On Dell XPS 9305, ubuntu 20.04 LTS, it dont work. Added sources list as suggested and installed the packges oem-somerville-melisa-meta libfprint-2-tod1-goodix oem-somerville-meta tlp-config.

lsusb |grep oodix

Bus 003 Device 005: ID 27c6:5335 Shenzhen Goodix Technology Co.,Ltd. Goodix Fingerprint Device

fprintd-enroll

list_devices failed: No devices available

Alas, my only guess is that 9305 has a different device, ID 27c6:5335, that is not supported by that driver.  Mine (9300) has ID 27c6:533c and works fine...

it seems strange cause Dell XPS 13 9305 (i7), which I understand to be internally identical to the 'supported' XPS 13 9310 other than the screen dimensions (16x9 rather than 16x10 for the 9310).

Have tried installing both 20.04 LTS and 21.04 with no luck.

Maybe I'm installing the correct drivers but have not signed them properly for operation under Secure Boot?

For other drivers, once rebooted the laptop asked me for the generated password, for these drivers once rebooted didn't ask it.

The driver should be signed (if you added the repository key mentioned in the original recipe) so that shouldn't be an issue. If you look here, https://launchpad.net/libfprint-2-tod1-goodix however, you can see that your device is not supported by the driver, so I am afraid that your understanding that 9305 is internally identical to 9300 is not quite right...

unfortunately as you said isn't a signature problem, the problem is related to driver, so all that remains is to hope for a future development of the driver for my model, thank you for your interest, i am more afraid than you relating to your understanding regarding my post, cause i was referring to 9310 not 9300...

Thanx DanielNTX. Everything loads fine and it looks like it works. When I run "fprintd-enroll rick", I get the messages: 

Using device /net/reactivated/Fprint/Device/0
Enrolling right-index-finger finger.
Enroll result: enroll-stage-passed

So far, so good. But, then the program just waits for more input. I can scan the same or other fingers and again receive: Enroll result: enroll-stage-passed. But the program never ends unless I ctrl-c.

Then, "fprintd-list rick" returns: 

Device at /net/reactivated/Fprint/Device/0
Using device /net/reactivated/Fprint/Device/0
User rick has no fingers enrolled for Goodix Fingerprint Sensor 53xc.

There's lots of data written to the /var/lib/fprintd/goodix files but apparently something isn't matching an expected entry.

Does anybody have any suggestions?

Thanks in advance.

HI!, 

I am having trouble with ubuntu 22.04 and my dell xps 9310, I have added the ppa and installed the drivers mentioned at then begining of the post but had no luck..

Thanks in advance!

Hi!

Is there any script to add the appropriate repository for Ubuntu 22.04?

No not yet.  I had no problems upgrading from 20.04 to 22.04 and my fingerprint sensor and IR unlock still works with Howdy.

You can view the current Jammy dists here: http://dell.archive.canonical.com/dists/

And you will see it for code name minccino, omastar and tentacool 

Thanks. It happens that I will replace Windows with Ubuntu 22.04. So in my case it won't be an update.

Do you know what these codenames mean?

Hello cleiconde, did you solve your problem with fingerprint sensor and Ubuntu 22.04 LTS on Dell XPS 7590?
If it is the case, please share your solution.

are there any updates of it?  i tried to install above packages but:

The following packages have unmet dependencies:
oem-somerville-melisa-meta : Depends: linux-generic-hwe-20.04 but it is not installable
E: Unable to correct problems, you have held broken packages.

And of course i have the newest kubuntu (not 20.04)
