title: How do I make Org-mode open PDF files in Evince?
body: <p>In Org-mode when I try to open a link to a PDF file nothing happens. Also, when I do <kbd>C-c C-e d</kbd> to export as LaTeX and process to PDF and open the PDF is generated but not opened. How do I make Org-mode open PDF files in Evince?</p>
  
  <p>I am using Org-mode 7.6 in GNU Emacs 23.3.1 and Evince 3.2.1 in Ubuntu 11.10.</p>
