Create an user account with password. 2. Login in the new account using the XFCE desktop environment. 3. Lock the screen. 4. Hit the Ctrl+Alt+F7 key combination. EXPECTED BEHAVIOUR: - The user session to be unavailable due to no password being entered. REAL BEHAVIOUR: - The session is accessible without entering its password, due to the VT8 being bypassed to the original VT using the Ctrl+Alt+F7 key combination.
