    Smile Unity "login" or "welcome" screen. 12.04

    For security reasons, I do not wish all usernames to be displayed on system boot up.
    I only wish the old, familiar field "user" with a blank field.
    And the old, familiar (also blank) field "password".

    In previous versions of Linux and other OS's, this option has always been available.
    I'm sure there is a simple solution.

    Thanks in advance for your answers.

    Re: Unity "login" or "welcome" screen. 12.04

    Ubuntu's login manager does this by default, I don't know of any comprehensive lightdm theme collections so I'd recommend switching to gdm or mdm, this link will help you with mdm, http://www.webupd8.org/2012/05/insta...er-mdm-in.html its written for Ubuntu 12.04 you don't have listed which version your using but the method shoudln't differ drastically for 12.10, gdm is the official repos but I'm not familiar with its newest version and I don't know how much it offers in the way of customisation

    Talking Re: Unity "login" or "welcome" screen. 12.04

    Captain mark (or anyone who can help)

    I've successfully installed GDM on my 12.04 (Desktop, i386), and it does give me an "other" feature.
    That helped. what I need to know now?
    How do I customize it?
    in 11.04, there was an app called "login screen" which had a check box
    "show list of users"
    This is what I DON'T want to see, so I'd always uncheck the check box.

    Anyone, got any ideas, perhaps there is a command line alternative...that's fine. Please advise.

    I can't remember if this tool has a setting for that, but you might want to give it a try:

    There was no need to switch display managers, this can be done using the default LightDM.
    Just edit the file /etc/lightdm/lightdm.conf and add the line:
    Code:
    greeter-hide-users = true

    Cool, nice little hack, run
    Code:
    sudo dpkg-reconfigure lightdm
    to select lightdm back as the login manager for this

    This is good to know. I already installed gdm. I'd prefer to use LightDM like you say. Is there a way to swith Display managers w/o uninstalling gdm?
    What happens if I just uninstall gdm? I'd rather not try, it has given me some extra stuff.

    One MORE question.
    I'm using 12.04 desktop. which file do I VIM and what parameters do I change too..
    boot w/o any gui front end? ie just a login from the bash shell?
    I've done this with 11.04, installing the server from scratch. But I don't want to go through that again and I like 12.04.
    also what is the command to start the gui? it used to be "startx"

    Thanks everyone.

    Just do what CaptainMark said a couple of posts up.
    Code:
    sudo dpkg-reconfigure lightdm
    I'm using 12.04 desktop. which file do I VIM and what parameters do I change too..
    boot w/o any gui front end? ie just a login from the bash shell?
    No need to edit any existing files, just run the following to create the lightdm.override file:
    Code:
    echo  "manual" | sudo tee -a /etc/init/lightdm.override
    also what is the command to start the gui? it used to be "startx"
    It still is.
