安裝
安裝 redshift包 包。或者安裝 redshift-minimalAUR 包(最小依賴版本)。
前端
redshift-gtk 命令 來自 redshift包 包 提供托盤圖標用於控制 Redshift。 請參閱可選的依賴。
另外,也可以使用這些前端 redshiftgui-binAUR (GTK) 和 redshift-qtAUR, redshiftconfAUR 或者 和 plasma5-applets-redshift-control-gitAUR (Qt)。
使用
Redshift 需要你的位置才能開始運行 (除非使用 -O
選項),即需要你所在位置的經緯度。Redshift 使用一些程序獲得你的位置。如果這些程序不工作 (比如這些程序都沒有安裝), 你需要手動輸入你的位置。
快速開始
以基本的設置啟動:
$ redshift -l LATITUDE:LONGITUDE
LATITUDE 為所在位置的維度 , LONGITUDE 為所在位置的經度。
立即更改屏幕色溫:
$ redshift -P -O TEMPERATURE
TEMPERATURE 為期望的色溫值 (介於 1000
和 25000
之間)。
自動啟動
有幾個選項可以自動啟動Redshif:
- 滑鼠右鍵點擊托盤圖標選擇 Autostart 當 redshift-gtk 或者 plasma5-applets-redshift-control 已經啟動的時候。
- 放置 Redshift Desktop entry 在
~/.config/autostart/
或通過添加redshift
到你的窗口管理器或者桌面環境的 Autostarting 方法中。 - 使用 Systemd/User。 軟體提供了兩個 srvices:
redshift.service
和redshift-gtk.service
。激活哪一個服務取決於你是否想要顯示系統托盤圖表。
- 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
andInitialization of randr failed
.
配置
Redshift 會讀取配置文件 ~/.config/redshift/redshift.conf
[2] (如果該文件存在的話)。 然而,Redshift 不會自動創建這個文件, 因此你可能需要手動創建它。配置文件示例:redshift.conf.sample。
Automatic location based on GeoClue2
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.
- 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
orredshift
user service.
~/.i3/config
... exec --no-startup-id /usr/lib/geoclue-2.0/demos/agent ...
Automatic location based on GPS
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
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
疑難解答
Screen 1 could not be found
修改配置文件 "redshift.conf" 將 "screen 1" 改為 "screen 0"。
點擊托盤圖表不工作
安裝 libappindicator-gtk3包。 請看 redshift issue 363 and FS#49971.
Redshift 讓屏幕在設置的色溫值和默認的色溫值之間快速閃爍
確認沒有多個Redshift實例在同時運行。
Redshift 使用命令啟動時可以工作 但是以 systemd service 啟動失敗
systemd unit 有一行在 redshift.service
文件中,要求必須在display-manager.service
unit 被一個顯示管理器 display manager 啟動後才能啟動。 如果你不使用顯示管理器, 編輯 redshift.service
用戶服務文件刪除 After=display-manager.service
行. 運行 systemctl --user daemon-reload
後服務應該會正確初始化。
Redshift temporarily resets using some wine apps that reset gamma values
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
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
