  <li>Installed hw_customer_display on posbox</li>
  <li>Installed pos_customer_display on odoo server</li>
  <li>Configured pos proxy address with posbox ip address (192.168.50.36:8069)</li>
  </ol>
  
  <p>My Odoo instance run on ubuntu 16.04 and client running on windows.</p>
  
  <ol>
  <li>Connected customer display on windows machine. But nothing displayed.</li>
  <li>Connect customer display on posbox, then it displays 'P'. Thats all.</li>
  <li>Then i remove <code>hw_scale</code> from <code>/root_bypass_ramdisks/etc/init.d/odoo</code>. and tried again.
  Then the letter <code>P</code> disappeared, nothing else.</li>
  </ol>
  
  <p>Any solution?</p>
