Laptop Keyboard not working after kernel loading - HP Spectre 360x

[thatent]

Hello everyone!

I have a HP Spextre x360 - 13-w010 laptop. I’ve had it for years and EndeavourOS was working flawlessly for at least 3 years.

Until, in June (2024), the laptop’s integrated keyboard and mousepad, as well as the laptop’s touchscreen, stopped working. External keyboards (USB) work fine. I suspect this started after a kernel update. (I’ve always used the ‘normal’ kernel, not the LTS).

The keyboard stops working as soon as I need to enter my LUKS decryption password.

Everything works fine in the BIOS (which is password-protected, and I can enter the password without issues), and also when I run a windows bootable installation USB, keyboard and mousepad do work as expected.

The Linux-based live USB sticks I tried do not work. (Mint and Ubuntu).

I installed the LTS-kernel, selecting this in systemd-boot makes no difference.

I read quite a few topics on this forum and on other places around the internet.
Loading kernel options seems to be my best bet, but I don’t exactly know how to do this. So I have a few questions about this.

Which kernel options would I be recommended to try?

Also: do I have to add “=1” (so add “i8042.reset=1”) to the options I try?
So I would add this to the end of the options line?
(I use systemd-boot)

I do understand that if I find ‘the option’ that works, I think I should add it to /etc/kernel/cmdline and then reinstall the kernels.

If the keyboard worked well for years, how likely is it that it will start working again without the need for kernel options? It’s not been working for a little under half a year now; I’m also very surprised that live environments based on older kernels (such as Ubuntu) don’t work either.

Thank you all very much in advance for any ideas or suggestions you might have!

I’m just putting this here in case anyone finds this topic through a search engine.

After about half a year of hauling around a separate USB keyboard, I can finally use my laptop properly again!

This forum post on the Linux Mint forum pointed me in the right direction.

Quoting the solution:

I just wanted to let you know that I was able to get my HP keyboard to work in the latest OS. It just took this:

1. cd /etc/modprobe.d
2. edit file blacklist.conf (Or, I think I could have edited or added a new .conf file to this directory)
   I used: sudo nano blacklist.conf to do this
3. add the line: blacklist intel_ish_ipc to the file
4. The following was NOT necessary! → run: sudo update-initramfs -u
5. restart

It turned out kernel modules had nothing to do with it (I tried every combination of the i8042 kernel options and none of the had the desired effect).
Blacklisting the intel_ish_ipc did the trick! (it does disable the touch screen though, but at this point I’m just happy to have the keyboard and mousepad!
