After f32 update on Acer Laptop: built-in keyboard not working

Update:
I tried several distros and finally installed the Fedora Compiz Mate Desktop. It works fine with built-in-Keyboard working. But running sudo dnf update installed me a newer kernel, where I have the same issures. I roughly checked some journal-entrys, but it looks quite the same.
Actual workaround: I manually select the older kernel and the built-in-keyboard is working.
In grub-menu

• the newer kernel, built in keyboard not working: Fedora (5.7.14-200.fc32x86_64) 32 (thrirty-two)
• the older kernel, built in keyboard working: Fedora (5.6.6-300.fc32x86_64) 32 (thrirty-two)

I’d like to follow @rickhg12hs suggest and

• downgrade the older kernel

or

• find way that grub will take the older kernel for default.

How can I do this?

Additionally I’m glad to have any suggestions, that further kernel-updates will be prevented, what do you think of sudo dnf update --exclude=kernel* (found here)

Looking forward for your help!

Hi there!
I’m quite new to Fedora and asking for your help with a keyboard issue.

Recently I updated my laptop from fedora 31 to fedora 32. When I tried to type my password on lockscreen I realized, that the build-in keyboard of my laptop isn’t working. Log in with external USB-Keyboard worked. [I already know that my touchpad is broken for some reason].

GNOME-Version 3.36.3., Fedora 32, Wayland, up to date

My Laptop: Acer Aspire E5-511-P7AT; Intel® Pentium® CPU N3530 @ 2.16GHz × 4; Intel® HD Graphics (BYT)

Update everything with sudo dnf update hasn’t solved the problem.

The Keyboard is working in BIOS. Therefore I assume, that the problem might be connected with libinput.
Terminal Output (selection):

AT Translated Set 2 keyboard seems to be the built-in keyboard. Running sudo libinput debug-events in terminal gives:

Pressing any key on the built-in keyboard give no respond in libinput debug-events, exept for some FN-keys (event4).

What can I do now to get this built-in keyboard to work?
I’m looking forward for your help.

Best regards
