Keyboard/touchpad unresponsive after 5.8/20.04 upgrade

[Owen Cameron]

I recently replaced broken screen on HP Spectre x360 G2, and upgraded to 5.8 (Ubuntu 20.04). Keyboard and touchpad became unresponsive - but only after booting. Booting with old kernel (e.g. 5.4.0-42) restored full control. Also, disabling acpi restored control (but one wants to see battery level indicator so this hack is insufficient). Evidently, it is not a hardware problem.
Works fine with external keyboard and mouse.

A similar bug from previous distro: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1894125

This issue, including my troubleshooting, is otherwise documented here:

Seems many others had similar issues with 20.04 upgrade - some with only touchpad issues. (Many now marked as duplicates)

Can someone help me fix this issue please?

@gemini127 I don't have the expertise but happy to help where I can. Do you?

[Matthew (gemini127)]

No. It was my first time ever installing Linux. I wiped a low budget laptop that previously had windows, after installing the Linus os, the trackpad was unresponsive. Has been still after installing new updates for Ubuntu everytime the updates come out. This happened almost a year ago. Sent from my Verizon, Samsung Galaxy Note 10 Plus smartphone
