This seems less likely to me now. I installed a clean (unstable) system without any recommends enabled, ran octave in openbox on a vnc, and everything worked fine. Is it possible this is a video driver / OpenGL problem on your system? Can you try running octave with LIBGL_ALWAYS_SOFTWARE=1 in your environment? See also https://www.mesa3d.org/envvars.html for other variables to try. Best to use gnuplot if your system has problems with the default GL-based plotting library. -- mike
