title: I can't paste what I copied to the clipboard with Vim on Ubuntu
body: <p>I tried yank to clipboard from vim.
  But it does not do it.<br>
  I've attempted with <kbd>"</kbd><kbd>+</kbd><kbd>y</kbd> (also, I tried <kbd>"</kbd><kbd>*</kbd><kbd>y</kbd>)after select copy area in Visual Mode.
  But does not paste copied content when I <kbd>Ctrl</kbd>-<kbd>Shift</kbd>-<kbd>V</kbd> typed on terminal.  </p>
  
  <p>Why it does not paste in terminal despite I yanked to special register?
  <code>clipboard</code> and <code>xterm_clipboard</code>  features are enabled in my vim.  </p>
