Configurar o peche da sesión automático

User sessions that have been idle for a specific period of time can be ended automatically. You can set different behaviour based on whether the machine is running from a battery or from mains power by setting the corresponding dconf key, then locking it.

Keep in mind that users can potentially lose unsaved data if an idle session is automatically ended.

Set automatic logout for a mains powered machine

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

    /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. Create a local database for machine-wide settings in /etc/dconf/db/local.d/00-autologout:

    [org/gnome/settings-daemon/plugins/power]
# Set the timeout to 900 seconds when on mains power
sleep-inactive-ac-timeout=900
# Set action after timeout to be logout when on mains power
sleep-inactive-ac-type='logout'

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

    # Lock automatic logout settings
/org/gnome/settings-daemon/plugins/power/sleep-inactive-ac-timeout
/org/gnome/settings-daemon/plugins/power/sleep-inactive-ac-type

  5. Actualizar a base de datos do sistema:

    # dconf update

  6. Os usuarios deben pechar a sesión e iniciala de novo para que a configuración a nivel de sistema se aplique.
