FYI people!

I had the problem of wanting an extended display on my new LXDE box, (not a dual clone), found the correct command, but couldn't make it permanent.

The correct command was:

xrandr --output VGA-0 --right-of DVI-0

Found some pointers here:
but all these methods seemed too hard/not the right way to do it.

I eventually found this: http://www.sudo-juice.com/change-lxd...buntu-lubuntu/

that worked a treat, but used gedit instead, so from the command line:

sudo gedit /etc/xdg/lxsession/LXDE/autostart

then in gedit added the line at the end of autostart file with an @ symbol at the start:

@xrandr --output VGA-0 --right-of DVI-0

Hope that helps and thank you to sudo-juice.


PS Note the double "-" in the xrandr command "--" (didn't show up too clearly on my screen).
