Make install failed

After reinstalling my Matebook I also had to apply your patch again. But it failed with the following error

╰─➤ sudo make install

Do you have any idea what's missing and how I can solve the problem? I use Manjaro 18.1 with the 4.19.16.1 kernel. Thanks!

I don’t see any errors with the build process, it’s complaining about missing keys. Make sure you’ve disabled secured boot in your BIOS and have ca-certificates installed. Try lsmod | grep wmi and see if the module is loaded.
You could also try using PKGBUILD from here.

I had installed the ca-certificates. But probably the kernel requires to sign drivers before install.
As alternative I tried now to install it with using dkms and this was running without any problems and after a reboot all fn keys worked perfectly. Thanks!

So with the help of here I have now also sound from both speakers.

There's only one last thing, which we can't use on Linux. It's the finger print sensor for authentification and I'm very curious if this will also work some day.

[aymanbagabas]

No problem! Since the PKGBUILD works for Arch based distros, maybe someone could maintain the package on AUR. This would be really helpful for other people. I'm really glad that a patch has been published for the sound issue, that's great news!

Regarding the fingerprint sensor, I've been fiddling around with it lately and trying to reverse engineer the driver on Windows but no luck yet. I was able to get some data back, however, nothing useful. I will continue working on it whenever I have time.

So, the Goodix FP 3288 (found on MBX) and 5187 (on MBXP) work along with a common SPI device "Synaptics Fingerprint Sensor SYNA8001". First, we gotta write a driver that exposes these devices to the system, then the reverse engineering part comes in to write the actual driver that interacts with user-space (mainly libfprint) which is the hard part.
