Exemple

gsettings get org.gnome.desktop.a11y.keyboard stickykeys-enable
gsettings set org.gnome.desktop.a11y.keyboard stickykeys-enable false

Autre solution

/usr/share/gdm/dconf/99-local-settings

[org/gnome/settings-daemon/plugins/power]
sleep-inactive-ac-timeout=0

Voir http://askubuntu.com/questions/323776/gsettings-not-working-over-ssh

La commande gsettings ne fonctionne pas en SSH. Mais fonctionne en local dans un terminal graphique.

gsettings set org.gnome.desktop.lockdown disable-lock-screen true

Vérif

gsettings get org.gnome.desktop.lockdown disable-lock-screen

false

Cela n'a pas fonctionné. Cela est dû au fait que dbus n'est pas démarré dans le session SSH.

Préfixer votre commande par dbus-launch

dbus-launch gsettings set org.gnome.desktop.lockdown disable-lock-screen true

Dump

dconf dump /

Ou

gsettings list-recursively

Éditeur en mode texte :

• gsettings (libglib2.0-bin)
• dconf (dconf-cli)
• gconftool-2 (gconf2)

Éditeur en mode graphique :

• dconf-editor (dconf-editor)

Une partie de la conf est enregistrée ici :
~/.config/dconf/user

La preuve :

$ gsettings get org.gnome.desktop.lockdown disable-lock-screen
true
$ rm .config/dconf/user
$ gsettings get org.gnome.desktop.lockdown disable-lock-screen
false

/usr/share/glib-2.0/schemas/org.gnome.desktop.lockdown.gschema.xml

Autre : dconf update
