After some recent updates on my Arch Linux, I suddenly discovered that my fingerprint login is no longer working. I deleted my already-enrolled fingerprints and found that I wasn't able to enroll any fingerprint any more.
After some digging around, I compiled libfprint with --enable-debug-log and found that whenever I do a fprint-enroll it hangs, and after some swipes it results in a core cump of fprintd.
It is also worth mentioning that the sensor used to blink during enrollment, but now it only flash a green light once at the start of enrollment.
I have installed fprintd from offical repo and libfprintd-git from AUR two years before, and they worked well for me until recently.
