			<content type="html"><![CDATA[<p>Hey and welcome: That error or better warning is about the missing support for OpenGL-extensions. Also the drivers are using DRI3 per default. I&#039;m using myself a ThinkPad X60s for building the 32bit-packages and also as little mobile partner on the way. You can enforce older DRI-configuration within your home-folder in the file .bashrc. Just add the line:</p><div class="codebox"><pre><code>export LIBGL_DRI3_DISABLE=1</code></pre></div><p>In general to say: The videos playing in the browser should be most 360p on that hardware. Everything higher would for sure not the finest enjoyment. The explanation for mpv is exactly that also: It plays not higher until you set this. But then you would have more or less the same. Full-HD (1080p) or 720p is not possible as the graphicscard is not supporting that.</p>]]></content>
