title: FBDEV(0): FBIOPUTCMAP: Invalid argument error in Xorg.0.log file
body: <p>My Qt application which plays video shows just a blank <code>VideoWidget</code> window.
  When I remove my <code>Xorg.conf</code> file from <code>/etc/X11/</code> directory on my Debian Jessie 8.2 and restart system, video starts to play, but there is a lack of colors on whole display.</p>
  
  <pre><code>- Kernel version is: 4.1.15-ti-rt-r40 
  - Platform: BeagleBone Black
  </code></pre>
  
  <p>I found this error reported as a bug on <a href="https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-fbdev/+bug/573668" rel="nofollow">this link</a>, but it is very old thread. Is problem in graphic card drivers built for this BB under Debian Jessie 8.2?</p>
