How to Install a GDM Login Theme

출처 : http://forums.fedoraforum.org/showthread.php?t=113539

1) Find a theme you like.

1a) Go to http://www.gnome-look.org.
1b) Click on "GDM Themes" on the menu to the left.
1c) Click on the "Highest Rated" tab, near the top of the content area.
1d) Select a theme that you like. For this example, we will be using Avio-GDM, which is a theme that I like so much that three Fedora Core 5 boxes under my control are using it.

2) Download the theme

2a) On the theme's page, click the "Download" link.
2b) Save the file -- in my case, 37395-Avio-GDM.tar.gz -- to your Desktop.

3) Unpack the theme.

3a) Right-click on the *.tar.gz file that you downloaded.
3b) Select "Extract Here" from the menu.
3c) A folder with the contents of the *.tar.gz file now exists on your Desktop. In my case, the folder is called "Avio-GDM".

4) Move the folder to your themes directory.

4a) Open a terminal (Applications > Accessories > Terminal).
4c) Become root: Run "su", and enter the root password when prompted.
4d) Go to where the theme is presently: "cd Desktop".
4e) Move the folder to the GDM theme directory: "mv Avio-GDM /usr/share/gdm/themes/". Obviously, you will substitute the folder that contains your theme for "Avio-GDM".

5) Select your theme to be the one used.

5a) Run System > Administration > Login Screen. Enter your root password if you are prompted for it.
5b) Click on the radio button (the little circle) next to the theme you want to use.

6) Configure the face browser

These are the user account buttons that appear that can be clicked, similar to Microsoft Windows XP Home Edition.
6a) Go to the Users tab of the Login Window Preferences window.
6b) Click the Add button under the Include section (on the left).
6c) Type the name of the user account you wish to have listed on the login screen.
6d) Repeat steps 6b and 6c until all human accounts are added (or at least the ones you want to be listed).

7) See the results.

7a) Close all open windows.
7b) Log Out (System > Log Out).

8) Enjoy the results.
