Hello, I installed the manjaro system, but the screen brightness is stable and does not change. I tried this code, but the problem is not resolved

GRUB_CMDLINE_LINUX_DEFAULT=“quiet apparmor=1 security=apparmor resume=UUID=6f1352f1-5ab6-41a5-8c20-1b3267bf0ae6 udev.log_priority=3 i915.enable_dpcd_backlight=0”

sudo update-grub

Do you have the acpilight package installed?

Did add your user to the video group after installing acpilight package? (logoff and login)
