[Bug 2122494] [NEW] Fingerprint reader gets randomly dissabled

 

Public bug reported:

I own the DELL 16" 4650 which is one of Canonical's supported laptops.
Came preinstalled with Ubuntu.

The fingerprint reader does not work as expected. After sleeps, reboots,
or updates (or whatever else triggers it, I don't know), the fingerprint
reading gets disabled. I have to re-scan my finger, it tells me that
this finger reading already exists, then I redo the scanning again, and
then it takes it in.

But after a couple of sleeps, or reboots, usually multiple times a day,
the same thing happens again, it gets disabled all by itself. The
frprint command line utility also says that no finger has been indexed
in its db (while it has, a lot of times so far).

I have set it up both via gnome's fingerprint ui, and via the pam-auth-
whatever terminal utility.

The same bug happens on CachyOS btw, installed in parallel on the same
computer, not just on ubuntu.

For a Canonical-authorized laptop, both the touchpad and the fingerprint
experience sucks. In fact, I bought this laptop specifically because you
say on your website that these are authorized laptops.

More info about my exact hardware via ubuntu-apport can be found on my
touchpad bug report: bug #2122154

Another issue is that the fingerprint reading on gdm during login does
NOT unlock the gnome keyring, so when launching Chrome/chromium it asks
for a password. Super annoying.
