My configuration file for Redshift. Place it in ~/.config/ Drag redshift onto the Startup Applications menu to have it boot on start

redshift.conf

; Global settings
[redshift]
temp-day=6500K
temp-night=5000
transition=1
;gamma=0.8:0.7:0.8
gamma=1.000:1.000:1.000
location-provider=geoclue
;location-provider=manual

;brightness=1.0:0.5

; The location provider and adjustment method settings
; are in their own sections.

[manual]
lat=45.53068
lon=-122.68317

; In this example screen 1 is adjusted by vidmode. Note

Thanks for all the info everyone. This config is ancient but glad people have found the hints helpful

Thanks to this file I remembered github gists were a thing. Made one of my own with the updated redshift config file settings and now I can retrieve them for new installations/distro hopping. Thanks @bcomnes! also, like @zilvins said, 2700k is perfect at night. not too blue, not too yellow.

Sure! It works automatically using geoclue2, randr adjustment, and 5800k day 2700k night with smooth transition. Screen brightness and gamma adjustments are disabled but can be added by uncommenting the relevant settings. brightness has separate day and night options too as of a recent-ish redshift update.

enjoy!
