How do i filter posts in Home page.

I want to display only some specified posts in the home page , instead of all posts.

I have the id of all the post that i want in the home page.

How do i do it with wp_query or query_post(); ?

By using the following code , i am getting the result but the gallery does not comes in the posts.
Have a look.

function exclude_category( $query ) {

	$ids=get_option("Fpost_list");
    if ( $query->is_home ) {
       	 $query->query_vars["post__in"]=$ids;
    }

    return $query;
}

add_filter( 'pre_get_posts', 'exclude_category' );

The above code works , but i cannot understand why the gallery doesnt shows up.

Any correction or suggestion would be wonderful..

Thank you.
