Validity Fingerprint Reader Linux

[ Edited ]

Hi,

I was wondering, whether there are actually some Lenovo guys around, or at least people who can get in touch with them.

Many people have been trying to get the new fingerprint reader (by Validity / Synaptic) to run under Linux. However it seems, that there simply is no driver around.

I'm talking about the fancy new fingerprint reader found in the current Thinkpad generation (Yoga X1, X1 Carbon, X260, X460, T460s, T460p).

The linux community already tried to develop some driver, however it seems, that the traffic is encrypted. The only, however very tiresome possibility would probably be to port the Windows driver... See https://bugs.freedesktop.org/show_bug.cgi?id=94536 for infos.

However in the recent years Lenovo did quite some good work for Linux support, thus I was wondering, whether it would be possible for this to continue.

 

Greetings,

grb19

Re: Validity Fingerprint Reader Linux

I will pass this along to our Synaptics rep to see if I can get any comment.

Any update? This issue also affects P50/P70 machines, and has been discussed in a few other threads repeatedly. It would be nice to have Lenovo official support for the FP and color calibration drivers in Linux. Thanks.

Re: Validity Fingerprint Reader Linux

Synaptics does not have any linux driver for the new touch-style fingerprint sensor in P50/P70/T460s/etc.  There is nothing for Lenovo to release or support.

Re: Validity Fingerprint Reader Linux

Dear Lenovo Staff
Thank you for your answer but it seems that a lot of customers are impacted by this choice made by Lenovo.


It is not a scoop that several X1 users works on Linux and this is also a part of your job to ensure that the hardware used in your laptop will be usable on the most representative systems..

So from my point of view Lenovo made a bad hardware choice and should try to offer a solution to their customers....

 

Thanks in advance for your support....

Re: Validity Fingerprint Reader Linux

I agree with fmarignier.

 

Lenovo is Synaptics client, and as such should have enough access to reach them and see if they can create a Linux driver. Otherwise, they should have chosen another supplier.

 

Linux is important.

I would propose to mark thread "NOT solved" as there are no solution. Currently thread gives false impression like it is solved but it is not.

 

Regarding Synaptic touchpad and Linux:

https://wiki.debian.org/Synaptic

https://wiki.archlinux.org/index.php/Touchpad_Synaptics

etc...

... so I would say that it is working well in Linux.

 

There is Fingerprint Team - https://launchpad.net/~fingerprint - I propose to cooperate with them and ensure that your fingerprint sensor drivers are available through that and other corresponding distros repositories. Currently the ID 138a:0090 is missing there.

 

There is also (a bit outdated) http://www.thinkwiki.org/wiki/Integrated_Fingerprint_Reader which tells that usually fingerprint sensors are working on Lenovo laptops but somehow a non-supported vendor has been chosen...

Re: Validity Fingerprint Reader Linux

Exactly,
It 's a bit difficult to accept that there is no solution because Lenovo made a wrong choice.
It seems that it will be not possible to build a driver based on a reverse engineering approach.
So, our last ressort is to ask Lenovo to take "this problem" in charge.

Please Mr Lenovo could you help "your" customers

Yeah, I would like to see a "Solved" mark when this issue is really solved. 

 

Beside reverse engineering, what information do you guys think exactly is needed to make a Linux driver for the FP reader? Maybe Lenovo can collaborate with the FP reader venders to get some IO standards and so on... Just to make it clearer to solve.

Re: Validity Fingerprint Reader Linux

Yes of course, Lenovo could be able to work with synpatics to create a driver for the 138a:0090 device.

I hope that synaptics not need to use reverse engineering to provide a driver Smiley Happy

 

But I heard some things about a team that tired to use a reverse engineering approach to provide a this driver but encountered an encryption problem. This is not relevant in our case, sorry.
