title: fluxbox couldn't connect to XServer - CentOS 6.4
body: <p>I'm setting up some new VNC servers.  I already have this setup working with CentOS 6.3, although I'm not certain that this difference is the real problem.</p>
  
  <p>One of the window managers I'm making available is fluxbox, but when I start it, I always get the following: <code>Error: Couldn't connect to XServer</code>.  Here's my setup:</p>
  
  <pre><code>fluxbox: fluxbox-1.1.1-5.el6.x86_64
  vnc    : tigervnc-server-1.1.0-5.el6_4.1.x86_64
  OS     : CentOS 6.4
  </code></pre>
  
  <p>Note that I can start other window managers: Gnome, KDE, openbox, xfce4, etc.</p>
  
  <p>I gutted my ~/.vnc/xstartup script so it only loads an xterm.  Then, I tried running <code>startfluxbox &amp;</code>, but still got the error.  Obviously, VNC is working, since my xterm opened up OK.  I can start firefox, another xterm or other app requiring X, and even fluxbox comes up, but it is worthless in its current state, since it is not connected to the X session.</p>
  
  <p>What is fluxbox looking for?  Are there some log files I can look at to give me some clues?</p>
  
  <p>Thanks,
  David</p>
