Lock screen notifications enables you to see and dismiss all system notifications right from the lock screen without needing to unlock your system. It notifies by displaying the pop-up messages on the top of the screen. Some users find it convenient as it notifies them at first glance without unlocking their system. But doing so can put your system privacy and security at risk as anyone having access to your system can see it. If you think your lock screen might contain some sensitive information, you should consider disabling it. That is why in this article, we are going to explain how to disable notifications on a Debian lock screen. To achieve this, we will use two different ways. However, you can use any one of them.
