; Sample Redshift configuration file ; Global settings for redshift [redshift] ; Set the day and night screen temperatures (in Kelvin) temp-day=5700 temp-night=3500 ; 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. You can specify a time range like 6:00-7:45. ;dawn-time=6:00-7:45 ;dusk-time=18:35-20:15 ; Set the screen brightness. Default is 1.0. ;brightness=0.9 ; It is also possible to use different settings for day and night ;brightness-day=0.7 ;brightness-night=0.4 ; Set the screen gamma (for all colors, or each color channel individually) ; Single value applies to all RGB channels gamma=0.8 ; Or specify R:G:B separately ;gamma=0.8:0.7:0.8 ; This can also be set individually for day and night ;gamma-day=0.8:0.7:0.8 ;gamma-night=0.6 ; Set the location-provider: 'geoclue2', 'manual' ; The location provider settings are in a different section. location-provider=manual ; Set the adjustment-method: 'randr', 'dummy' ; 'randr' is the preferred method for X11 ; The adjustment method settings are in a different section. adjustment-method=randr ; Configuration of the location-provider: ; Keep in mind that longitudes west of Greenwich (e.g. the Americas) ; are negative numbers. [manual] lat=48.1 lon=11.6 ; Configuration of the adjustment-method ; 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.
