How to manage systemd-boot?

Hello there!

I am trying to add a kernel parameter in systemd-boot. I want to add “acpi_backlight=native” parameter so that i can control my screen brightness.

I added the line in /etc/sdboot-manage.conf. Also in /etc/kernel/cmdline but had no luck.

In EndeavourOS i added the line in /etc/kernel/cmdline and then type “sudo reinstall-kernels” command but it seems it’s not available on cachyOS. What should i do? I am so confused


This is handled by our systemd-boot-manager. You can find the config in /etc/sdboot-manage.conf

There you put into the LINUX_OPTIONS array the variable you want to add and run “sudo sdboot-manage gen”
