Well, I have never knowingly done anything with matplotlib at all! So shouldn't the tests work? It's not as if I have some strangely customised setup. The sage install has created $SAGE_ROOT/local/lib/python2.7/site-packages/matplotlib-1.3.1-py2.7-linux-x86_64.egg/matplotlib/mpl-data/matplotlibrc which sets the backend to tkagg. I tried copying that file to the suggested place ~/.config/matplotlib/matplotlibrc (the directory existed but was empty) and changing tkagg to pdf but the test still gives the error about failing to connect to localhost:12.0 John > > François > On 30/07/2014, at 22:21, John Cremona <john.crem...@gmail.com> wrote: > >> On 30 July 2014 11:10, Francois Bissey <francois.bis...@canterbury.ac.nz> >> wrote: >>> Not exactly.
