title: Cannot start Chromium
body: <p>I am trying to start Chromium 49.0.2623.108 on Ubuntu 15.10 installed on my ODROID-XU4. It used to work all the time but from one day to the next Chromium will not start. When I try to run it via terminal I get:</p>
  
  <pre>
  ~$ chromium-browser

  <p>Any idea what I can do?</p>
  
  <p>I have already tried reinstalling Chromium. That did not solve the issue.</p>
  
  <p>Thanks in advance!</p>
