Dell XPS M1530 fingerprint reader in Linux!!!
Using a fingerprint reader to access your account is better than typing those long passwords again and again in Linux. Some people have said that even if it works in Linux sometimes it doesn’t recognize your fingerprint, well if u swipe your finger “properly” it surly works :). I you have Ubuntu 8.10 then here are a couple of steps that you would need to follow :
First edit your /etc/apt/source.list
sudo gedit /etc/apt/source.list
and then add the lines :
deb http://ppa.launchpad.net/jon-oberheide/ubuntu intrepid main
deb-src http://ppa.launchpad.net/jon-oberheide/ubuntu intrepid main
to the end of the file, and save and exit.
Now in the terminal type:
sudo apt-get update
sudo apt-get install thinkfinger-tools
Now reboot and then try and test the driver by typing the following in the terminal
If it gives an error as
animesh@animesh-laptop:~$ tf-tool –acquire
ThinkFinger 0.3 (http://thinkfinger.sourceforge.net/)

Error while opening “/home/animesh/.thinkfinger.bir”: Permission denied.
Could not open ‘/home/animesh/.thinkfinger.bir’.
Then just try with sudo tf-tool –acquire
Now try and verify it by
tf-tool –verify (use sudo if you used sudo before to acquire your fingerprint)
Now edit your /etc/pam.d/common-auth by typing in the terminal :
To make it look like.
# here are the per-package modules (the “Primary” block)
auth sufficient pam_thinkfinger.so
auth [success=1 default=ignore] pam_unix.so try_first_pass nullok_secure
# here’s the fallback if no module succeeds
sudo tf-tool –add-user $USERNAME
So that you can login using your finger than password
and to use your finger as root password type
tf-tool –add-user root
To unlock the screen saver using your finger is given at this site (as it is not working for many users of 8.10 i have not included it in this post :()
