glxgears does work:

Xlib:  extension "NV-GLX" missing on display ":1187.0".
octave:2> quit

[qss:octave] glxgears
Xlib:  extension "NV-GLX" missing on display ":1187.0".
661 frames in 5.0 seconds = 131.276 FPS
620 frames in 5.0 seconds = 122.944 FPS
==============================

But, I agree that the display ":1187.0" is suspicious.
But, I also get the failure without use of NX.  This happens on
a DSL line using ssh.

I just tried a slow DSL connection:
octave:1> plot(1:200)
octave:2> print("testpdf.pdf")
GL2PS error: Bad file pointer
panic: Segmentation fault -- stopping myself...
attempting to save variables to `octave-core'...
save to `octave-core' complete
Segmentation fault (core dumped)

So, the NX Xlib:  extension "NV-GLX" missing on display ":1187.0".
is not the problem.  The evidence is definitely timing.  I can ssh
to/from machines that are on 1GB without problems.  But at least
2 machines on (pretty slow) DSL fail as above.
