The important step is to exit yast2. For more info see https://bugzilla.novell.com/show_bug.cgi?id=116483

Keyboard

If you want to use a german dvorak keyboard layout, you have to change /etc/X11/xkb/symbols/de, the "dvorak" section must contain

include "level3(ralt_switch)"

as discussed at https://bugs.freedesktop.org/show_bug.cgi?id=2681

With keyboard switcher

If you are using the KDE keyboard switcher, you have to make sure it draws the new settings. First, try if your layout works as you expect it by issueing

setxkbmap -model pc105 -layout de -variant dvorak

then, start kcontrol->Regional & Accessibility->keyboard layout. Install the "basic" variant, click on "apply". Then, chose the "dvorak" variant and click on apply again. Test that your keyboard layout works as you expect it.
