Description:
GNOME Desktop Manager can make the screen lock automatically whenever the user is idle for some amount of time.
Rationale:
Setting a lock-out value reduces the window of opportunity for unauthorized user access to another user's session that has been left unattended.
Fix:
Edit or create the file /etc/dconf/db/local.d/00-screensaver and edit or add the following:
[org/gnome/desktop/session]
idle-delay=uint32 900
And run the following command to update dconf database:
# dconf update
Parameter:
[900 secs, 5 secs]
Technical Mechanism:
Edit or create the file /etc/dconf/db/local.d/00-screensaver and edit or add the following:
[org/gnome/desktop/session]
idle-delay=uint32 900
[org/gnome/desktop/screensaver]
lock-delay=uint32 5
And run the following command to update dconf database:
# dconf update
