inbuilt keyboard doesn't work

[wodga]

I have kubuntu-22.04. installed on my fujitsu-lifebook. First all went well. After apt dist-upgrade my keyboard (Fujitsu FUJ02E3, Connected to FUJO2E3/input0) isn't recognized anymore. An external keyboard works well.

Try booting to a previous kernel, and see if it is working there.

THIS may also be worth looking at. More detail here

Thank you very much for your quick help.
For me after sending

modprobe i2c_hid

and

modprobe i2c_hid_acpi​

followed by rebooting, the inbuilt keyboard is working well.

Sorry now I am back with the same problem. Unfortunately it only worked once. Now again I can not use the inbuilt keyboard. None of the described solutions worked. I even tried to load the regarding modules into the kernel with

echo i2c_hid_acpi | tee -a /etc/modules

and

echo i2c_hid | tee -a /etc/modules

Nothing works ...

Does it work if you repeat the commands in post #3

Unfortunately, not even this commands work.
