Well, it's more of a design problem of X11. Under Wayland, the compositor could offer a Secure Attention Key like Ctrl-Alt-Del that reclaims input focus from a fullscreen application. As far as I'm aware, such facilities do not exist in X11. When an application grabs the keyboard, it's grabbing the entire keyboard.

- ratmice 7y agoYes, the problem is that X11's login/lock screen is secured by grabbing the keyboard and mouse, taking away input focus from the login screen in many cases will allow you to bypass it entirely.
- Crinus 7y agoSuch facilities actually do exist in Xorg, they are just disabled by default. But you can configure the server with a shortcut key to release input grab.
