    <description>&lt;P&gt;Hello Amy,&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;thanks for your reply &lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;My post was meant to file a bug report to owners of intel graphics drivers since&lt;/P&gt;&lt;P&gt;as you may check at this address:&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;        &lt;P&gt;     &lt;A href="https://software.intel.com/en-us/forums/graphics-driver-bug-reporting"&gt;https://software.intel.com/en-us/forums/graphics-driver-bug-reporting&lt;/A&gt; Graphics Driver Bug Reporting&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;for a consumer (i'm not a game developer, although i'm an IT guy) this seems to me the correct forum&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;to ask for support. My report is not related to intel NUC systems nor to CentOS,&lt;P&gt;(those are additional details to help reproduce the problem) but to intel linux drivers of that specific&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;version (&lt;B&gt;/message/360116# 360116  2.99.917) running on&lt;/B&gt; supported hardware (Intel® HD Graphics 6000).&lt;P&gt;&lt;/P&gt;&lt;P&gt;Any chance to have a pointer to working instruction on how to report a bug to owners of intel graphics drivers for linux?&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Thanks for your support,&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;-m&lt;/P&gt;</description>

      <description>&lt;P&gt;Hello, metatype:&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;  Intel does not test and validate Intel® NUC on Linux; however we know that a lot of NUC owners are using it successfully on many different Linux distros. &lt;/P&gt;&lt;P&gt;Intel suggests you check your Linux distro's website and forums at &lt;A href="http://www.linuxforums.org/"&gt;http://www.linuxforums.org/&lt;/A&gt; Open Source and Linux Forums for peer assistance with this issue.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;For further reference &lt;A href="http://www.intel.com/support/motherboards/desktop/sb/CS-034034.htm"&gt;http://www.intel.com/support/motherboards/desktop/sb/CS-034034.htm&lt;/A&gt; Intel® NUC — Supported Operating Systems.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Regards, &lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Amy. &lt;/P&gt;</description>
