Thanks for the hint Mike.

$ xvfb-run -a ./run-octave --eval "available_graphics_toolkits ()"
libEGL warning: DRI2: failed to create any config

  [1,1] = fltk
  [1,2] = gnuplot
  [1,3] = qt
}

$ ./run-octave --eval "available_graphics_toolkits ()"
octave: X11 DISPLAY environment variable not set
octave: disabling GUI features
ans =
{
  [1,1] = gnuplot
}


Thus I should replace all "make" by "xvfb-run -a make" even for the MXE
builds?

As solution, I suggest, jwe, we should publish your tarballs with nicer
pictures today to keep the release date.

I restart my builds from scratch and upload asap.  For anyone who cannot
wait another day for the Windows installers, can refer to
https://octave.space for almost nice builds.
