<img alt="Display bug" src="/images/bug.png" />
<p>As you can see at the image, the mint detected the display but mirrored it in a crazy way that works but doesn't at the same time. If you try anything and doesn't get working, or just wanna skip the whole job of configuring complexes text files, give a try to <a class="reference external" href="http://willem.engen.nl/projects/disper/">Disper</a>. Download the latest version.
Extract it on any folder, and make install it (on the extracted folder).</p>
<div class="highlight"><pre><span></span>make install
</pre></div>
<p>After that, you can start using it... There are a few options that will serve you well.</p>
<div class="highlight"><pre><span></span>disper -e <span class="c1">#extend your display</span>
</pre></div>
<div class="highlight"><pre><span></span>disper -c <span class="c1">#clone your display</span>
</pre></div>
<div class="highlight"><pre><span></span>disper -s <span class="c1">#only your external display</span>
