[SOLVED] Numlock not activating during boot time (systemd-boot)

My disk is encrypted with LUKS and I'd like to activate numlock automatically, since I type the digits inside my password normally with the numpad.
I've followed the wiki-article, on how to enable the numlock during early bootup using mkinitcpio: https://wiki.archlinux.org/title/Activa … _on_bootup

The AUR-package has been installed the normal way (git clone, makepkg -si, etc.) (no aur-helper or something else has been used) and added the HOOK-Tag inside the /etc/mkinicpio.conf file.
After that, I rebuilded the image using mkinitcpio -p linux. The numlock hook gets recognised, so I though It would work as intended.

Here's the HOOK-variable, for everyone who's interested:

HOOKS=(base systemd autodetect keyboard sd-vconsole numlock modconf kms block sd-encrypt filesystems)

I'm using systemd-boot and a UKI on my device.

When I restart the device, the hook doesn't work. I boot into the OS and then the numlock key isn't turned on.
Now my question is: Is there something off about the PKG, not working with LUKS and/or UKI or am I doing something completely wrong?

Because as I read through the wiki the hooks get executed from left to right.
And since the numlock hook is set to be executed before sd-encrypt, I don't know why the numlock key hasn't been turned on.
However, when I execute the command, that's inside the hook-file under /usr/lib/initcpio/hooks/numlock, it works as intended.

Re: [SOLVED] Numlock not activating during boot time (systemd-boot)

Your initramfs is using systemd-init and custom mkinitcpio hooks are intended for busybox-init .

In case you can't switch to a busybox-init, you will need a systemd service that runs before cryptsetup and sets numlock on .

There is https://aur.archlinux.org/packages/syst … lockontty/ but that looks like it will start too late in the boot process.

https://bbs.archlinux.org/viewtopic.php?id=248836 is about a similar issue, read it thoroughly.

Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.

clean chroot building not flexible enough ?
Try clean chroot manager by graysky

Sorry for the late answer.
I've been ill for the whole last week and couldn't do anything during that time.

But now coming back to the topic:
That did the trick.
I now made a mkinitcpio HOOK with a systemd-service, that get's executed before sd-encrypt.

Thank you very much.

Hi, would you mind sharing your solution please? I'm currently trying to achieve something somewhat similar.

Hope it's not necrobumping, the topic is barely the months old :-)

Thanks!

Hi @otaj

Sure, here ya go:
https://paste.gg/p/anonymous/4d4e479c7b … 0733faf111

Beware, it has been optimized for usage in combination with sd-encrypt.
Make sure to add the numlock hook BEFORE sd-encrypt (if you're even using it) in your mkinicpio.conf and regenerate the initramfs.

For most of our devices, it has been running quite a while without problems.

Alternatively, can we add instructions to the Arch wiki?

I'm not a fan of necrobumping my old, solved posts, but the link is working for me.
What I can do however is this:

/usr/bin/numlock:

#!/bin/bash
for tty in /dev/tty[0-9]; do
    /usr/bin/setleds -D +num < "$tty"
done

/usr/lib/initcpio/install/numlock:

#!/bin/bash
build() {
    add_binary /bin/bash
    add_binary /usr/bin/setleds
    add_binary /usr/bin/numlock
 
    cat >"$BUILDROOT/usr/lib/systemd/system/numlock.service" <<EOF
[Unit]
Description=Numlock before LUKS
Before=cryptsetup-pre.target
DefaultDependencies=no
[Service]
Type=oneshot
RemainAfterExit=yes
ExecStart=/usr/bin/numlock
EOF
    add_systemd_unit cryptsetup-pre.target
    cd "$BUILDROOT/usr/lib/systemd/system/sysinit.target.wants" || exit
    ln -sf /usr/lib/systemd/system/cryptsetup-pre.target cryptsetup-pre.target
    ln -sf /usr/lib/systemd/system/numlock.service numlock.service
}
 
help() {
    cat <<HELPEOF
This hook adds support to enable numlock before sd-encrypt hook is run.
HELPEOF
}
