Title:
Keyboard and touchpad absent after booting, but not before
Status in linux-signed-hwe-5.8 package in Ubuntu:
Confirmed
Bug description:
After I recently replaced broken screen on HP Spectre x360 G2, keyboard and
touchpad became irresponsive - 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...). Evidently, it is not hardwear problem.
Works fine with external keyboard and mouse.
