Hi everyone,
I am a little flabbergasted today but also really happy. It looks like Dell/Broadcom has finally released a Linux driver for the Latitude 5420.
I saw there was some system information. When i click on it it opens driver manager. I could click to install the Broadcom Fprint driver. After reboot i could assign my finger with frprintd-enroll. En after that i could enable fingerprint login with sudo pam-auth-update.
I think you need to install the Dell repository or download it manually here: http://dell.archive.canonical.com/updates/pool/public/libf/libfprint-2-tod1-broadcom/
If you've got a Dell laptop (Inspiron 5480, 5490 and Vostro 5590) and you are curious to know whether you could activate the fingerprint reader available on those laptops on Ubuntu, I can happily tell you, yes, you can. The reader is not as fas as those on your latest smartphones, but it's usable. I have written my experience here:
https://sslaia.blogspot.com/2020/11/how-to-make-fingerprint-reader-work-on.html
Hope it will work well on yours too.
"The fingerprint doesn't unlock the keyring, so as soon as you login and open Chrome for the first time you'd be asked to authenticate." Does that only apply when booting or even if the computer is just locked?
I've been using both the fingerprint and the IR face unlock on my dell xps 9300 for a while now in POP!_OS 20.10; and it works as expected. Although; not as great as on Windows unfortunately.
If you check the fprint page for supported devices you will see that yours (0a5c:5804) is not included, so you cannot expect it to appear in the fprint-gui. It is just not supported. Page is: https://launchpad.net/~fingerprint/+archive/ubuntu/fprint
The fprint project is not moving anymore, since quite some time, so you should not expect any solution, if you do not start coding (or persuade someone to do it for you).
Sorry, but no luck.
EDIT:
- The exact page of the supported devices by fprint is: https://fprint.freedesktop.org/supported-devices.html
- After 2 years, the Broadcom chips are still not supported.
- I hope someone (Joe? ) might have done some progress with that, but it is not visible in fprint's pages.
- The rest of the proposed solutions (gui) are based on the fprint. So, the outcome remains: Sorry, no luck.
This is just wrong. We should point people at resources not tell them that they're shit out of luck. I also have the same fingerprint reader (though in a Dell e7240) as does another individual who just posted to the fingerprint-gui forum 2 weeks (also with a e7240 but, again, we all share the same fingerprint reader).
This sucks. I've never done any software development for an OS or driver development but I'll look into it and see what I can find out.
Enabling fingerprint for login, screensaver unlock, graphical sudo password prompts in Ubuntu 22.04 on Dell Inspiron 14 7425 2-in-1 requires the following commands:
$ lsusb
...
Bus 003 Device 003: ID 27c6:639c Shenzhen Goodix Technology Co.,Ltd. Goodix USB2.0 MISC
...
$ sudo apt install fprintd libpam-fprintd
$ fprintd-enroll
$ sudo pam-auth-update --enable fprintd
Full details:
man fprintd-enrollman pam-auth-update
I'm also running the same setup and had the same issue but the fix is pretty straightforward. First of all makes sure that the OS recognises that the fingerprint sensor exists. You can do this by running
lsusb
You should see an entry that is about a fingerprint scanner. Then you can download and install the needed software with
wget http://dell.archive.canonical.com/updates/pool/public/libf/libfprint-2-tod1-goodix/libfprint-2-tod1-goodix_0.0.4-0ubuntu1somerville1_amd64.deb
sudo apt install ./libfprint-2-tod1-goodix_0.0.4-0ubuntu1somerville1_amd64.deb
If you get any dependency errors just apt install the relevant dependency and try again. After you install everything you should be able to see a fingerprint option appear in the Users settings. According to the original source there is a reboot necessary.
Hope this helps!
My laptop is Dell Latitude 7410 2 in 1 windows 11. At first, I bought this laptop without the fingerprint reader version. When I opened up the back cover, there's a dedicated socket for the fingerprint reader on the motherboard. So, I decided to buy the exact fingerprint reader sensor hardware and after I installed it, it fits perfectly. The problem now is there is no dedicated driver that can read the fingerprint sensor. I looked online, turns out that I need to install "Dell-ControlVault3-Driver-and-Firmware" that supposedly included the fingerprint sensor. I tried and still no fingerprint sensor driver installed. What should I do?
