</div>which should reply with an error in XML format.<br></div><div>So it seems Apache/QGIServer do not like my DISPLAY parameter.<br></div><div><br></div>Any hint ?<br></div>Would it be simplier to test this in a real server with no existing X Server by using Xfvb ?<br>

Hi<br>
<br>
You might also want to consider using Xfvb as a 'fake' xserver.<br>
<br>
