glxgears works.   And, the "old" build from 24 November works now and it 
worked
when the current build was failing (See below!!).  Also,
what I meant by "no plot"  the frame came up (with A  G along the 
bottom), but the
data and axes were not drawn.

However, I have real news.  Now it works.  I really have no idea what fixed
it.  I am running in the same NX session as before: I just disconnected and
reconnected --  this brings back exactly the state when I disconnected.
The only thing I did was run glxgears!!!

My experience with openGL is that it does lots of neat stuff, but it has 
some
deep mysteries.   Also, I have an application which causes openGL to 
cause X11
to segfault -- end of X11.   I documented this fully and sent it in, but 
they just
decided it was too hard, or not worth fixing.

Back to Octave.  If it fails again I will try to figure something out before
it starts working again.  As I think of what could have gone wrong, I 
suspect
X11 as much as openGL or Octave...
I looked around my server system: nothing obvious in system logs, etc.

Thanks again,
