Title:
Keyboard doesn't work on a "cold boot" with built-in "i8042 PC
Keyboard controller" (ASUS UM425UA)
Status in linux package in Ubuntu:
Incomplete
Bug description:
ASUS UM425UA internal keyboard doesn't work on a "cold boot" (first
power-on). It activates only after restart.
I noticed it when tried to boot live image of Ubuntu 20.04.3
This problem probably appeared with kernel version 5.9 or 5.10 because with
Ubuntu 20.04.2 live image (Linux 5.8) keyboard loads fine. Tried kernel 5.14
and it's still affected.
I tried to recompile kernels 5.11 & 5.13 with SERIO_I8042 set as a module (as
suggested in an Arch Linux bug report) and keyboard now works from the first
start.
In "make config" the changes are:
Device Drivers ->
> Generic Driver Options -> [ ] Support for uevent #may slowdown boot,
needed only for U14.04
> Input device support
> Keyboards -> [M] AT keyboard
> Hardware I/O ports -> [M] i8042 PC Keyboard controller
It changed such lines in config:
CONFIG_KEYBOARD_ATKBD=m
CONFIG_SERIO_I8042=m
CONFIG_SERIO_LIBPS2=m

P.S. Other option which helped me was a GRUB parameter "i8042.reset=1"
but it had a positive effect only with kernel 5.11
