The rise in demand for biometric security has brought USB fingerprint readers into the homes of many Linux users and PC enthusiasts. One of the more affordable and accessible devices is the , which uses the Chipsailing CS9711 capacitive sensor chip . However, this reader’s popularity has grown not because of official support but because of a dedicated open source community that has created drivers for it.
sudo systemctl restart polkit
Check which library fprintd is loading:
sudo cp /usr/local/lib64/libfprint-2.so.2 /usr/local/lib/ echo "/usr/local/lib" | sudo tee /etc/ld.so.conf.d/fprint.conf sudo ldconfig
Open a terminal and run:
lsusb
Create a custom PAM configuration for Polkit: cs9711 fingerprint driver
Using the CS9711 driver to enable is significantly more secure than a standard password. Since the biometric data is usually stored in a "secure island" on the chip or encrypted within the Windows TPM (Trusted Platform Module), your actual fingerprint image never leaves the device.
