title: can't get the mouse move event from /dev/input/event*
body: <p>I can't get the mouse move event when using the <a href="http://cgit.freedesktop.org/~whot/evtest/tree/evtest.c" rel="nofollow">evtest</a> tools to test the input events .</p>
  
  <p>I just get three mouse events:</p>
  
  <pre><code>left click event: type = EV_KEY, code = 272 (LeftBtn), value=1/0
  
  right click event: type = EV_KEY, code = 273 (RightBtn), value = 1/0
  
  mouse wheel event: type = EV_REL, code = 8 (Wheel), value = -1
  </code></pre>
  
  <p><strong>No mouse move event</strong>.  So where my mouse move event and how to capture it?</p>
  
  <p>ps: Tested on <code>Ubuntu 11.04</code> and <code>Gentoo</code> in VirtualBox-4 with virtualBox-addition installed.  </p>
