Check Text (C-258025r958402_chk)

Verify RHEL 9 initiates a session lock for graphical user interfaces when the screensaver is activated with the following command: Note: This requirement assumes the use of the RHEL 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. $ gsettings get org.gnome.desktop.screensaver lock-delay uint32 5 If the "uint32" setting is not set to "5" or less, or is missing, this is a finding.

Fix Text (F-61690r926061_fix)

Configure RHEL 9 to initiate a session lock for graphical user interfaces when a screensaver is activated. Create a database to contain the system-wide screensaver settings (if it does not already exist) with the following command: Note: The example below is using the database "local" for the system, so if the system is using another database in "/etc/dconf/profile/user", the file should be created under the appropriate subdirectory. $ sudo touch /etc/dconf/db/local.d/00-screensaver [org/gnome/desktop/screensaver] lock-delay=uint32 5 The "uint32" must be included along with the integer key values as shown. Update the system databases: $ sudo dconf update
