How to Disable Startup Programs on Your Computer

You might not even realize it, but when you first log onto your PC, dozens of programs and services are starting that you most likely don't need. Some rear their ugly heads in the system tray (that little collection of icons next to the clock in Windows), but others run quietly in the background with you none the wiser.
Now, don't get scared, these instructions will take you to corners of your operating system (OS) you may not have seen before, but follow our instructions below and you should notice slightly quicker performance and potentially much faster boot times. Every Linux distribution is slightly different, so check the support forums for your particular flavor if this doesn't work for you.
Linux:
Under a standard Ubuntu desktop go to the System menu on the top bar.
Go to Administration, then Services.
You can safely uncheck Braille display management.If you use a webmail service like Gmail instead of a desktop app you can uncheck Mail Agent, and, unless you have and need your Bluetooth device, you can uncheck Bluetooth Device Management.
To disable start up programs drop down the System menu again.Go to Preferences and open Sessions.

Here uncheck things you don't need or use, like Bluetooth, Evolution Alarm Notifier, and Remote Desktop. Make sure not to uncheck things like Window Manager.
