Redshift

鼠标右键点击托盘图标选择 Autostart 当 redshift-gtk 或者 plasma5-applets-redshift-control 已经启动的时候。
放置 Redshift Desktop entry 在 ~/.config/autostart/ 或通过添加 redshift 到你的窗口管理器或者桌面环境的 Autostarting 方法中。
使用 Systemd/User。软件提供了两个 srvices: redshift.service 和 redshift-gtk.service。激活哪一个服务取决于你是否想要显示系统托盘图表。

注意：

The Redshift service files contain Restart=always so they will restart infinitely. See systemd.service(5).
When using a systemd user service, Xorg must be started before execution of the service, which is not the case without a Display manager. Otherwise you will get RANDR Query Version' returned error -1 and Initialization of randr failed.

配置[编辑 | 编辑源代码]

Redshift 会读取配置文件 ~/.config/redshift/redshift.conf [2] （如果该文件存在的话）。然而，Redshift 不会自动创建这个文件, 因此你可能需要手动创建它。配置文件示例：redshift.conf.sample。

Automatic location based on GeoClue2[编辑 | 编辑源代码]

In order to allow access Redshift to use GeoClue2, add the following lines to /etc/geoclue/geoclue.conf:

/etc/geoclue/geoclue.conf

[redshift]
allowed=true
system=false
users=

Restart redshift.service and/or any other Redshift instance to apply the changes.

注意：

This workaround is not needed with Geoclue2 version 2.5.0 and above.
If using GNOME, also toggle Location Services to "On" in Settings > Privacy.
Due possible bugs with geoclue2 and Redshift [3], it may be required to use the manual location-provider instead, e.g. for Paris:

~/.config/redshift/redshift.conf

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

...

; Keep in mind that longitudes west of Greenwich (e.g. the Americas)
; are negative numbers.
[manual]
lat=48.853
lon=2.349

If using i3wm or similar, you will also need to enable the geoclue agent on startup. As well as systemctl --user enable redshift-gtk or redshift user service.

~/.i3/config

...
exec --no-startup-id /usr/lib/geoclue-2.0/demos/agent
...

Automatic location based on GPS[编辑 | 编辑源代码]

You can also use gpsd^包 to automatically determine your GPS location and use it as an input for Redshift. Create the following script and pass $lat and $lon to redshift -l $lat;$lon:

#!/bin/bash
date
#gpsdata=$( gpspipe -w -n 10 |   grep -m 1 lon )
gpsdata=$( gpspipe -w | grep -m 1 TPV )
lat=$( echo "$gpsdata"  | jsawk 'return this.lat' )
lon=$( echo "$gpsdata"  | jsawk 'return this.lon' )
alt=$( echo "$gpsdata"  | jsawk 'return this.alt' )
dt=$( echo "$gpsdata" | jsawk 'return this.time' )
echo "$dt"
echo "You are here: $lat, $lon at $alt"

For more information, see this forums thread.

Use real screen brightness[编辑 | 编辑源代码]

Redshift has a brightness adjustment setting, but it does not work the way most people might expect. In fact it is a fake brightness adjustment obtained by manipulating the gamma ramps, which means that it does not reduce the backlight of the screen. [4]

Changing screen backlight is possible with redshift hooks and xorg-xrandr^包 and xorg-xbacklight^包 but, please see Backlight#xbacklight as there are some limitations and you may have to find another method of controlling the backlight depending on your hardware.

You need to create a file in ~/.config/redshift/hooks and make it executable. You can use and edit the following example:

$ mkdir -p ~/.config/redshift/hooks

Create and adjust the following script:

~/.config/redshift/hooks/brightness.sh

#!/bin/sh

# Set brightness via xbrightness when redshift status changes

# Set brightness values for each status.
# Range from 1 to 100 is valid
brightness_day=100
brightness_transition=50
brightness_night=10
# Set fade time for changes to one minute
fade_time=60000

if [ "$1" = period-changed ]; then
	case $3 in
		night)
			xbacklight -set $brightness_night -time $fade_time
			;;
		transition)
			xbacklight -set $brightness_transition -time $fade_time
			;;
		daytime)
			xbacklight -set $brightness_day -time $fade_time
			;;
	esac
fi

Make it executable:

$ chmod +x ~/.config/redshift/hooks/brightness.sh

Restart the redshift.service to apply changes.

Check the service status as it should not contain the following message:

redshift[..]: No outputs have backlight property

疑难解答[编辑 | 编辑源代码]

Screen 1 could not be found[编辑 | 编辑源代码]

修改配置文件 "redshift.conf" 将 "screen 1" 改为 "screen 0"。

点击托盘图表不工作[编辑 | 编辑源代码]

安装 libappindicator-gtk3^包。请看 redshift issue 363 and FS#49971.

Redshift 让屏幕在设置的色温值和默认的色温值之间快速闪烁[编辑 | 编辑源代码]

确认没有多个Redshift实例在同时运行。

Redshift 使用命令启动时可以工作但是以 systemd service 启动失败[编辑 | 编辑源代码]

systemd unit 有一行在 redshift.service 文件中，要求必须在display-manager.service unit 被一个显示管理器 display manager 启动后才能启动。如果你不使用显示管理器, 编辑 redshift.service 用户服务文件删除 After=display-manager.service 行. 运行 systemctl --user daemon-reload 后服务应该会正确初始化。

Redshift temporarily resets using some wine apps that reset gamma values[编辑 | 编辑源代码]

If you notice that using some wine apps, redshift seems to reset temporarily upon launch, or adjusting settings, or etc, then there is a useful registry key that seems to alleviate this. See [5] and [6]. Set or create the string value

HKEY_CURRENT_USER\Software\Wine\X11 Driver

UseXVidMode="N"

using the registry editor, or import/set it otherwise.

Redshift GDBus.Error:org.freedesktop.DBus.Error.AccessDenied on start[编辑 | 编辑源代码]

If running $ redshift and you are getting:

$ redshift

Trying location provider `geoclue2'...
Using provider `geoclue2'.
Unable to start GeoClue client: GDBus.Error:org.freedesktop.DBus.Error.AccessDenied: 'redshift' disallowed, no agent for UID 1000.
Unable to connect to GeoClue.
Unable to get location from provider.

or running $ redshift-gtk and getting the similar error:

$ redshift-gtk

Failed to run Redshift
Trying location provider `geoclue2'...
Unable to start GeoClue client:
GDBus.Error:org.freedesktop.DBus.Error.AccessDenied:
'redshift' disallowed, no agent for UID 1000.
Unable to connect to GeoClue.
Unable to get location from provider.

You can create a systemd unit file in ~/.config/systemd/user/geoclue-agent.service with the following config:

~/.config/systemd/user/geoclue-agent.service

[Unit]
Description=redshift needs to get a (geo)clue

[Service]
ExecStart=/usr/lib/geoclue-2.0/demos/agent

[Install]
WantedBy=default.target

Start and enable the service with systemctl: $ systemctl --user enable --now geoclue-agent.service and try running redshift again.

If you still get the same error, it may be because of geoclue being locked down to a few programs by default. Try adding the following lines to /etc/geoclue/geoclue.conf (see redshift issue 158 and FS#40360) and run $ redshift again:

/etc/geoclue/geoclue.conf

[redshift]
allowed=true
system=false
users=
