title: Vim copy-paste to system buffer not behaving as expected
body: <p>I'm having a headache trying to figure out why vim isn't copying to a system buffer.</p>
  
  <p>Here's my workflow:</p>
  
  <pre><code>vim asd
  y1y
  :q
  vim qwe
  p
  </code></pre>
  
  <p>On computerA and computerB, this works as I want it to: the line yanked from the file asd is put into the file qwe.</p>
  
  <p>On computerC, this doesn't work. </p>
  
  <p>All systems are running Ubuntu 8.04. computerA has the vim-full package installed, computerB and computerC have the vim package installed. computerA has xorg installed, is using the fluxbox window manager, and is accessed locally. computerB and computerC don't have X, and I'm sshing into both of them.</p>
  
  <p>I've done a lot of reading and thought it was because computerC was compiled with -clipboard, but I ran vim --version on all three computers and only computerA was compiled with +clipboard.</p>
  
  <p>Am I missing something obvious? I believe the user's .vimrc and the global vimrc files are the same. I can post output of vim --version and contents of vimrc files if that would help.</p>
