Notebook keyboard doesnt work with Ubuntu

Asked by Casimir Castor

On my Medion Akoya S15449-MD61991 Notebook the keyboard doesnt work with Ubuntu 20.04 nor other linux distribucions (Fedora, Mandriva). It neither works with Free BSD nor open Indiana. Ubuntu is the system which I use always as main system. The other systems I actualy only install in the virtual box. But to test if it is only a Ubuntu specific issue or Linux in generell I tried it also with the other systems. But with the same result.
The prolem is not the hardware because in the UEFI the keyboard works correctly. And in grub it is working too. But when the installation starts it is not possible anymore to make any keybord input. Finaly I finished the installation with the screen keyboard. And still now I`m using all the time the screen keyboard. But this can`t become a habit.
Of course I have already searched for possible solutions on the internet. It seems I`m not the only one. Rather it looks like that this issue is a common issue on Medion notebooks. I also found a webpage where they offer a kernel-patch which probably should fix the problem. But because I`m not familiar with theese kind of things and also another user said that the patch didnt fix the problem I hope for another solution of the problem.
It would be nice if anybody got a solution!

Sounds like a hardware issue. On screen keyboard works, multiple OS. Good, defiantly not software.
Did the keyboard strip come out of its connector located under the actual keyboard.
It has a lock that holds the keyboard strip in place locked and properly connected. Is the keyboard faulty needing replaced.

Anyone else please advise.

Thank you for your answer! But it is not a hardware issue. In UEFI and grub the keybord is working correctly. Only operating systems can`t identify the keyboard. I think it is a driver or a kernel issue??

Does an external keyboard work (connected via USB)?

Didnt try an external keyboard yet because I ain`t got one. I will get one to try. But I already think that it will work without any problem because all USB- devices working correctly.

More possibilities for diagnostics:

Does the output of the commands

lsusb
lspci

show anything that might be the keyboard?

I tried with a USB-keyboard and it worked perfectly.

This is the output of lsusb:

For my understanding (which is not the best) nothing about the keyboard??

Do you have the latest BIOS?

Yes latest BIOS is installed!

After all my investigations it seems that the problem can be solved only with a future Kernel....
I got the latest Linux-kernel (5.14). But as long as keyboard-drivers for this hardware not included in the Linux-kernel it wont work.

Can you help with this problem?
