Can't have the brightness controll on GNOME49

I was configuring a machine with Ultra9-275HX and 5090 Max-Q running Linux 6.18.5-200.fc43.x86_64 and GNOME Shell 49.2

$ inxi -Gxx

And I find out that this was a frequently mentioned topic so I first tried the most seen solution. I add a few startup param try to let the system use native for backlight controlling.

$ sudo cat /etc/default/grub 
GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR="$(sed 's, release .*$,,g' /etc/system-release)"
GRUB_DEFAULT=saved
GRUB_DISABLE_SUBMENU=true
GRUB_TERMINAL_OUTPUT="console"
GRUB_CMDLINE_LINUX="rhgb quiet rd.driver.blacklist=nouveau,nova_core modprobe.blacklist=nouveau,nova_core video.use_native_backlight=1 i915.enable_dpcd_backlight=1 acpi_backlight=native"
GRUB_DISABLE_RECOVERY="true"
GRUB_ENABLE_BLSCFG=true

But the solution is not working for me.

So then I tried brightnessctl and modifying backlight file directly.

$ sudo ls /sys/class/backlight/
intel_backlight  nvidia_0

But still didn’t make it, somehow the brightnessctl only works on nvidia_0(though still no brightness change) and also the backlight directories’ name is not quite the same to what I’ve seen in the topics.

Would it be a issue associated to the nvidia-driver or optimus ?
