I have found a couple Debian based distributions that have trouble turning off services at start up. To begin, services are background jobs that run on *nix systems. In compression to Windows they are what you can find by opening the task manager and finding the processes. You don't see the programs running because they are in the back ground. Most of these services are harmless but unnecessary. To stop a service in a Debian system type in the command.
sudo service servicename stop
sudo /etc/init.d/servicename stop
