Fix Recommendation

Configure AlmaLinux OS 9 to initiate a screensaver after a 10-minute period of inactivity for graphical user interfaces.

Create a database to contain the systemwide screensaver settings (if it does not already exist) with the following command:

$ touch /etc/dconf/db/local.d/00-screensaver

Edit /etc/dconf/db/local.d/00-screensaver and add or update the following lines:

[org/gnome/desktop/session]
# Set the lock time out to 600 seconds before the session is considered idle
idle-delay=uint32 600

Update the system databases:

$ dconf update

Check Contents

Note: This requirement assumes the use of the AlmaLinux OS 9 default graphical user interface, the GNOME desktop environment. If the system does not have any graphical user interface installed, this requirement is Not Applicable.

Verify AlmaLinux OS 9 initiates a session lock after a 10-minute period of inactivity for graphical user interfaces with the following command:

$ gsettings get org.gnome.desktop.session idle-delay

uint32 600

If "idle-delay" is set to "0" or a value greater than "600", this is a finding.
