+; Global settings for redshift
+[redshift]
+; Set the day and night screen temperatures
+; my old default: temp-day=5700
+temp-day=5700
+temp-night=3700
+
+; Disable the smooth fade between temperatures when Redshift starts and stops.
+; 0 will cause an immediate change between screen temperatures.
+; 1 will gradually apply the new screen temperature over a couple of seconds.
+fade=1
+
+; Solar elevation thresholds.
+; By default, Redshift will use the current elevation of the sun to determine
+; whether it is daytime, night or in transition (dawn/dusk). When the sun is
+; above the degrees specified with elevation-high it is considered daytime and
+; below elevation-low it is considered night.
+;elevation-high=3
+;elevation-low=-6
+
+; Custom dawn/dusk intervals.
+; Instead of using the solar elevation, the time intervals of dawn and dusk
+; can be specified manually. The times must be specified as HH:MM in 24-hour
+; format.
+dawn-time=7:00-8:00
+dusk-time=22:00-23:45
+
+; Set the screen brightness. Default is 1.0.
+;brightness=0.9
+; It is also possible to use different settings for day and night
+; since version 1.8.
+;brightness-day=0.7
+;brightness-night=0.4
+; Set the screen gamma (for all colors, or each color channel
+; individually)
+;gamma=0.8
+;gamma=0.8:0.7:0.8
+; This can also be set individually for day and night since
+; version 1.10.
+;gamma-day=0.8:0.7:0.8
+;gamma-night=0.6
+
+; Set the location-provider: 'geoclue2', '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=wayland
+
+; Configuration of the location-provider:
+; type 'redshift -l PROVIDER:help' to see the settings.
+; ex: 'redshift -l manual:help'
+; Keep in mind that longitudes west of Greenwich (e.g. the Americas)
+; are negative numbers.
+[manual]
+lat=52.52
+lon=13.40
+
+; 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 only screen 0.
+; Note that the numbering starts from 0, so this is actually the first screen.
+; If this option is not specified, Redshift will try to adjust _all_ screens.
