Integrate Emacs copy/paste with System copy/paste

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.

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.

Is there any way to make this work? Is there another command I can use to access the system's copy-paste buffer?

This works on my machine:

;; CUA OS copypasta even in ncurses mode
(case system-type
  ('darwin (unless window-system
             (setq interprogram-cut-function
                   (lambda (text &optional push)
                     (let* ((process-connection-type nil)
                            (pbproxy (start-process "pbcopy" "pbcopy" "/usr/bin/pbcopy")))
                       (process-send-string pbproxy text)
                       (process-send-eof pbproxy))))))
  ('gnu/linux (progn
                (setq x-select-enable-clipboard t)
                (defun xsel-cut-function (text &optional push)
                    (insert text)
                    (call-process-region (point-min) (point-max) "xsel" nil 0 nil "--clipboard" "--input")))
                (defun xsel-paste-function()

                  (let ((xsel-output (shell-command-to-string "xsel --clipboard --output")))
                    (unless (string= (car kill-ring) xsel-output)
                      xsel-output )))
                (setq interprogram-cut-function 'xsel-cut-function)
                (setq interprogram-paste-function 'xsel-paste-function))))
