# Display a text banner on the login screen

You can display extra text on the login screen, such as who to contact for support, by setting the org.gnome.login-screen.banner-message-enable and org.gnome.login-screen.banner-message-text GSettings keys.

# Display a text banner on the login screen:

Create a gdm keyfile for machine-wide settings in /etc/dconf/db/gdm.d/01-banner-message:

[org/gnome/login-screen] banner-message-enable=true banner-message-text='Type the banner message here.'

There is no character limit for the banner message. gnome-shell autodetects longer stretches of text and enters two column mode.

The banner message cannot be read from an external file.
