How to change the GDM theme
To change the GDM (lock/login screen) theme, you need to replace the system's default GNOME Shell theme.
⚠️ Cautions ⚠️
- If the replacement fails, your desktop environment will not work properly. So please be careful if doing this.
- When applying this, other third-party GNOME Shell themes would look broken until you restore to the original theme.
- If GNOME Shell has been updated and restored to the original theme, you will need to install this again.
Note: On Arch Linux, you can automatically reinstall the GDM theme by creating a hook file. For example, if you use gruvbox-material-dark-materia-compact as your GDM theme, put this file in the
/usr/share/libalpm/hooks/
directory.
Requirements
glib-compile-resources
— The package name depends on the distro.glib2
(Arch Linux)glib2-devel
(Fedora, openSUSE, etc.)libglib2.0-dev-bin
(Debian, Ubuntu, etc.)
libxml2-utils
— Ubuntu users only.
Installation
- Back up the original theme file(s) first. If you are already using a custom GDM theme, skip this:
sudo cp -av /usr/share/gnome-shell/gnome-shell-theme.gresource{,~}
# For Ubuntu 17.10 or 18.04, you also need the following:
sudo cp -av /usr/share/gnome-shell/theme/ubuntu.css{,~}
# For Ubuntu 18.10, you also need the following:
sudo cp -av /usr/share/gnome-shell/theme/Yaru/gnome-shell.css{,~}
- Select a GTK theme to decide which variant to install.
- Replace the default theme file(s):
GTK_THEME=$(gsettings get org.gnome.desktop.interface gtk-theme | sed "s/'//g")
cd /usr/share/themes/${GTK_THEME}/gnome-shell
sudo glib-compile-resources --target=/usr/share/gnome-shell/gnome-shell-theme.gresource gnome-shell-theme.gresource.xml
# For Ubuntu 17.10 or 18.04, you also need the following:
sudo cp -av gnome-shell.css /usr/share/gnome-shell/theme/ubuntu.css
# For Ubuntu 18.10, you also need the following:
sudo cp -av gnome-shell.css /usr/share/gnome-shell/theme/Yaru/gnome-shell.css
- Reload the theme. If you are running GNOME Shell, press Alt + F2 then type
rt
.
Uninstallation

sudo mv -v /usr/share/gnome-shell/theme/ubuntu.css{~,}
# For Ubuntu 18.10, you also need the following:
sudo mv -v /usr/share/gnome-shell/theme/Yaru/gnome-shell.css{~,}
