Hi all Trying to solve my problem with ubuntu (gnome version), it seems that it can be done by launching Xrandr early in Xsession.
What I did was to create a file called "45custom_xrandr-settings" what is in this file: EXTERNAL_OUTPUT="VGA1" INTERNAL_OUTPUT="DP1" xrandr --output $INTERNAL_OUTPUT --auto --primary --output $EXTERNAL_OUTPUT --off Simply copy it to the folder "/etc/X11/Xsession.d/" I don't know why but after that you can connect an external screen and activate it using System>preference>Monitors without crash. I have used the "--primary" argument so that gnome panels stay on the laptop screen in extended mode. I hope it will help someone.
