10-15 Second Keyboard Unrecognized Issue

A family member bought a new laptop (HP Pavilion 15-eg0073cl) and asked me if I could put Ubuntu on it. I installed 20.04.2 this weekend and have noticed that the keyboard doesn't accept any input on the login screen for about 10-15 seconds (sometimes more) after a cold boot. After that time, I'm able to use the keyboard just fine. Issue also manifests when activating the lock screen and waiting for a minute or two. After waiting for 10-15 seconds, the keyboard is recognized again and behaves normally.

I installed the "Ubuntu Mainline Kernel Installer" application and tried the 5.11.6-051106-generic kernel (newest one available at the moment) just to see if that would help fix the issue (p.s. Secure Boot has been turned off). The behavior of the issue is still the same. It's worth noting that there is no delay if I plug in a USB keyboard and boot like outlined above in case this is useful information.

I hesitate pasting all 500+ lines of output from lshw and I'm not sure what information would be helpful to share from that. I installed and ran hwinfo. Here's a section from that output that I think might give some more info on the keyboard:

I appreciate any thoughts you all might have in advance. Thank you! :)

EDIT: I installed the 5.13.0 kernel last night and the issue still seems to persist. I'll keep updating kernels as they release.

Solution 1:

So I've got a similar issue with HP 15s-fq2032ua (48V94EA). Keyboard activated with a huge delay (up to ~160s). Pressing some KB keys probably helps to activate it faster. Luckily I've found a workaround and didn't notice any side effect from it yet

It's a GRUB/boot option

i8042.nopnp

sudo nano /etc/default/grub

add option chaging

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

to

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i8042.nopnp"

Save with Ctrl+X; then "Y"

sudo update-grub

Actual result

Before:

sudo dmesg | grep i8042

...

[    0.466661] i8042: PNP: PS/2 appears to have AUX port disabled, if this is incorrect please boot with i8042.nopnp
