If you are the only user on your Ubuntu system (or if you have a default user on a Ubuntu system that should always be the user logged in) then you might want to consider setting up auto login. What auto login does is, upon boot (or restarting X Windows), the system will automatically login to that particular user.
This way the user does not have to interact with the log in prompt. The one major downfall to this is that no password has to be given in order for your user to be logged in. This can be a security issue. So if you are concerned with security, this is not for you.
If, however, security is not an issue with a particular user, than auto login is a simple way to make Ubuntu even more user-friendly than it already is. And fortunately, auto login is simple to set up. In this tutorial you will learn how to set up auto login as well as tweak your log in screen.
The tool used to configure auto login is found in the Administration menu and is called "Login Window Preferences". When you go to launch this tool you will be required to enter your sudo password. When the window launches you will see six tabs:
The tab used to set up auto login is the Security tab. Click on that to see the settings available (see Figure 1 - Click to enlarge).
To enable auto login you simply have to follow these steps:
It's that simple. Now of course there is much more that can be done in this tab of the preferences window. So why not take advantage while you have it open?
If you want to be able to log on as the system administrator you can do so here. First you need to check the check box labeled "Allow local system administrator login". There is one catch. Remember that Ubuntu does not have, by default, a root user password. Because of this, even if you have this feature enabled, the administrator will not be able to log in. In order for this to work you have to give the root user a password. Understand the root user was not given a password in Ubuntu for a reason...simplicity. But if you would prefer to have an administrative user (and bypass having to use sudo) you can give the root user a password by following these steps:
Now your local administrator can log in. A word of warning: I don't recommend loggin in as root. There may be times when it seems necessary, but before you do exhaust other possibilities first. Bad things can happen when you log in as root.
Custom welcome message
When your login screen appears there is a welcome message next to the logo in the greeter. You can personalize this greeting in the Local tab of the preferences window. Click on this tab and look at the bottom of the window where you will see the "Welcome Message' section. By default the message is simply "Welcome". To change this click the check box for "Custom" and then enter the greeting you want to use. Once you are done click close.
Enabling auto login, when used in trusted locations, can be a time saver as well as a way to make your Linux installation more user-friendly. For some users, having to log in to their computer is a real hassel. Help those users out by setting up auto login.
