redshiftでUbuntuスクリーンの温度調整、ブルーライトカット

Last updated at Posted at 2018-09-30

Ubuntuでのスクリーン温度調整にはredshiftというツールが使える(AmazonのサービスRedshiftとは関係ない)
コマンドラインから簡単に温度調整ができる
今回想定している環境はUbuntu16.04

インストール

$ sudo apt-get install redshift

温度指定

手動指定 (1000K~25000K)

$ redshift -O 5500

自動指定 (5500K)

$ redshift -o

値が低いほど赤に、高いほど青に近くなる(公式では3500~5500をデフォルトとしている)

温度リセット

$ redshift -x

redshiftが解除される。
