I found that the gui interfaces didn't work and was eventually successful with the xrandr commands. 

Check out: 

Make sure that you are correctly defining your monitors (should be obvious from the output of the xrandr command). 

LVDS is the laptop monitor, VGA is the external.

Subject: Dual screen with KDE4 

Hello guys, 

I am using Jaunty at work and have a small laptop screen (14") to which I added a 17" screen. 
I have been trying to use 'Screen Resize & Rotate' to get my desktop on both screens, but it does not offer the option. 

It is worth also noting that: 
- I did not manage to do it using xrandr (yet) 
- it can be set up in two clicks on that other OS 

Anybody got any idea? 

Note also that adding: 
SubSection "Display" 
Virtual 2048 2048 
to the Section "Screen" broke X (with and without '"' around the 2048). 

All suggestions (other than running that other OS) welcome.
