+==== Testing vcs ====
+Start python and paste the following lines
+<code>import numpy as np, vcs
+id100 = np.identity(100)
+x = vcs.init()
+x.plot(id100)
+</code>
+If you get the kind of errors described in [[https://github.com/CDAT/vcs/issues/393|x.plot crashes with OpenGL2 error]], the drivers on your server are probably not compatible with an interactive use of vcs... The workaround is to **install mesalib and work in //headless mode//** (e.g. without a display)...
+Install //mesalib// with ''conda install -c cdat/label/v81 -c conda-forge mesalib vtk-cdat'' and try pasting again the few code lines above in python. If things work as expected, no canvas will be opened, but you'll be able to save the canvas to a file with
+<code>x.png('test_mesalib')
+x.pdf('test_mesalib')</code>
+Note: using //mesalib// for headless mode work makes it possible to work without an X server, and with no DISPLAY variable defined
