title: Ubuntu 16.04 screen completely freezes only mouse moves
body: <p>Ever since I have upgraded my laptop (<a href="http://www.filedropper.com/hardinforeport" rel="nofollow noreferrer">Click here for hardware specs.</a>) my screen usually freezes. Mostly in chrome or Firefox browser. I am pretty sure this is a Nvidia driver problem but I can't seem to find the solution. I am running a Nvidia Quadro K2100M.</p>
  
  <p>I am currently running Nvidia 361.42. I have tried using open source Xorg server without any luck.</p>
  
  <p>The only solution I have found so far is forcefully turning off the computer by holding down the power button.</p>
  
  <p>Things that I have tried:</p>
  
  <ol>
  <li>I got keyboard input</li>
  <li>I cannot switch to another terminal to restart <code>lightdm</code></li>
  </ol>
