On kernel 6.6 I have device /sys/class/backlight/intel_backlight
which allows system to adjust display brightness. but on 6.12 there is no such device. (6.12.63-1-MANJARO)

how can i set brightness level whith newer kernel? where is backlight device now?

It is the same for Linux 6.12 which is at 6.12.64-1 on stable branch.
