如何在Ubuntu伙伴22.04中使红移更红？

Question

我正在使用Ubuntu伙伴22.04。到了晚上，红移会使色温达到4500 K。

如何进一步降低色温？与GNOME/KDE中的夜光特性不同，Redshift没有任何简单的方法来手动更改颜色温度(但是可以通过编辑redshift.conf来配置它，这就是我问这个问题的原因)。

展开(或提供与重复员额中的答案相比较的对比)。下面是我的~/.config/redshift.conf文件中的内容：

; Global settings for redshift
[redshift]
; Set the day and night screen temperatures
temp-day=3400
temp-night=3400

; 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
; This can also be set individually for day and night since
; version 1.10.
;gamma-day=0.8:0.7:0.8
;gamma-night=0.6

; Set the location-provider: 'geoclue', 'geoclue2', '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'
; Keep in mind that longitudes west of Greenwich (e.g. the Americas)
; are negative numbers.
[manual]
lat=48.1
lon=11.6

; 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.
; [randr]
; screen=1

除了：

[redshift]
temp-day=3400
temp-night=3400
transition=1
location-provider=manual
[manual]
lat=48.1
lon=11.6

我将temp-day和temp-night设置为3400。您可以相应地调整这些。

transition=1对我来说可能不是必要的，因为我的昼夜设置为相同的值，但您可能会对此感兴趣。

location-provider=manual是一种重要的方法，因为自动方法通常失败，红移将无法启动。

• 如果您的昼夜设置为不同的温度，您应该确定您的纬度(lat)和经度(lon)，并相应地设置它们。
• 当然，如果白天和夜晚设置为相同的温度，您可以将它们放在默认坐标(41.8和11.6)上。
