title: Integrate Emacs copy/paste with System copy/paste
body: <p>I have (cua-mode t) in my .emacs, so that C-c is copy and C-v is paste just like most other programs on my desktop (Ubuntu, Gnome, Linux). However, Emacs does not seem to share the clipboard/copy buffer with other programs.</p>
  
  <p>For example, if I C-c in Firefox I can S-C-v to paste into a terminal or C-v to paste into gedit. However, if I C-v (or C-y) in emacs, I do not get what I copied from Firefox.</p>
  
  <p>Is there any way to make this work? Is there another command I can use to access the system's copy-paste buffer?</p>
