With arandr I have configured it and I save a shell script (<tt>/usr/share/setdualmonitor.sh</tt>) to obtain the desired result: <tt>#!/bin/sh</tt><tt> </tt><tt>xrandr --output DP3 --off --output DP2 --off --output HDMI2 --off --output HDMI1 --mode 1680x1050 --pos 1920x0 --rotate normal --output DVI-I-1 --mode 1920x1080 --pos 0x0 --rotate normal --output DP-1 --off --output VGA1 --off</tt><tt> </tt> I want to make it the default behaviour, so I added to /etc/lightdm/lightdm.conf <tt>[SeatDefaults]</tt><tt> </tt><tt>user-session=ubuntu</tt><tt> </tt><tt>greeter-session=unity-greeter</tt><tt> </tt><tt># for your login screen, e.g. LightDM (Ubuntu 11.10) or GDM (11.04 or earlier)</tt><tt> </tt><tt>display-setup-script=/usr/share/setdualmonitor.sh</tt><tt> </tt><tt># for your desktop session</tt><tt> </tt><tt>session-setup-script=/usr/share/setdualmonitor.sh</tt> This doesn't works. In both monitors I have the same output, and the desktop is not extended. How can I make the desktop extended at startup? best regards <div class="moz-signature">-- <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"> <meta name="generator" content="Bluefish 2.0.1"> <a href="http://www.powersoft-audio.com"><img src="cid:part1.00000204.00000603@powersoft.it" align="bottom" border="0"></a> Massimiliano Cialdi | Senior engineer email: <a href="mailto:massimiliano.cialdi@powersoft.it">massimiliano.cialdi@powersoft.it</a> HQ Italy: Via E.
