After “Apply” every thing works that I want.
But this configuration works until next PC boot.
After PC reboot, The configuration (Position) has changed to “Clone of”.
More info may help here. Which version of openSUSE are you using? (I’m just wary of providing advice for openSUSE 11.2 related issues, as the graphical version of sax2 has apparently been removed). Are you using radeon or fglrx driver?
Did you applied the settings as user or su?
Try configuring it as su. like,
open a console/terminal or use the run command and type kdesu systemsettings, enter your root password. I have not use it on my machine so I am just guessing here.
