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.

I finally found success by installing and booting to the 5.4.18-050418-generic kernel.

Since 5.4 is a longterm support version and ~.18 is only a few point releases below the current stable kernel, I'm happy sticking with this finally. A variety of other kernel versions I tested (both higher and lower) seemed not to recognize the keyboard input. So although it seems odd, it seems specifically kernels 5.4.0-42, kernel 5.4.18, and most of the 4.~ series kernels work.

I used "Mainline" to install the kernel, searching for 5.4.18 and installing it. One more thing: I had to disable Secure Boot to boot to kernels installed this way.

I finally had "success" with my current kernel version 5.4.0-58. This shows the keyring not unlocked first in white on a black screen background on my laptop screen (my hp is the x360 11 n010-nv) and then in white on a black screen background on my external monitor (HP Z24). Waiting a little longer, both the screens change to display to usual theme picture with the keyring not unlocked on my external monitor as usual. I can enter my password on the white keyring not unlocked on my external monitor with the black screen background but ubuntu does NOT display the ******, nor respond until the theme picture appears with the keyring unlocked and ready to go on my external monitor.

I hope this helps other HP X360 11 users !
