Can any one else confirm that directly changing via the command line is instant ? It certainly is for me eg.

$ cat /sys/class/backlight/intel_backlight/max_brightness
976
$ cat /sys/class/backlight/intel_backlight/brightness
123
$ echo 600 | sudo tee /sys/class/backlight/intel_backlight/brightness
600
$ echo 200 | sudo tee /sys/class/backlight/intel_backlight/brightness
