Hello, I'm using Ubuntu 17.10 on my Spectre x360, almost everything works with a fresh installation, but the fingerprint reader. I couldn't even find the device and tools like this won't recognize the hardware device.
At least, I'd like to know the fingerprint reader specifications (brand and model).

I am very interested to know about your expeience with spectre and Linux. I am considering getting a spectre sometime soon.
Did you figure out a way to get this information for the fingerprint reader?
Providing good hardware with Linux support is a good selling factor for many developers. I really hope HP puts more effort in providing better linux support, compatible hardware or just enough information so that others can make it work.

oops, I thought it is a usb device.... just like my HP Elitebook 9470m which has a Validity Sensors and can be seen by "lsusb".
So, if lsusb do not get us the right info, let's try lspci :)

Yeap, already tried but I couldn't find anything related to fingerprint reader or sensor.

Hi @dariosm, after I got my spectre x360 13, I have done some research on it.
Firstly, I logined in windows and find out the Fingerpring Sensor Device is an ACPI device whose BIOS device name is
Then I went to Linux to check something, and wrote a little script:
#!/bin/bash # Print DMAR info from dmesg sudo dmesg | grep -i dmar
# lspci: show the device from dmesg echo -e "\n\n" lspci -vv -s "00:1e.2"
# Search the ACPI device with SPI in it's path echo -e "\n\n" for i in `ls /sys/bus/acpi/devices`; do cd /sys/bus/acpi/devices/$i; grep -q -i spi path 2> /dev/null; if [ $? -eq 0 ]; then echo ====================================; echo "/sys/bus/acpi/devices/$i"; cat path; fi; done
Finally, we got some output:

So, as we can see, Linux had successfully found the device(SYNA8003, the same device name like what in Windows), but got no driver to handle the device here. I searched this keyword with Google but hardly found anything useful.

Great work, @kings_way! I'm subscribed in hopes of a solution. No worries for me, though, if I never get the fingerprint reader working. I am SUPER happy with Ubuntu 18.04 on this HP Spectre x360 (15-ch011-dx).
