Hello , I am using a dual boot setup on my laptop with amd cpu and nvidia graphics , the brightness control was working until recently but out of the blue today , it is just stuck at the maximum value.
The Output for ls sys/class/backlight is : nvidia_wmi_ec_backlight
I have tried using envycontrol , tried changing acpi_backlight as told in arch wiki but to no avail.
If anyone knows how i can seem to fix this issue please do help me.
