@John and scribu:
i have no found a other solution as set the user_meta_dat for this. I have
write a small function to write the usermeta on activate the plugin. Please
-waht do you think about this?

register_activation_hook( __FILE__, array(&$this, 'install') );
        function install() {
            global $wpdb;

            $wp_users = $wpdb->get_results(


                "SELECT ID

                 FROM   $wpdb->users

                 ORDER  BY ID"


            $hidden_page = array();
            $hidden_post = array();
            $hidden_page = get_hidden_meta_boxes('page');
            $hidden_post = get_hidden_meta_boxes('post');
            array_push( $hidden_page, 'mygermancityfacts' );
            array_push( $hidden_post, 'mygermancityfacts' );
            foreach ( $wp_users as $user ) {
                $userID = (int) $user->ID;
                update_usermeta( $userID, 'metaboxhidden_page', $hidden_page
                update_usermeta( $userID, 'metaboxhidden_post', $hidden_post
