  • You don't want to have a root account in the log in screen it's a bad habit. I can't see any reason why you would even want this...

You can do this by editing /etc/lightdm/lightdm.conf The default contents are just:

[SeatDefaults]
greeter-session=unity-greeter
user-session=ubuntu

And you can just add:

greeter-hide-users=true

Now logout and you'll see that there is no list of users in the login window.

so you can just write root as username...

If you want to return to old lightdm window that list all users just open /etc/lightdm/lightdm.conf file and remove the added line greeter-hide-users=true

Here is a community wiki. Often many users advice you not to use Ubuntu this way. You have sudo anyway which elevates the privileges to root for a single command using your account password.

But, if you have a good reason to be root you can do that as well in Ubuntu.

Below are some useful links:

Using Root as log in is not good, anyway if want it for some file management purpose, type "sudo nautilus" or "gksudo nautilus" whichever works in terminal and you can have your login as root.
