This question documents how we used to inflict the mandatory login banners required on our Linux machines at work. Unfortunately, this procedure is no longer effective with Gnome 3 in Fedora 15, 16 or 17. Gnome 3 seems to ignore the banner_message fields in gconf-editor.

Does Gnome 3 provide an equivalent procedure that allows us to present a warning message to users prior to login?


For the people still wondering how to implement a banner at login time I did this:

For Fedora

  • Create a file 20-login in /etc/dconf/db/local.d/: touch /etc/dconf/db/local.d/20-login
  • Put the following configuration in that file

    [org/gnome/login-screen] banner-message-enable=true banner-message-text='My warning banner!'

  • Delete /etc/dconf/db/local: rm -f /etc/dconf/db/local

  • Update dconf: dconf update

For Ubuntu

Uncomment the following lines in /etc/gdm3/greeter.dconf-defaults and edit the banner-message-text

  • [org/gnome/login-screen]
  • banner-message-enable=true
  • banner-message-text='Welcome!'

Then restart gdm systemctl restart gdm
