Ubuntu – Keyboard on HP notebook stops working under kernel 5.4.0-45-generic


The built-in keyboard on my "HP Pavilion 11 x360 PC" stops working in the graphical login under kernel 5.4.0-45-generic on Ubuntu 20.04.1 LTS (Focal Fossa). Booting to the previous kernel (5.4.0-42-generic) works fine. Booting back to 5.4.0-45 breaks it again. I tried running "sudo update-initramfs -u" and "sudo update-grub". An external USB keyboard works under both kernels, but this defeats the purpose of a notebook computer.

  • There is a bug already https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1894017

    As of 6/9/2020 it has been confirmed but it is unassigned.

    A possible workaround is Ctrl+Alt+F3 on a external keyboard.
