Feature Request: Real Backlight Control #30

Open BeatLink opened 3 years ago

BeatLink commented 3 years ago

As i understand it, redshift's brightness settings doesnt actually affect the backlight of the monitor but creates a fake brightness by manipulating the gamma settings. Is it possible to include an option that allows qredshift to manipulate the real backlight settings by using either xbacklight or acpilight?

Further resources on doing this can be found here: https://wiki.archlinux.org/index.php/Redshift#Use_real_screen_brightness

Alternatively, there are some other commandline tools that you could include in the hooks script. This article lists a few:

Hello, I personaly was pleased that it doesn't use the actual brightness settings. Because it allowed me to get less than 0% brightness in the night.

May i suggest middle way: make both ways possible and let each user decide weither to use the actual brightness or the artificial one.

Another way I've seen this seamlessly implemented:

0% - 100% = actual backlight control -∞ - 0% = software brightness filter
