Try using sysv-rc-conf

sudo apt-get install sysv-rc-conf


and to start managing the services, execute

sudo sysv-rc-conf


Which will bring up interactive window like this



You can further navigate through pages using Ctrl+n for next page and Ctrl+p for previous page .You can enable and disable services by selecting SPACE on desired runlevels.

Another alternate would be  Jobs-Admin by installing through 

sudo apt-get install jobs-admin


Which also provides GUI like this 



For showing more jobs , you have to tick the Show Protected Jobs from its menu.

And third option would be chkconfig,

sudo apt-get install chkconfig


It can be used via CLI chkconfig, showing list of On/Off jobs.
Also we can view system services using chkconfig –list

Services can be turned on using

chkconfig &lt;service&gt; on


Services can be turned off using

chkconfig &lt;service&gt; off


And we can even add our own service, using a proper init script with proper headings.

chkconfig --add &lt;service&gt;


And another option can be referred here update-rc.d , explained briefly here. 

Note that for Ubuntu Server 12.04, update-rc.d is used instead of chkconfig.

How to enable or disable services?
I'd like to remove the post title from my static frontpage. Just that page.
I've created a child theme from a free Press75 theme. So I'd like to make this change in my child theme's function.php.

I used this code but it removes the title from all pages, posts and my navigation:

add_filter( 'the_title', 'remove_page_title' );

function remove_page_title() {
    if(is_page('138')) {
    }
    return '';
}


I thought it would just remove the title from the page with ID 138.
What am I doing wrong?

Thanks!
