Disabling Services in Ubuntu

It's easy to disable startup items in Ubuntu (System -> Preferences ->
Startup Applications), but disabling services can be a tiny bit harder.
You'll first want to get a list of all services, which I accomplished by
opening a terminal and typing:

ls /etc/init.d

Once you've Google'd and found which one(s) you'd like to remove, use
the update-rc.d to disable the scripts across all run-levels. Here's
are the commands I issued to disable the few services I didn't need for
my laptop:

sudo update-rc.d speech-dispatcher disable
sudo update-rc.d pcmciautils disable
sudo update-rc.d cups disable
sudo update-rc.d bluetooth disable
