How can I change the login screen theme in GDM?

Question

How can I change the Login screen theme? Is there a graphical way or no?

Answer 1

Use this command in the terminal:

sudo cp /usr/share/applications/gnome-appearance-properties.desktop /usr/share/gdm/autostart/LoginWindow

Logout, and you will be prompted with the Appearance window. change the theme as you change it for the desktop, and login back, and type this command:

sudo rm /usr/share/gdm/autostart/LoginWindow/gnome-appearance-properties.desktop

That's it.

Answer 2

This depends on what you want to do with the login screen. You can configure some basic options in the Login Screen Settings app (System/Administration/Login Screen) - whether a user should be automatically logged in, the default session etc.

However to change the login screen more graphically Ubuntu Tweak can be used to change the background, logo etc.

Answer 3

U can use GDMtweak to change theme and Icon. see the link http://www.webupd8.org/2011/05/change-gdm-theme-background-in-ubuntu.html

Answer 4

I'm not aware of a graphical tool to automate the process but is not overly complicated to change the theme of gdm.

Take a look at Gnome-Look GDM, most of the themes there come with good instructions on how to install them.

Answer 5

Theme Support for GDM has been terminated since UBUNTU 9.Sorry..!!

Answer 6

There is a graphical tool for this. It's called GDM2Setup. You can get it from this PPA: https://launchpad.net/gdm2setup

Answer 7

1. Copy the image you want to use into the /usr/share/gnome-shell/theme folder.

2. Run

   sudo -H gedit /usr/share/gnome-shell/theme/gnome-shell.css
   

3. Search for the following section

   #lockDialogGroup { 
   
   background: #2e3436 url(noise-texture.png); 
   
   background-repeat: no-repeat;
   

4. Change the name of the image to your image and set background to repeat or no-repeat.

5. Save the file.

6. Logout and your new background is there.

This works for Ubuntu GNOME, for other flavours it might not work.
