RHEL-10-700750 - RHEL 10 must automatically lock graphical user sessions after 15 minutes of inactivity.

Information

A session timeout lock is a temporary action taken when a user stops work and moves away from the immediate physical vicinity of the information system but does not log out because of the temporary nature of the absence. Rather than relying on the user to manually lock their operating system session prior to vacating the vicinity, the GNOME desktop can be configured to identify when a user's session has idled and take action to initiate a session lock.

Solution

Configure RHEL 10 to initiate a screensaver after a 15-minute period of inactivity for graphical user interfaces.

Note: The example below is using the database "local" for the system. If the system is using another database in "/etc/dconf/profile/user", the file should be created under the appropriate subdirectory.

Update the "/etc/dconf/db/local.d/00-screensaver" file to prevent nonprivileged users from modifying the screensaver idle-delay setting:

$ sudo vi /etc/dconf/db/local.d/00-screensaver

[org/gnome/desktop/session]
# Set the lock time out to 900 seconds before the session is considered idle
idle-delay=uint32 900

Update the system databases:

$ sudo dconf update
