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

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.

    Instead of logging out, you can also use "Switch User". –  Aug 15 '10 at 16:41

    Does not work with 11.10 or later as they use LightDM instead of GDM. – James Jun 10 '12 at 16:03
  • Does not work with Ubuntu 17.10 where GDM is default again. A working example can be found on https://didrocks.fr/2017/09/11/ubuntu-gnome-shell-in-artful-day-11/ – user17254 Nov 08 '17 at 22:17

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.

    It doesn't allow you to change any fonts, font-hinting, pointers, selected-item colors or icons. Just the wallpaper and the logo . – daithib8 May 05 '11 at 18:10

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.

    What? Can I change any options at all? Who says? NOOOOOOOO!!!!! – WindowsEscapist May 22 '12 at 14:44
  • You cannot change any thene or any option related to its looks...What is offered is what you will have to accept..You may consider reinstalling lightdm – Nirmik May 22 '12 at 14:46
  • Yeah... I can't, because I can't log in from LightDM (it's borked in 12.04 x64). Well, thanks. ;( (But where is this info from?) (I would still like to know.) – WindowsEscapist May 22 '12 at 14:51
  • Hmmm... thanks for the info. Interesting, my GDM looks different than that, more square and such. I just configured gdm from terminal login, and didn't install anything. Darn. – WindowsEscapist May 22 '12 at 15:02

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

  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.
