[SOLVED] Unable to disable Keyboard by blacklisting module atkbd

I've been searching for ways to disable my keyboard (because it acts crazy at times) before X starts and I've found out the easiest way to do this is by:

echo "blacklist atkbd" > /etc/modprobe.d/blacklist.conf

This works like a charm on linux-zen 5.9 on before. But as of, 5.10, the said method no longer works and I'm at lost.

Re: [SOLVED] Unable to disable Keyboard by blacklisting module atkbd

https://github.com/archlinux/svntogit-p … 516073c12#

CONFIG_KEYBOARD_ATKBD=m
CONFIG_KEYBOARD_ATKBD=y

it acts crazy at times

How "crazy"?
Tried to pass "atkbd.reset=1" to the kernel?

Can you elaborate more regarding the replacement of CONFIG_KEYBOARD_ATKBD? Am I supposed to compile the kernel to change this?

Some of the keyboard's key doesn't work and some presses on its own.

If atkbd.reset=1 fails try initcall_blacklist=atkbd_init to disable the module from being initialized.

The linked patch moved atkbd from a module into the kernel - that's why blacklisting the module now fails.

Try disabling with a config file in /etc/sysctl.d example
EDIT: @loqs, I misunderstood Seth response #5, thank you.

WFV you linked to a thread discussing dmesg restriction,  how can you use a runtime setting to disable a module that is built in?

Tried atkbd.reset=1, but it doesn't work. However, initcall_blacklist=atkbd_init works wonder. My in-built keyboard is now disabled before X starts. Thank you! Marked as solved.
