Mac-like-automatic-brightness

A simple script to provide a "Mac" like automatic brightness adjustemnt/ animation.

Now as a system service

Run setup.sh to make it a service and automaticaly set your SensorToDisplacScale

made for the FrameWork laptop

based on 2017 MacBook Pro

read Configuration for detailed informatoion about what options you have to easily customize/ adjust the bightness or animation speed

Updating

Run git pull to download the latest version

Then run ./setup -u to update the the service and script running on your system with newly downloaded / modifyed versions

Requires

bc For running as your user you need to be part of the video group sudo usermod -a -G video $USER if your not apart of the group

If your installing as a system service your user dose not need to be apart of the group

Non 12th Gen Intel Framework Owners

Your sensor has a diffrent range thant the 12th Gen Intel Framework laptop sensors, please see chart bellow

       Type     |  Sensor Rnge | STDScale
 11th Gen Intel | 0 - 3207633  | 1
 12th Gen Intel | 0 - 3984     | 24
 Dell Insp 7359 | 0 - 15000    | 20 

Controls

./AutomaticBrightness.sh | Defualt running mode of script

./AutomaticBrightness.sh -i [NUMBER] | Increase the offset your brightness sensors raw reading

./AutomaticBrightness.sh -d [NUMBER] | Decrease the offset your brightness sensors raw reading

/dev/shm/AB.offset | Stores current offset for the sensor

• Changing the offset of your backlight while the service is running is one way you increase or decease your screen bightness but keep the automatic adjustments when the lighting changes

Configuring

Light Change The percent of light change needed to be seen by the sensor for it to change the screen brightness

SensorDelay Time in seconds the script will wait to check the sensor for a luminess change after the animation (LevelSteps * AnimationDelay)

SensorToDisplayScale The ratio from sensor to screen brighness, recommended minimum 24 for 12th gen framework laptops. Increasing the value will give a brighter screen for the amount of light in the room/ enviroment

LevelSteps Sets amount of brightness steps, recomended to match refeshrate

AnimationDelay Speed of the brightness animation(delay between each step), recomended screen refreshrate in seconds (0.16 of 60Hz)

MinimunBrightness The minimum screen brightness, recomended minumim 001 so the backlight dosn't turn off

Run setup.sh -u to update the installed script and service

~~ Other things to note but shouldn't have to adjust

Light The file where your lightsensor has its current value

CurrentBirghtness The file where your screen stores its current brightness

MaxScreenBrightness The highest value your screen supports, check /sys/class/backlight/intel_backlight/max_brightness on framework laptops
