13.8. Locking Down User Logout and User Switching

Follow these steps to prevent the user from logging out.
  1. Create the /etc/dconf/profile/user profile which contains the following lines: 
    user-db:user
system-db:local
    local is the name of a dconf database.
  2. Create the directory /etc/dconf/db/local.d/ if it does not already exist.
  3. Create the key file /etc/dconf/db/local.d/00-logout to provide information for the local database: 
    [org/gnome/desktop/lockdown]
# Prevent the user from user switching
disable-log-out=true
  4. Override the user's setting and prevent the user from changing it in /etc/dconf/db/local.d/locks/lockdown: 
    # Lock this key to disable user logout
/org/gnome/desktop/lockdown/disable-log-out
  5. Update the system databases: 
    # dconf update
  6. Users must log out and back in again before the system-wide settings take effect.

Important

Users can evade the logout lockdown by switching to a different user, which can thwart system administrator's intentions. That is the reason why it is recommended to disable "user switching" as well to prevent this scenario from occurring.
