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

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(R) 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:

-event5 POINTER_MOTION +0.000s -1.62/ 0.00 ( -5.00/ +0.00)

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

Hi @vgaetera, thanks for your answer.

  • I’m running libinput 1.16.0, but built-in keyboard is working. How to downgrade libinput? Probably touchpad will work then …

  • I’ve tried several steps here (askfedora won’t let me edit my original question 6th time).

sudo dnf downgrade libinput

Reboot to apply changes.

Thanks, but downgrade to libinput 1.15.4. didn’t solved it in my case. I even have no sign of my touchpad neither in xinput list nor in sudo libinput list-devices.

Hi. I have the same problem with my asus Q504U keyboard and touchpad after a fresh reinstall of f32, but the problem start after the first dnf update. This means, if I keep f32 without update, everything works perfect. After the update, both keyboard and touchpad does not work at all and, in order to have access to my computer I either connect and external keyboard via usb or use the touchscreen keyboard ob my laptop. Keyboard and touchpad works once on bios, which is curious.
any suggestions?
Thanks in advance

With the latest kernel update in Fedora 32 (kernel version 5.8.11-200.fc32.x86_64) touchpad and keyboard work again on my ASUS laptop (model R541U / X541UAK) :slight_smile:
