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

; The location provider and adjustment method settings

@Mario-paul Feel free to share a link!

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!

Thanks! =)

Here is another config file:

[redshift]
temp-day=5800 
temp-night=3500
brightness-day=1
brightness-night=0.72
dawn-time=5:00-6:00
dusk-time=19:30-20:00
gamma=0.750:0.750:0.750
transition=1
adjustment-method=randr
location-provider=manual
[manual]
lat=%yourLocation%
lon=%yourLocation%

thx after many attempts it works eventually

Should be noted this gist is ancient at this point. Glad there is still useful info though.

bcomnes, thank you very much for your post here. It worked like a charm for me after I entered my proper lat and long info. Take care and thanks a million. THanks to you, I will sleep better tonight having been shielded from the short wavelength light this evening! Cheers! Pete.
