Follow-up Comment #2:

Agree with Doug.  With the QT toolkit I have no problems using OpenSUSE and
versions 5.1.1, 5.1.0, 4.4.1, and 4.2.2.

Can you explain how did you install Octave and does your system has special
NVIDIA drivers or alike installed?

What is your graphics_toolkit when plotting?  Only when switching to "fltk" I
get problems, maybe related to bug #43183, but the crash should be avoided by
now.  "gnuplot" works fine either.


graphics_toolkit ("fltk")
xd=linspace(-1,1);
yd=linspace(0,2*pi);
[x,y]=meshgrid(xd,yd);
z=x.*cos(y*y);
surf(x,y,z)
Insufficient GL support
error: unable to plot due to insufficient OpenGL support
