//Add the support for your cpt in the Widget Activity of the Admin Dashboard
if ( is_admin() ) {
	add_filter( 'dashboard_recent_posts_query_args', 'add_page_to_dashboard_activity' );

	function add_page_to_dashboard_activity( $query_args ) {
		if ( is_array( $query_args[ 'post_type' ] ) ) {
			//Set yout post type
			$query_args[ 'post_type' ][] = 'page';
		} else {
			$temp = array( $query_args[ 'post_type' ], 'page' );
			$query_args[ 'post_type' ] = $temp;

	}

}

@MajorRedbeard just $query_args['order'] = 'DESC'; $query_args['orderby'] = 'date';. If you want to update how many posts are displayed update$query_args['posts_per_page'] = $int; It's that easy. The dashboard_recent_posts_query_args hook accepts all of the same arguments as WP_Query.

Thanks.. it works for just one kind of custom post type...
What if I have two diferent custom post types?

@tallieven try that way:

if ( is_admin() ) {
	add_filter( 'dashboard_recent_posts_query_args', 'add_page_to_dashboard_activity' );
	function add_page_to_dashboard_activity( $query ) {
		// Return all post types
		$post_types = get_post_types();
		// Return post types of your choice
		// $post_types = ['post', 'foo', 'bar'];
		if ( is_array( $query['post_type'] ) ) {
			$query['post_type'] = $post_types;
		} else {
			$temp = $post_types;
			$query['post_type'] = $temp;
		}
		return $query;
	}
}

Is it possible to add post type name and author next to post name ? and increase the number of last posts (more than 5) ?
Thanks !

Well, the default dashboard_recent_posts_query_args accepts all WP_query arguments, like posts_per_page to increase the number of posts see here. But, this function only return date and title.

The easy way to display other fields is creating a custom dashboard widget, like this, and add the loop with all fields you wish (you can use the core function loop), and implement post type and author fields.

Thank you, that's exactly what i need !
