Redshift Config - Difficult to adjust

Hello,

These are my system specs;

ASUS G75VW ROG Laptop
Slacwkare 14.1 x86_64
Openbox 3.5.2
xorg-server-1.14.3
nvidia-driver-340.24
GPU - GTX 660m

I"ve been playing around with the example configuration file found on the website, every setting I've tried, it's like turning down the brightness around 20%-25% if I want redshift to give me more of the temp color change, which makes the screen appear less blue.

I can certainly make the screen brighter, but then it seems to defeat the purpose of having it for this temp color change, so It seems very hard to slightly decress the brightness to only around 10% on my hardware and still give me this temp color change effect.

Any combination of settings I change I don't see working properly on my hardware. I would hope to make only a 10% decrease in brightness in the day or night as example, and still retain this a nice slight color temp change as well.

I'm assuming for the brightness 1.0 is the highest you can go?

; Global settings for redshift
[redshift]
; Set the day and night screen temperatures
temp-day=5700
temp-night=3500

; Enable/Disable a smooth transition between day and night
; 0 will cause a direct change from day to night screen temperature. 
; 1 will gradually increase or decrease the screen temperature
transition=1

; Set the screen brightness. Default is 1.0
;brightness=1.0
; It is also possible to use different settings for day and night since version 1.8.
brightness-day=1.0
brightness-night=0.9
; Set the screen gamma (for all colors, or each color channel individually)
gamma=0.8
;gamma=0.8:0.7:0.8

; Set the location-provider: 'geoclue', 'gnome-clock', 'manual'
; type 'redshift -l list' to see possible values
; The location provider settings are in a different section.
location-provider=manual

; Set the adjustment-method: 'randr', 'vidmode'
; type 'redshift -m list' to see all possible values
; 'randr' is the preferred method, 'vidmode' is an older API
; but works in some cases when 'randr' does not.
; The adjustment method settings are in a different section.
adjustment-method=randr

; Configuration of the location-provider:
; type 'redshift -l PROVIDER:help' to see the settings
; ex: 'redshift -l manual:help'
[manual]
lat=51.48
lon=0.45

; Configuration of the adjustment-method
; type 'redshift -m METHOD:help' to see the settings
; ex: 'redshift -m randr:help'
; In this example, randr is configured to adjust screen 1. 
; Note that the numbering starts from 0, so this is actually the second screen.
[randr]
screen=0

If you want higher brightness than 100 % you can take a look at #29.

I don't really understand what you are trying to do.

I'm only trying to adjust the brightness levels with;

brightness-day=1.0
brightness-night=0.9

But the changes seem extreme, just moving only 0.1 to .0.2, in these small increments actually makes the brightness change quite a bit.

So as example, going from brightness-day=1.0 to brightness-day=0.9 looks like around a 5% - 10% change for only moving .0.1... This is what I mean by extreme, I thought only moving at an increment of 0.1 should only change the screen like a few percentages at a time, not as much as 10%...

[maandree]

0,1 = 10 %, so your estimation of a change of 10 % make since,
if it does this in a transition everything is correct.

If you only want for example 5 % dimmer during the night you
should use

brightness-day=1.0
brightness-night=0.95

Ahhh ok, didn't know if it was extreme or not....

Ahh I see use 5, as 0.95... :)

thanks
