OLED linux screen control.
Firstly, here is the bible https://wiki.archlinux.org/index.php/backlight.
This repository contain a script wrapper for the gammastep package (redshift fork).
Install the package gammastep (AUR-available for archlinux).
Install the content of gammastep-wrapper/etc in usr/local/etc/ and gammastep-wrapper/bin in usr/local/bin.
You can also modify the path in the script.
The etc directory contain static and dynamic config that you should modify for your personnal usage.
OLED_BACKLIGHT_CORRECTION_STEP = inc/dec the backlight by this number OLED_BACKLIGHT_CORRECTION_GPS = latitude:longitude (networking is disabled -> use this) OLED_BACKLIGHT_CORRECTION_BACKLIGHT_MAX = maximum backlight allowed OLED_BACKLIGHT_CORRECTION_BACKLIGHT_MIN = minimum backlight allowed
gammastep-wrapper (+|-|=(0|[1-9][0-9]?|100))
+ increase OLED_BACKLIGHT_CORRECTION_BACKLIGHT by OLED_BACKLIGHT_CORRECTION_STEP and apply to the screen.
- decrease OLED_BACKLIGHT_CORRECTION_BACKLIGHT by OLED_BACKLIGHT_CORRECTION_STEP and apply to the screen.
=$PERCENT set backlight to $PERCENT and apply to the screen. $PERCENT must be between the maximum and minimum defined in the config.
You must wait 5 seconds between screen modification because of gammastep.
Feel free to fork, use, improve.
