Bug Description

Binary package hint: thinkfinger-tools

This bug is related to 8.10. I was able to acquire and verify my fingerprint on a T61 laptop and each opportunity to use my fingerprint, it prompts for finger swipe, but does nothing. This worked fine in 8.04

On my system (thinkpad R60, Ubuntu 8.0 beta) authentication (at least sudo) via thinkfinger works BUT you have to press enter after swiping your finger (which makes the whole process rather annoying).

relevant lines in my /etc/pam.d/common-auth look like this:
auth sufficient pam_thinkfinger.so
auth [success=1 default=ignore] pam_unix.so try_first_pass nullok_secure

thx polpotak. This does seem to be the case. I can now use thinkfinger in gdm again too.

with the following lines in /etc/pam.d/common-auth I get the option to finger swipe but need to press enter.
Is there a way to avoid the need for the enter pressing?

auth sufficient pam_thinkfinger.so
# here are the per-package modules (the "Primary" block)
auth [success=1 default=ignore] pam_unix.so try_first_pass nullok_secure
# here's the fallback if no module succeeds
auth requisite pam_deny.so
# prime the stack with a positive return value if there isn't one already;
# this avoids us returning an error just because nothing sets a success code
# since the modules above will each just jump around
auth required pam_permit.so

I have the same problem (I have T61). I have to press Enter after swiping. That's stupid and i don't know why it doesn't work as in Hardy.

I can reproduce this, so setting the Status to confirmed.

Changed in thinkfinger:
status: New → Confirmed

After creating an xorg.conf file and modifying /etc/pam.d/common-auth,, pressing return is no longer necessary.

However, the fingerprint scanner just plain does not work with some things, gnome-screensaver and gksudo being two of them.

This is with an up to date ubuntu 8.10 install on a Lenovo X61 tablet.
