I can’t change system brightness in fedora 41, it’s working fine in windows. I can change the slider/ keys are working fine, it shows brightness is reducing/increasing, but there’s no visual change in brightness.
System Information:
OS: Fedora Linux 41 (Workstation Edition) x86_64
Machine: ASUS TUF Gaming A15
Kernel: Linux 6.13.10-200.fc41.x86_64
DE: GNOME 47.5
WM: Mutter (Wayland)
CPU: AMD Ryzen 7 7435HS
GPU: NVIDIA GeForce RTX 2050
Also ls /sys/class/backlight shows acpi_video0
Try the program light to change brightness.
sudo dnf install light
man light
Hey @theprogram, I tried light, it changes the brightness value in
/sys/class/backlight/acpi_video0/brightness, also the change is visible in gnome brightness slider, but there’s no visual change in the screen brightness.
There have been a couple other Asus TUF brightness threads on the forums. I can’t look them up now, see if you can find them, I’ll check again tomorrow.
I tried almost all of them, nothing’s working for me. So, thought of posting it here.
any update @theprogram
If you can change the value in /acpi_video0 then maybe somehow your system is not responding to that config.
There are at least two other options for brightness configs, including intel_backlight.
Maybe you can change settings in the other configs to adjust brightness?? I have no idea how you would integrate that with Gnome if it does work.
