[電腦] 用Redshift調整Linux系統的螢幕色溫

在Windows系統下我習慣用F.lux來對螢幕色溫進行調整，且它可以根據時區對色溫進行即時的變動。雖然F.lux也有Linux版本，但它能調整的選項不多，因此我後來就改用了Redshift。

如果您希望無論白天或晚上，Redshift都能維持基本的色溫值的話，可以透過下面的步驟實現。

$vi /home/[使用者名稱]/.config/redshift.conf
輸入以下內容

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

temp-day=3500
temp-night=3500

; 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
transition=1

; Set the screen brightness. Default is 1.0
;brightness=0.9
; It is also possible to use different settings for day and night since version 1.8.
;brightness-day=0.7
;brightness-night=0.4
; Set the screen gamma (for all colors, or each color channel individually)
gamma=0.8
;gamma=0.8:0.7:0.8

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

; 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.
adjustment-method=randr

; Configuration of the location-provider:
; type 'redshift -l PROVIDER:help' to see the settings
; ex: 'redshift -l manual:help'
[manual]
lat=40
lon=110

; 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.
[randr]
screen=0

修改紅色文字來設定您想要的日夜色溫，儲存之後重新啟動Redshift即可。
