Fingerprint on KDE Neon

Help
1

Hello, I need some help. I used KDE Neon for a few days on another laptop and I managed fine. Now I installed it on my primary laptop (HP ProBook 450 G7), and the first thing I wanted to set up was security — login. I don’t have the option for fingerprint in the settings. I tried some sudo commands and everything seemed fine, but the “enroll” option doesn’t work. ChatGPT tells me that this reader is not supported on Linux. I find this unbelievable??? In 2026, a fingerprint reader on a laptop that is just a few years old can’t work? Please? I really need help, whatever it takes. If necessary, I’m ready to pay someone to set up the fingerprint reader so it actually works. This is the only thing I want to work on Linux.

When I run lsusb in the terminal, it shows:
Bus 001 Device 004: ID 06cb:00b7 Synaptics, Inc. Fingerprint reader [HP G6]

This will be mostly a hardware support issue, as the pieces iirc are all there for this, once libfprint is installed.

But libfprint needs to provide support for your specific reader, and many simply do not, or cannot.

It looks like yours is one of those, unfortunately.

Unfortunately, Linux support for fingerprint devices is not as good as the support for other hardware devices.
They say it covers the fingerprint devices used in Thinkpad and some Dell laptops mostly.
I bought a new laptop recently with a fingerprint device embedded in its touchpad, and it’s not even seen by my system, but I was expecting this to happen, and I didn’t mind.

Some hardware vendors are really complicated.

I once had a Sony Vaio which I bought because it was an excellent device with great Linux compatibility out of the box, but for the finger print reader.

The chip itself would have been nicely supported but Sony had insisted on a modification so that it would only work with Sony’s own driver (which of course they did not release for Linux).
