The Problem

This kernel modules stops working after Resume from hibernation

Things that help

If you restart the service using the systemctl restart turbo-fan it starts working again.

Things I did to fix it

I dont know about other distros but Debian 13 has a way to store scripts that are executed before and after hibernation. I created the following script that restarts the service and that fixes this.

Location : /usr/lib/systemd/system-sleep/keyboard-rgb-fix.sh

#!/bin/sh


case $1 in
    post)
        # This runs *after* resuming
        /usr/bin/systemctl restart turbo-fan
        ;;
esac

sudo chmod +x /usr/lib/systemd/system-sleep/keyboard-rgb-fix.sh

As a result it start working as expected. I dont know if this fix is distro agnostic but its seems to work fine in my system ( age old statement 🥲 )
