I guess you’re using T3 Blank template, right?
The ‘position-1’ is included in spotlight block which displays in a container. You can try to create a new block called slideshow, for example, add the associated php file in directory: root/templates/your_default_template/tpls/blocks/slideshow.php
and add this code inside this new file:
<?php
/**
* @package T3 Blank
* @copyright Copyright (C) 2005 - 2012 Open Source Matters, Inc. All rights reserved.
* @license GNU General Public License version 2 or later; see LICENSE.txt
*/
defined('_JEXEC') or die;
?>
<?php if ($this->countModules('slideshow')) : ?>
<!-- SLIDESHOW -->
<div class="slideshow hidden-xs <?php $this->_c('slideshow') ?>">
<jdoc:include type="modules" name="<?php $this->_p('slideshow') ?>" style="raw" />
</div>
<!-- //SLIDESHOW -->
<?php endif ?>
Of course, you will need to create a new position called slideshow
