用法

Adjust the color temperature of a screen according to its surroundings. Note: Redshift does not support Wayland. More information: https://manned.org/redshift.

• 根据配置文件 ~/.config/redshift.conf 调整屏幕色温

  redshift -P

  如果不加 -P 参数，每次使用 RedShift 的效果会叠加，导致显示的色调可能极端得冷或暖。-P 参数可以清除上次使用 RedShift 的效果。
• Turn on Redshift with a specific temperature during day (e.g., 5700K) and at night (e.g., 3600K):

  redshift -t 5700:3600

• Turn on Redshift with a manually specified custom location:

  redshift -l latitude:longitude

• Turn on Redshift with a specific screen brightness during the day (e.g, 70%) and at night (e.g., 40%): redshift -b 0.7:0.4
• Turn on Redshift with custom gamma levels (between 0 and 1):

  redshift -g red:green:blue

• Purge existing temperature changes and set a constant unchanging color temperature in one-shot mode:

  redshift -PO temperature

配置

~/.config/redshift.conf 文件：

[redshift]
temp-day=5500               # 白天色温
temp-night=3500             # 夜晚色温
location-provider=manual    # 手动配置位置

[manual]
lat=32                      # 纬度
lon=118                     # 经度

开机自启动

我尝试做成用户级服务，但总是不生效，于是在桌面环境（Cinnamon）的设置中将 RedShift 添加到开机自启动，本质上就是在 ~/.config/autostart/ 目录下添加了 redshift.desktop 文件，内容如下：

[Desktop Entry]
Type=Application
Exec=/usr/bin/redshift -P
Hidden=false
Name[zh_CN]=RedShift
Name=RedShift
Comment[zh_CN]=护眼夜灯
