title: electron blank screen on raspberry pi 3b
body: <p><br>
  <br>
  I want to use electron js in order to build a desktop app, which will run on a Raspberry Pi 3B. I'm developing the app on my macbook. There, I can use the command <code>electron .</code> without any problems. If I try to start the electron-quick-start app, the following happens:
  <br></p>
  
  <ul>
  <li>I execute the following command in the terminal in the directory of electron-quick-start: <code>electron .</code></li>
  <li>The electron window opens with the correct background color</li>
  <li>No html content is shown</li>
  </ul>
  
  <p>I tried building the app with the electron-packager for the armv7l architecture and running it on the raspberry pi. This works, but it is a tedious task to build the app every time to test it on the Raspberry Pi. </p>
  
  <p>Do you have any ideas, why the <code>electron .</code> command doesn't work?</p>
  
  <p>UPDATE: I started debugging the main.js file:</p>
  
  <pre><code>webContents.on('did-start-loading', function() {
     console.log('did-start-loading');
  });
  webContents.on('did-stop-loading', function() {
     console.log('did-stop-loading');
  });
  webContents.on('did-finish-load', function() {
     console.log('did-finish-load');
  });
  webContents.on('did-get-response-details', function(e, status, newUrl) {
     console.log(newUrl);
  });
  </code></pre>
  
  <p>And I get the following response:
     did start loading
     did stop loading</p>
  
  <p>UPDATE 2:
  I uncommented the <code>mainWindow.webContents.openDevTools()</code> line, so actually the chromium dev tools should start, but they don't...</p>
  
  <p>Thanks for your help.</p>
