The buzzert screen locker
This is a graphical screen locker for X11, for use in conjunction with XSecureLock. It uses PAM for authentication, so you can use it with your Yubikey/fingerprint scanner, etc. as well.
This project uses the Meson build system:
meson build ninja -C build
By building buzzlocker by itself, you'll end up with a binary called
This is meant to be used in conjunction with XSecureLock,
which does all the heavy-lifting with regards to properly locking an X session and ensuring other
windows cannot steal focus or cause the locker to disappear somehow. It also handles secure keyboard
input to make sure key events don't get delivered to applications in the background.
If you run
auth_buzzlocker by itself, you can preview what the screen locker looks
like in windowed-form. If you want to use buzzlocker as your screen locker with XSecureLock,
all you need to do is set the
XSECURELOCK_AUTH environment variable to point to
So you might want to do:
sudo ninja -C build install
If you want to make it permanent, edit
/etc/environment to include this line:
So every time you run
xsecurelock by itself, it will use buzzlocker as the GUI.
If you have multiple monitors, buzzlocker will appear only on whatever the primary monitor is (according
to XRandR). If you want to override this behavior, set the environment variable
to whichever monitor you wish to have buzzlocker appear on.
The original project is from buzzert, which I adapt for myself.
