I still see the issue with 20.04 After a reboot, I get the 'swipe finger to login' message. I swipe, it tries to login and immediately logouts. I then have to wait for the timeout to enter the password, I login and logout, and the fingerprint now works without any issue.
Message on syslog is the same as above mentioned fprintd[1154]: Device responded with error: 789 fprintd[1154]: Ignoring device due to initialization error: The driver encountered a protocol error with the device.
