# Lock the screen when user is idle

You can make the screen lock automatically whenever a user is idle for some amount of time. This is useful if your users may leave their computers unattended in public or unsecure locations.

# Enable automatic screen lock

Create the key file /etc/dconf/db/local.d/00-screensaver to provide information for the local database.

# /etc/dconf/db/local.d/00-screensaver

# Specify the dconf path [org/gnome/desktop/session]

# Number of seconds of inactivity before the screen goes blank idle-delay=uint32 180

# Specify the dconf path [org/gnome/desktop/screensaver]

# Lock the screen after the screen is blank lock-enabled=true

# Number of seconds after the screen is blank before locking the screen lock-delay=uint32 0

You must include the `uint32` along with the integer key values as shown.

To prevent the user from overriding these settings, create the file /etc/dconf/db/local.d/locks/screensaver with the following content:

# /etc/dconf/db/local.db/locks/screensaver

# Lock desktop screensaver settings /org/gnome/desktop/session/idle-delay /org/gnome/desktop/screensaver/lock-enabled /org/gnome/desktop/screensaver/lock-delay
