Thanks Alexander for your advice. I have now loaded udlfb into the kernel. However no success. Is the screen suppposed turn on (or green or something) once the udlfb kicks in? Or do I need to tinker with my Xorg.conf to get the screen to work? <div> <br></div><div>Timo<br><br><div class="gmail_quote">On 1 June 2010 17:50, Alexander Todorov <span dir="ltr"><<a href="mailto:atodorov@otb.bg">atodorov@otb.bg</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;"> Timo Mohnani wrote:<br> > Hi,<br> <br> Hi,<br> <div class="im"><br> > Please note that my intention is to use only one monitor.

Check if it is<br> enabled, if not you'll have to get it from <a href="http://git.plugable.com" target="_blank">git.plugable.com</a> and compile it.
