Hi,
I just bought a Lenovo yoga 6 with ryzen 7 5700U. And I have installed opensuse tumbleweed on it with gnome desktop but I can’t find any fingerprint unlock settings like mentioned here
About a month ago we had a discussion about fingerprint readers on the users mailing list. Not all readers are supported. I don’t use gnome so I can’t guide you with it but you should first check if your reader is supported. I made a small script to check it.
myreader=`lsusb | awk '{print $6}' | xargs`
supported_readers=`w3m -dump https://fprint.freedesktop.org/supported-devices.html`
for i in $myreader;do echo $supported_readers | grep -i -o $i; done
If you don’t get a response, your reader is not supported.
Make sure you have these installed.
zypper se -x usbutils gawk w3m
I know my finerprint sensor is goodix which is there in this list
https://fprint.freedesktop.org/supported-devices.html
but running
lsusb | awk ‘{print $6}’ | xargs doesn’t show any results 
The row was not correctly copied. Change to an apostrophe.
Like this:
lsusb | awk '{print $6}'
oh yes. then it prints:
1d6b:0003 0bda:4853 1c7a:0576 1d6b:0002 1d6b:0003 5986:2146 1d6b:0002
Please, make it yourself and us easy and do not type those stories, but simply include the prompt/command line, the output and the next prompt line within your copy/paste. IMHO easier then all that typing.
E.g.
boven:~ # lsusb | awk '{print $6}'
1d6b:0003
0bda:0153
03f0:0941
04ca:004b
03f0:7e04
0bda:b008
1d6b:0002

I’m quite sure your reader is this one: 1c7a:0576, LighTuning Technology EgisTec EH576. Not supported as far as I can see.
See this
https://linux-hardware.org/?id=usb:1c7a-0576
And this
https://gitlab.freedesktop.org/libfprint/wiki/-/wikis/Unsupported%20Devices
yes, i guess. sadly.
My device is this one:
| Device | LighTuning Technology EgisTec EH576 » |
|---|---|
| Computer | Lenovo Yoga 6 13ALC7 82UD |
If you’re up for it and willing to put in the effort, someone actually started making a patch for libfprintd.
