[SOLVED]Nvidia backlight setting

Hello.
My laptop is an ASUS ROG G752-VY. I ran Pacman -Syyu and after restarting, my qtile config broke. I noticed the culprit was qtiles backlight widget, so i commented it out.
I also noticed my backlight hotkey (Fn + (F3 or F4) wasn't working.
Upon further troubleshooting, i noticed that the nvidia_0 directory was missing from /sys/class/backlight.
Both my qtile backlight widget and my backlight acpi hotkey are bound to /sys/class/backlight/nvidia_0. The only dirs left there are acpi_video0 and acpi_video1, i also checked /var/log/pacman.log and saw that the nvidia driver was updated during the last update before restarting. How do i get my backlight settings back?

Re: [SOLVED]Nvidia backlight setting

I had the same issue with /sys/class/backlight/ entries disappearing, but I got it to work by using the ACPI flag

acpi_backlight=native

with nvidia-460.32.03-1.
