Redshift for arch linux (red eyes)

aplikasi untuk mata agar tidak terkena cahaya biru, baik digunakan saat malam hari agar mata tidak mudah sakit. berikut cara installnya.

$ sudo pacman -S redshift

then how to use it?

save this config file at ‘~/config/redshift.conf’

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

; 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.

; 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: 'geoclue', '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 screen 1.
; Note that the numbering starts from 0, so this is actually the
; second screen. If this option is not specified, Redshift will try
; to adjust _all_ screens.

then use it

$ redshift

oke done.
