画面色調整ソフト
ハード面の輝度調整はWindows時代から変わらないが,色の調整手段がない.探した.使えなかった.どれも扱えなかった.
xbacklight
変わらなかった.おや.
BUGがあるらしく初めに実行しないといけないらしい
xrandr --output LVDS --set BACKLIGHT_CONTROL native
Ubuntu ってどうなの?: 輝度の設定(xbacklight)
sudo apt-get install xbacklight libxxf86vm1
$ xrandr --output LVDS --set BACKLIGHT_CONTROL native warning: output LVDS not found; ignoring X Error of failed request: BadRROutput (invalid Output parameter) Major opcode of failed request: 140 (RANDR) Minor opcode of failed request: 15 (RRGetOutputProperty) Serial number of failed request: 31 Current serial number in output stream: 31
xbrightness-rgbgamma
あーこれこれ(スクリーンショットを見ながら),これが欲しかった.使えなかった.GUIを使えなかった.xbrightness-rgbgamma 10 を実行すると,画面が黒くなってどうにもならなかった.
sudo apt-get install gettext

Using this value will not change the color temperature of the display. Setting the color temperature to a value higher than this results in more blue light, and setting a lower value will result in more red light. Default values: Daytime temperature: 5500K Night temperature: 3700K Please report bugs to <https://bugs.launchpad.net/redshift>
