SUMMARY STEPS TO REPRODUCE / OBSERVED RESULT Can't give precise information on that. All I can say is: I managed to install the nvidia-drivers 430 on my Lenovo P52 with an external Thunderbolt screen (ASUS MB16AC) connected. When I rebooted, the login dialog on the external screen was preselected (not the laptop screen, which is the main screen). When I now enter the password in the password dialog on the main screen, *the entered password is not censored*! It's visible in cleartext. EXPECTED RESULT Password should be censored!
