Update broke keyboard on a Fujitsu Lifebook

[Leo Thomas]

After an update that I performed on my Ubuntu 22.04.3 on the 11. of September, the keyboard of my Fujitsu Lifebook (model E5410) stopped working (a USB keyboard however could be used as a temporary workaround).

I have brought up this issue in the ask-ubuntu-forum as well: https://askubuntu.com/questions/1485408/keyboard-not-working-after-update

Here I was recommended to reach out to you.

I do not think this is a hardware issue as the keyboard functions as expected when I enter the GRUB menu or the BIOS.

During the update in question my Notebooks Kernel was upgraded to 6.2.0-32 (I think from 5.19.0-50-generic). I have grepped the lines from /va/log/dpkg.log into the file "dpkg_log.txt" and attached here. Other attachments are the ones recommended somewhere on the Ubuntu-wiki, namely:

$ uname -a > uname-a.log
$ cat /proc/version_signature > version.log
$ dmesg > dmesg.log
$ sudo lspci -vvnn > lspci-vvnn.log

If you need any more information, do not hesitate to contact me. Also, as I am not too knowledgeable on these-hardware-related issues I would appreciate your assessment: is it worthwhile doing a clean reinstall of the OS?

For now I have helped myself with a kernel downgrade to 5.19.0-50-generic which fixes the keyboard whenever I need it but is still bumpy (currently no launchpad-, webcam- or sound-functionality).

Thank you!

Ah and: I would have liked to report this issue using "ubuntu-bug linux" as recommended, but I ran into a GTK-related error that I was unable to solve.

Update: The issue did not persist after upgrading to 6.2.0-33-generic!
