title: Vim syntax Highlighting
body: <p>I have installed vim in Debian 6. I am trying to change color scheme and enable syntax highlighting. But it's not working. I added <code>set background=dark</code> in <code>.vimrc</code> file. But white background is displaying. I wonder what went wrong?</p>
  
  <p>Here is my <code>.vimrc</code> file: <a href="http://pastebin.com/8k2gpWDh">http://pastebin.com/8k2gpWDh</a></p>
  
  <p>I installed <a href="http://www.vim.org/scripts/script.php?script_id=3478">robokai</a> colorscheme which has dark background. But the background looks white instead dark. Other colors of colorscheme working.</p>
