</h2>
<p style="margin-left:11%; margin-top: 1em">Security-Enhanced
Linux secures the xdm processes via flexible mandatory
access control.</p>
<p style="margin-left:11%; margin-top: 1em">The xdm
processes execute with the xdm_t SELinux type. You can check
if you have these processes running by executing the
<b>ps</b> command with the <b>−Z</b> qualifier.</p>
<p style="margin-left:11%; margin-top: 1em">For
example:</p>
<p style="margin-left:11%; margin-top: 1em"><b>ps -eZ |

<h2>ENTRYPOINTS
<a name="ENTRYPOINTS"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">The xdm_t
