Had a lot of trouble getting the fingerprint sensor to work on my Lenovo Yoga 9 with Ubuntu 24.04.3 LTS. This guide shows how to get the Goodix 27c6:650c fingerprint sensor working on Ubuntu 24.04 (or derivatives) by compiling libfprint v1.94.9 and fprintd from source.

Note: This sensor is officially unsupported in Ubuntu’s repositories, so a compiled version of libfprint with Goodix support is required.
