Mostrar un anuncio de texto na pantalla de inicio de sesión

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.

Mostrar un anuncio de texto na pantalla de inicio de sesión:

  1. Cree o perfíl gdm que contén as seguintes liñas:

    /etc/dconf/profile/gdm

    user-db:user
system-db:gdm
file-db:/usr/share/gdm/greeter-dconf-defaults

    gdm é o nome dunha base de datos dconf.

  2. 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='Escriba o mensaxe de anuncio aquí.'

  3. Actualizar a base de datos do sistema:

    # dconf update

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.
