I have a 6-month-old Lenovo T14s Gen 3 (Intel) laptop, with Ubuntu 22.04.2. It died suddenly, so Lenovo replaced the motherboard. Now the fingerprint reader won't allow me to record prints. I have done a "factory reset" of the fingerprint reader in the BIOS. I've also (before that) tried deleting all records using fprintd.
But now/still, when I run "fprintd-enroll", I get:
Using device /net/reactivated/Fprint/Device/0
Enrolling right-index-finger finger.
and then it waits. I touch the fingerprint reader and immediately it aborts with:
Enroll result: enroll-disconnected
Same if I specify a different finger.
sudo lshw shows this, but I can't see a fingerprint reader
*-input:7
product: Power Button
physical id: 9
logical name: input2
logical name: /dev/input/event2
capabilities: platform
I can't see anything fingerprint-related in ls -l /dev either.
In sudo journalctl -b 0 I found this, which I think are simply where authentication is choosing not to use it in favor of a typed password(??):
Jul 06 09:14:39 mylaptop gdm-fingerprint][19449]: gkr-pam: no password is available for user
and these:

By the way, every second, a message like this is going to the journal:
Jul 06 11:04:31 mylaptop kernel: i2c_designware i2c_designware.1: controller timed out
If there's a hardware issue, Lenovo would be willing to help/fix it. But it seems to recognize that I've touched it, so I think everything must be connected. How can I get it working?
