The Keyboard appears to be recognized but it doesn’t work. The only thing I can do on the keyboard is using the FN Keys to control the display brightness.
I’ve also tried Linux Mint and it has the same problems. External keyboards are working flawlessly.

Looks like a kernel issue.

found that topic too. They said they applied the patch for the S5402ZA Model aswell, i don’t quite understand if I have to configure something?

[dalto]

It was only merged recently. I don’t follow kernel development closely enough to know when that patch will actually be in production kernels.

If it isn’t there currently, you would need to apply the patch and build the kernel yourself.

Probably this is the patch?

Do you might have a reference on how to apply a patch? I’m a total newb to kernel stuff.

You can easily use the patch command to apply the patch.

The harder part is building the kernel.

Here are the instructions for that.

Okay thanks,
then this should be solved. If you have this laptop model or any other mentioned in the bug thread, you can either wait for kernel version 6.1+ or patch it yourself.
