Basically, trying to run a program that uses x graphics, with the x being 
exported to this machine.  Any other graphical output program runs fine, 
but not Linuxcnc.

I am dead in the water because I'd have to dress and walk across the back 
yard & up the hill to get to the building where the machine is just to 
test my code.  At 2AM, doable without dressing, but the noise of the 
doors will wake my lady.  So I just say to heck with it and go find my 
bed, not knowing if what I just wrote works or not.  Being an 81 yop 
diabetic, I am up at 2 or 3 hour intervals in the night anyway.

Other than to prove the x remoting works, nothing.

A chance, I occasionally expound on something there. Not recently though.
