Desactivar a sesión de usuarios e a conmutación de usuarios

Preventing the user from logging out is useful for special kind of GNOME deployments (unmanned kiosks, public internet access terminals, and so on).

Users can evade the logout lockdown by switching to a different user. That is the reason why it is recommended to also disable user switching when configuring the system.

Desactivar a sesión de usuarios e a conmutación de usuarios

    /etc/dconf/profile/user

    user-db:user
system-db:local

    local é o nome dunha base de datos dconf.

  2. Create the directory /etc/dconf/db/local.d/ if it does not already exist.

  3. Cree o ficheiro de chaves /etc/dconf/db/local.d/00-logout para fornecer información sobre a base de datos local:

    [org/gnome/desktop/lockdown]
# Prevent the user from logging out
disable-log-out=true

# Prevent the user from user switching
disable-user-switching=true

  4. Override the user's setting and prevent the user from changing it in /etc/dconf/db/local.d/locks/lockdown:

    # Lock user logout
/org/gnome/desktop/lockdown/disable-log-out

# Lock user switching
/org/gnome/desktop/lockdown/disable-user-switching
