Dell is adding new code in Linux kernel that will enable you to disable newer Dell system8217s webcam and microphone with keyboard shortcuts. Why Because privacy.
Privacy is no longer a luxury. It has become the basic necessity.
Privacy-oriented niche devices like Librem notebook series offer hardware kill switches to block webcam microphone Bluetooth and Wi-Fi.
Dell will also be providing hardware kill switches in 2021 in the form of keyboard combination. It is implementing kill switch at kernel level and thus allowing you to disable webcam and microphone with keyboard shortcut.
In a patch to Linux kernel Dell disclosed its privacy driver that protects users privacy of audio and camera from hardware level. Once the audio or camera privacy mode enabled any applications will not get any audio or video stream.
With CtrlF4 hotkey audio privacy mode will be enabled and camera mute hotkey is CtrlF9.
