Redshift is a very cool program that can help in keeping your eyesight healthy --- it'll tint your screen red a little bit when the night approaches.
This puts less strain in your eyes.
The problem
Everything was working good, I had the redshift package installed
and had setup it to start automatically on my ~/.i3/config.
It was just after an update that I started to see this when trying to run it:
Trying location provider `geoclue2'...
Using provider `geoclue2'.
Using method `randr'.
Waiting for initial location to become available...
Unable to start GeoClue client:
GDBus.Error:org.freedesktop.DBus.Error.NoReply:
Message recipient disconnected from message bus without replying.
Unable to get location from provider.
It never worked after that, even with the newest versions for geoclue2 and redshift:
pacman -Q geoclue2 redshift
geoclue2 2.5.1-1
redshift 1.12-2
The solution
After doing some sleuthing, I found a solution.
Edit your /etc/geoclue/geoclue.conf file, and add this at the end:
# ...
[redshift]
allowed=true
system=false
users=
To start Redshift automatically, add these lines to your ~/.i3/config:
exec --no-startup-id /usr/lib/geoclue-2.0/demos/agent
exec --no-startup-id redshift-gtk
That's it!
