get a round tuit and put a power cord in the two pads next to 
that worthless coax connector, so now the odroid64 has solid power. 

Thanks Peter.
