After Ubuntu is installed on a computer, it can run perfectly without any drivers, especially the latest version of Ubuntu. However, fingerprint recognition has always been a small pity.

Hey, everyone knows that I am a GUI controller and I am mostly lazy. This article describes how to add a fingerprint reader to Ubuntu by using only the graphic interface. It mainly supports some models such as ThinkPad and Vaio.

1. Add the PPA software source

I would like to thank David Jurenka, the hero behind the scenes, for saving us so much time.

Open System> Administration> Software Sources and add the following under the Other Software tab:

Ppa: fingerprint/fprint

Reload the Software List as prompted.

2. Install and test the FPrint fingerprint recognition software

Open Applications> Ubuntu Software Center, search for fprint-demo in the search box, and install the first item.

After that, open the Applications> Accessories> fprint project demo and check whether the device can be found.

If you can, continue. If not, delete fprint-demo, remove the PPA source, follow the instructions on this page, and configure the Fingerprint GUI, which contains non-free packages, more hardware is supported, but less integrated with GNOME. (I think it's really a fake copy ...)

3. Install the PAM module

Open Ubuntu Software Center, search for and install libpam-fprintd.

Check whether/etc/pam has been modified. d/common-auth. If no, no operation is required. Otherwise, press Ctrl-Alt-T to open the terminal and run sudo pam-auth-update -- force.

Iv. Registration fingerprint

Choose System> Preferences> About Me and click Enable Fingerprint Login... (Enable fingerprint login ...)" And follow the prompts.

V. Several Questions

If you select "encrypt my/home folder" during installation, this method cannot be used because your fingerprint is stored in ~ /, But to read it, you must first decrypt it with a password.

Sometimes, for example, to open software such as the new software package manager, you need to manage permissions. In this case, they use gksu, but it has some bugs, so you can see a new "starting..." in the lower panel ..." But there is no actual content. In this case, please print your fingerprint. No solutions.
