Details:

I am running version 3.8.2 of Octave via 32-bit Fedora 21 on my old Toshiba
laptop (Satellite A105-S4284, Intel Core Duo T2050 / 1.66GHz, 1GB of RAM).
When I tried to run the Octave command contour (X, Y, pdf), Octave responded
with the following two lines:
+vertbatim+
libGL error: Version 4 or later of flush extension not found
libGL error: failed to load driver: i915


A Google search on the first line reveals the same error in another context:

I should add that a simple line plot works fine:

x = [0 1];
y = [0 2];
plot(x,y);
