On systems with UEFI Secure Boot enabled, recent Linux kernels will only load signed modules, so it's about time DKMS grew the capability to sign modules it's building.

These scripts are extended and scriptified variants of https://computerlinguist.org/make-dkms-sign-kernel-modules-for-secure-boot-on-ubuntu-1604.html and https://askubuntu.com/questions/760671/could-not-load-vboxdrv-after-upgrade-to-ubuntu-16-04-and-i-want-to-keep-secur/768310#768310 and add some error checking, a passphrase around your signing key, and support for compressed modules.

dkms-sign-module is a wrapper for the more generic sign-modules which can also be used outside of DKMS.

Installation

Create a directory under /root, say /root/module-signing, put the three scripts below in there and make them executable: chmod u+x one-time-setup sign-modules dkms-sign-module

Keyboard Backlight for boot menu & login screen

Enable keyboard backlight for boot menu & login screen on ASUS ROG Zephyrus G14 (should also work with other laptops with some adjustments). Tested with Fedora 39 on ASUS ROG Zephyrus G14 GA402RK.

Boot Menu

To enable the keyboard backlight for the boot menu, keyboard backlight needs to be turned on on shutdown. This can be accomplished by placing a executable into /usr/lib/systemd/system-shutdown/ (see https://www.freedesktop.org/software/systemd/man/latest/systemd-halt.service.html).
