如何在 Redshift 上设置特定温度？

Question

我刚刚切换到 Ubuntu，在 Windows 上我使用的是 f.lux。我能够将温度设置为特定时间并保持不变，它根本不会改变。

现在我安装了 Redshift，我不能再这样做了。请问有人可以帮忙吗？

Answer 1

您可以从命令行永久设置色温：
打开 ( gnome-) terminal，键入命令：

redshift -O <temperature>

并按下 Return

要将其设置为（例如）3700：

redshift -O 3700

重置为“中性”：

redshift -x

有关更多（命令行）选项，请参见：

man redshift

（鉴于已安装 Redshift :)）

Answer 2

如果您使用redshift-gtk那么@Jacob 的方法将不起作用。

您需要在您的$HOME/.config目录中创建一个配置文件来更改它的设置。其官方页面中描述的示例配置文件创建，引用如下：

配置文件

可以创建配置文件，但文档有点少。您必须手动创建它并将其放在 ~/.config/redshift.conf 中。下面是一个配置文件的例子：

; Global settings for redshift
[redshift]
; Set the day and night screen temperatures
temp-day=5700
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
; 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

另一个示例配置也可以在Ubuntu 文档中找到。
