All hardware components of MI Pro have Linux driver support (including fingerprint), which is quite rare.

During installation and usage, I encountered some minor issues, which I’ll point out here:

  1. Refer to Arch Wiki to install Fingerprint GUI
  2. After installation, found that Fingerprint GUI only works with root privileges
  3. Solution as follows (reference github issues)

Steps:

  1. Add the following to /etc/udev/rules.d/elan-fprint.rules:
ATTR{idVendor}=="04f3", ATTR{idProduct}=="0c1a", GROUP="plugdev"
  1. Run command:
udevadm trigger

PS: Personal experience proves that the fingerprint driver works almost perfectly. However, Fingerprint GUI’s recognition algorithm has an unacceptably low success rate, resulting in very poor user experience. 🙁
