Redshift manually

Redshift does not work properly if you use mobile broadband, etc. One way is to use redshift manually.

1. Install redshift via package management

2. Make config file and a laucher for redshift

mkdir -p $HOME/.config/redshift

nano $HOME/.config/redshift/redshift.conf

In Mint 21 redshift.conf must place into $HOME/.config

nano $HOME/.config/redshift.conf

… the contents (for Puolanka and Kajaani)

; Global settings for redshift
; Set the day and night screen temperatures

; 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.

; 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.

; 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.

; Set the screen brightness. Default is 1.0.
; It is also possible to use different settings for day and night
; since version 1.8.
; Set the screen gamma (for all colors, or each color channel
; individually)
; This can also be set individually for day and night since
; version 1.10.

; Set the location-provider: 'geoclue2', 'manual'
; type 'redshift -l list' to see possible values.
; The location provider settings are in a different section.

; Set the adjustment-method: 'randr', 'vidmode'
; type 'redshift -m list' to see all possible values.
; 'randr' is the preferred method, 'vidmode' is an older API.
; but works in some cases when 'randr' does not.
; The adjustment method settings are in a different section.

; Configuration of the location-provider:
; type 'redshift -l PROVIDER:help' to see the settings.
; ex: 'redshift -l manual:help'
; Keep in mind that longitudes west of Greenwich (e.g. the Americas)
; are negative numbers.

; Configuration of the adjustment-method
; type 'redshift -m METHOD:help' to see the settings.
; ex: 'redshift -m randr:help'
; 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.

…. save and quit

Ctrl x

nano $HOME/.config/redshift/redshift

…. a contents

redshift -l 64.283:27.683332

… save, quit and make it executable

chmod +x $HOME/.config/redshift/redshift

3. Add redshift script to the startup applications or make a launcher from $HOME/.config/redshift/redshift

PS. You can find the right location from clock settings in Mate desktop, but replace commas using dot.

Redshift.conf with temp-day=5000 and temp-night=2700. redshift.conf
