I installed a fresh UBUNTU 20.04 on my DELL XPS 13 9310 today. Then I registered some fingerprints on the device (on the default Gnome-style desktop). The fingerprint login worked well several times. After that I installed KUBUNTU-full, using the terminal command. Now I have both PLASMA and UBUNTU options to log into, but the **fingerprint reader does not work !!!** The sequence of activities indicates that the error is in the KUBUNTU code. Please help! STEPS TO REPRODUCE 1. logout 2. place finger on FP reader 3.

It appears that there is an issue with the driver. First of all make sure to install libfprint-2-tod1: sudo apt install libfprint-2-tod1 XPS 9310 fingerprint reader needs proprietary drivers to work which you can get here: http://dell.archive.canonical.com/updates/pool/public/libf/libfprint-2-tod1-goodix/ You would want to download `libfprint-2-tod1-goodix_0.0.6-0ubuntu1~somerville1_amd64.deb` then move to the folder where you have downloaded the file and run: sudo dpkg -i libfprint-2-tod1-goodix_0.0.4-0ubuntu1somerville1_amd64.deb Reboot and check if the fingerprint options are shown in User settings. Now you should be able to add your fingerprint(s). If this doesn't work for you, consider downgrading fprintd to version 1.90.9-1. Also you could try to add them manually using `fprintd-enroll`. Now assuming you have enrolled your fingerprint(s). You can check if the fingerprint is working for lock screen and login screen. Keep in mind that login in with fingerprint works but it won't unlock the KWallet so I recommend login in with password, but you can unlock screen or use approve sudo commands with fingerprint. In case this is not automatically setup by KDE you can do: sudo pam-auth-update (use space bar to enable the "Fingerprint authentication") In case this command doesn't work either, you can edit the .pam files manually and the following at the beginning of the file. File: /etc/pam.d/sddm ``` auth [success=1 new_authtok_reqd=1 default=ignore] pam_unix.so try_first_pass likeauth nullok auth sufficient pam_fprintd.so ``` (Login screen. First line ensures that a password login will automatically unlock KWallet, second one adds support for fingerprint.) File: /etc/pam.d/kde ``` auth sufficient pam_unix.so try_first_pass likeauth nullok auth sufficient pam_fprintd.so ``` (Lock screen. The first line looks different from the corresponding /etc/pam.d/sddm configuration because the KDE lock screen does not need to run the KWallet pam module.) File: /etc/pam.d/sudo ``` auth sufficient pam_unix.so try_first_pass likeauth nullok auth sufficient pam_fprintd.so ``` (Sudo commands.) You can also check for other files inside /etc/pam.d/ folder if you would want use fingerprint for other stuff. Hope this helps.

Thanks but no thanks. I followed your instruction up until Reboot and check if the fingerprint options are shown in User settings. Now you should be able to add your fingerprint(s). If this doesn't work for you, consider downgrading fprintd to version 1.90.9-1. Also you could try to add them manually using `fprintd-enroll`. Now assuming you have enrolled your fingerprint(s). You can check if the fingerprint is working for lock screen and login screen. Keep in mind that login in with fingerprint works but it won't unlock the KWallet so I recommend login in with password, but you can unlock screen or use approve sudo commands with fingerprint. In case this is not automatically setup by KDE you can do: sudo pam-auth-update (use space bar to enable the "Fingerprint authentication") I enrolled two figerprints. Logging in after "lock" worked - almost: I had to press "enter" and then got a prompt to touch the fp device. That was ok. Then I tried to log out and log in -- and theh sytem is **now frozen**. I am unable to log in in any way I can think of!!! How can I revert to my working system, from 10 minutes ago?

By the way, your instructions were a bit incorrect. you wrote: sudo dpkg -i libfprint-2-tod1-goodix_0.0.4-0ubuntu1somerville1_amd64.deb should be: sudo dpkg -i libfprint-2-tod1-goodix_0.0.6-0ubuntu1~somerville1_amd64.deb Anyhow, I entered the BIOS setup with F2 and unchecked the fingerprint reader options (two of them).

Hi Amnon, Sorry to hear something broke. This is unexpected. Please enable fingerprint sensor inside BIOS to see if the errors go away. Were you able to login with password after you disabled fingerprint sensor inside BIOS? If you were able to, then you can change these settings without using live usb image. If not, then you will need to install a live image on the usb and mount your disk to edit /etc/pam.d/sddm You can download any distro on your image and boot from it. Then you can follow these instruction to mount the disk: https://discovery.endeavouros.com/system-rescue/arch-chroot-for-efi-uefi-systems/2021/03/ note, you don't have to do arch-chroot, you can only mount the root partition and edit the files. Open /etc/pam.d/sddm and see how it is configured. It should look something like this: ``` auth include system-login -auth optional pam_gnome_keyring.so -auth optional pam_kwallet5.so account include system-login password include system-login -password optional pam_gnome_keyring.so use_authtok session optional pam_keyinit.so force revoke session include system-login -session optional pam_gnome_keyring.so auto_start -session optional pam_kwallet5.so auto_start ``` Please post how the file was configured before removing anything. If you see one of these lines in the beginning of a file remove them and reboot: ``` auth [success=1 new_authtok_reqd=1 default=ignore] pam_unix.so try_first_pass likeauth nullok auth sufficient pam_fprintd.so ``` Now you should be able to login with password. Additionally, you could review other files inside /etc/pam.d to see if they are configured to support fingerprint authentication and remove it if you want that.

Currently my computer is working fine. There is only the error message when booting. I will try your proposed remedies later (not today). Is there anything in them that might cause my system to break down?
Since you encountered errors after changing settings inside BIOS they should disappear after changing back to what they were before. Enabling fingerprint login shouldn't freeze your computer, in worst case I would expect you to not be able to log in with fingerprint. After you show what is inside /etc/pam.d/sddm we can see is there something with the configuration. It would be probably be best to configure this manually as I instructed earlier (in case the first option didn't work).

Thanks! I will try these remedies later this weekend. I need this (and my desktop computer) functioning stably for use in my "day job" in mathematics (see https://sites.google.com/view/amyekut-math-bgu/home ...) .

The result was that I was *not able to log in !!!* I got the error messages twice, then the login screen, but after entering the password the machine froze. So I had to manually reboot usong the opower button. Then F2 => BIOS => disable FP reader. See the uploaded screenshots (video and stills). For now I have a woking system (and only the annoying but possibly harmless error messages upon booting). Will send you the copies of the various files you requested. Not doint anything else for now (for fear of catastrophy).

The file /etc/pam.d/sddm (no changes made by me today) is in the last attachment.
Created attachment 152582 [details] copy of pam.d/sddm
Hi Amnon, Thank you for providing the files. as far as I can tell nothing is changed inside them. It seems that pam-auth-update changes the configuration using packaged profiles. Assuming that you still have fingerprint reader enabled in BIOS, boot the machine and when you reach the sddm (login) switch to different TTY instead of logging in through sddm. You can switch to different TTY using this combination of keys: Ctrl+Alt+F3 (you will maybe have to use function 'fn' key to use F3 instead of volume up). Now login with your username and password and run: sudo pam-auth-update Disable "Fingerprint Authentication" using space key and then reboot. If you disabled the fingerprint reader in BIOS you can just run the command without switching to a new TTY.

I ran the "sudo pam-auth-update" and removed fprint auth. That had no effect on the functionality as far as I can see. I have: - a working system - no FP login - the error message is there, but as you say, it is related to another component.
Hi Amnon, now that you have removed fprint auth, can you login normally (with password) when fingerprint reader is enabled in BIOS? This was meant to fix the issue you encountered while trying to log in while fingerprint reader is enabled, that last comment was not meant to setup fingerprint authentication. Please confirm if the issue with sddm freezing is resolved now so we can proceed with enabling fprint auth manually without pam-auth-update.

I enabled fingerprint login in BIOS (checked the two boxes there). *The booting works well* (same as before enabling that). (Still getting the MKTME message, about which I filed a bug with UBUNTU)
Okay I made live persistence image of kubuntu to try this because this is highly unusual to me since I use Arch. Same thing happened to me when logging in after enabling fingerprint authentication but I managed to fix it. This is basically what you need to do: sudo pam-auth-update -> enable fingerprint authentication Then edit `/etc/pam.d/sddm` with your favorite editor: sudo vim /etc/pam.d/sddm I have commented following line: @include common-auth and added 2 new lines so it looks like this: ... auth [success=1 new_authtok_reqd=1 default=ignore] pam_unix.so try_first_pass likeauth nullok auth sufficient pam_fprintd.so #auth sufficient pam_succeed_if.so user ingroup nopasswdlogin #@include common-auth ... At last, reboot. Now I can use fingerprint to login after pressing Enter in password field. Also works for lock screen and sudo commands. Also make sure fingerprint reader is enabled in BIOS.

I don't know whether things are related or not -- ever since I started experimenting with the FP login, my system is deteriorating: first that odd error message on boot, and today I lost the ability to switch keyboard layouts (between English and Hebrew). I think I will have to reinstall my system from scratch -- a fresh installation. Any thoughts?
@zzrakic: Regarding my keyboard layout problem: I found a way around it (temporary fix), and filed a bug: https://bugs.kde.org/show_bug.cgi?id=460295 So I will not have to reinstall my system any time soon (I hope). When free time comes my way I'll take a look at your proposal... AY
