Thanks for your prompt reply! I installed the two modules you suggested and the script no longer complains about it. Good! Unfortunately it still get (new) error messages: (EE) DL(0): Unknown EDID version 146 (EE) DL(0): Unknown EDID version 31 If I ran the same script again, I get the same two error messages, but the version number differs each time. I tried to google this error message but I couldn't find anything concrete. In case this matters, I tried this on an xubuntu 11.04laptop with a GMA4500 GPU, and a xubuntu 10.10 netbook with GMA945. Same error messages (different version numbers). Thanks for your help and suggestion. <div class="gmail_quote"> On Sat, Jul 16, 2011 at 4:28 PM, Marcus Becker <<a href="mailto:marcus.disi@gmail.com">marcus.disi@gmail.com</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;"> Hi, it looks to me you didn't install the display module for Xorg (does Ubuntu still use Xorg or did they switch to wayland?) run aptitude and search for those modules like: aptitude search displaylink and aptitude search void then you can install them via aptitude install <packagename> (usually something like xf86-video-displaylink) xfce4 has a startscript, right? like '/usr/bin/startxfce4' (don't know much about Debian or Ubuntu :/ ) Hope that helps :) Marcus <div><div></div><div class="h5"> On 16 July 2011 20:09, S W <<a href="mailto:partita1234@gmail.com">partita1234@gmail.com</a>> wrote: > Thanks for your script! > > I have a displaylink device from plugable, and when I tried to run this > script on my > xubuntu 11.04 laptop I ended up with the error messages > > (EE) Failed to load module "displaylink" (module does not exist, 0) > > (EE) Failed to load module "void" (module does not exist, 0) > (EE) No drivers available. > > (I've sent along the complete Xorg.1.log for reference).
