Display setting for two screens

Not sure if I’m doing right to post this on this thread but I’ve got an issue with my laptop screen extension. I have plugged a vga monitor to my laptop for a right display extension. The idea is to put the right extension on the vga monitor but don’t why the monitor is know my main screen and my laptop the extension. I have tried to change sides but the laptop is still the extension and not the main one as I want.

Is there a hard way to make this work?

When you type “xrandr” in a terminal, do you get a GUI helping you to configure this?

No, only some video settings info:

reads almost like a KDE4.4.3 bug ?

How about if you run the “KRandRTray” ?

Maybe I should give a bit more detail …

Type in a terminal: krandrtray
and then look for a small “monitor” icon in lower right corner. Right click on that and select “configure display”. Use that to configure things.

It works and shows up the display settings panel. What do you suggest to try?

When you select ‘configure display’, don’t you see controls there for both LCD and CRT1 ? If so, then set them up the way you want.

I’m able to change screens sides but my main plasma desktop keeps its position on the vga screen. It only changes the logic way I mean where to follow the screen extension. Can’t get my desktop on my laptop screen. :\
