Nvidia graphics under Ubuntu

Solved graphics issues (nvidia-340) in Ubuntu once and forall with the following kind guide:


Q: I cannot seem to run the examples listed i. e. here. How do they work?
A: First look after using the right modules: (use 'midje.repl) and also (require '[midje.checking.core :as checking]). The trick is then, each time a wiki page speaks of "checker" and lists examples of this concept to still wrap those example inside (fact ...) i. e. (fact "abc" => (contains "bc")). That's all there is to know.
