; 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.
