How did you install or build matplotlib? It sounds like you built it from
source, and did not have any GUI dev tools installed. At the very minimum,
matplotlib will build only the non-interactive backends as they don't
require external dependencies (which would explain why you can save images,
but can't show them). Also, what is your OS?
