Framework 13 - fingerprint support on gnome

Ciphreon

Hi there !

When I installed Solus on my laptop, I was surprised to find that it didn't support the fingerprint reader out of the box, unlike distributions like Fedora or Ubuntu.

Is there a procedure I should follow that I've missed (perhaps a driver)? I saw that I had to install fprint and modify some config files, but when I tested it, it clearly didn't work.

Thanks un advance for your time ^^.

Ciphreon I have a framework and my fingerprint sensor works. I believe you have to install fprintd as it’s not preinstalled.

Ciphreon

uni-dos Did you just install fprintd or did you do something else? I ask this because after installing fprintd, both the terminal and gdm do not take into account the fact that I was able to register a fingerprint :/.

Ciphreon

I've these libraries installed btw.

Sorry for the late reply. I run KDE so I was able to setup fingerprints in KDE settings. What Framework 13 do you have? I have the AMD version and I had to downgrade the firmware for the fingerprint reader, but that was a while ago.

Ciphreon

uni-dos I have the AMD version also. Solus 4.7 with Gnome 47

I've found a solution, simply add the line below to the top of the file located at /usr/share/defaults/etc/pam.d/system-auth. I think I can adjust the second word to optimize it but it works ^^.

auth sufficient pam_fprintd.so

@uni-dos Thanks for you time ^^.

Ciphreon Be careful to not edit any file under /usr directory, because it will get overwrittten the next time the package (which ship these files) gets updated. It is part of our "stateless" design.

You can create the equivalent directory (if not exist yet) in /etc. My guess it will be /etc/pam.d/. Copy the "system-auth" file to that directory and make your modification there.

Tell us if it working or not. Cheers!

alfisya Thanks for the tip ^^. It works ^^.

Cheers ^^/.

FYI this worked on my Dell Inspiron 7445 too - including using /etc/pam.d/ instead of /usr/...

thanks for the tips!

I'm not using a Framework, in my case it's a Thinkpad T14s G1 intel and I needed to install libfprint and fprintd:

sudo eopkg install libfprint fprintd

after that I added the same line:

auth sufficient pam_fprintd.so

at the beginning of the file:

sudo mkdir mkdir /etc/pam.d

sudo cp /usr/share/defaults/etc/pam.d/gdm-password /etc/pam.d/gdm-password

sudo vi /usr/share/defaults/etc/pam.d/gdm-password

Could be added as default in Solus Gnome edition?

I don't understand why but it destroys the gdm defaults in pam.d, so I needed to reinstall gdm

sudo eopkg install --reinstall gdm

alfisya

xose sudo vi /usr/share/defaults/etc/pam.d/gdm-password

You should not edit any file inside /usr. It will be overwritten by next time that package get updated. You should edit the copied file in/etc.
