How To Require a Username at Login

I've always kind of liked the extra security that came with having to enter your username as well as your password at login. It also, I find, looks better.

Here's how to do it.

1. Open the following file in a text editor...

/etc/lightdm/lightdm.conf

2. Simply Add the following lines...  

greeter-show-manual-login = true 
greeter-hide-users = true 
allow-guest = false

3. Save, restart and see the effects!

Disable Unnecessary Startup Applications

A simple one, more of a reminder than an instructional.

1. Open Startup Applications from the Unity dashboard.

2. Select the applications you no longer want to run and select Remove.

3. You can also use Boot Up Manager to disable unnecessary services and applications by putting

sudo apt-get install bum

into the terminal.
