nvidia_wmi_ec_backlight -> ../../devices/pci0000:00/PNP0C14:00/wmi_bus/wmi_bus-PNP0C14:00/603E9613-EF25-4338-A3D0-C46177516DB7/backlight/nvidia_wmi_ec_backlight

The brightness control works until i suspend the system (systemctl suspend). After resuming from suspend, brightness is at 100% , and cant be controlled in any way. I tried lts kernel and different kernel and driver versions, never worked. Brightness control always breaks after resume.

System Information:
Razer Blade 18 2023
kernel:6.15.4-arch2-1
nvidia-open: 575.64-5
window manager: niri (wayland)

I discovered this problem happens with suspend-to-ram (deep). Running systemctl suspend with s2idle, is not reproducing the error. But in order to turn my fans off, i need to use deep sleep mode.
