not possible to enroll finger (Exception: Point is not on the curve)
rootsh0pf opened this issue · 1 comments
I'm running dualboot Windows and Ubuntu 20.10 on a Lenovo Thinkpad Yoga 370 which has a 138a:0097 fingerprint reader. I installed libfprint-2-tod-vfs0090 from your PPA and validity-sensors-tools from snap. I enrolled my finger in Windows and tried to enroll it also in Ubuntu but it does not work:
sudo validity-sensors-tools -t enroll
Found device <DEVICE ID 138a:0097 on Bus 001 Address 005>
Opening device 0x97
Traceback (most recent call last):

raise Exception('Point is not on the curve')
Exception: Point is not on the curve
fprintd-enroll also fails with no devices available
Does someone know, what the exception "Point is not on the curve" means?
