TVでVLCメディアを視聴している間は、すべてのモニターをオフにします
回答:
3台目のモニターで映画を見ているときに、キーボードまたはマウスを5分間操作しないと、2台のモニターをゆっくりと暗くするスクリプトを作成しました。マウスを動かしたりキーボードを使用したりすると、2つの淡色表示のモニターがすぐに明るくなります（突然の衝撃ではありません）。
ステータス画面の例
私がテレビをたくさん見ると思う前に、これはラップトップであり、プログラムは何日も実行されており、ラップトップは少なくとも1日2回サスペンド/レジュームされています。
セットアップ手順
以下のスクリプトを、/usr/local/bin/movie.shまたはなどのパスのファイル名に保存して、次を/home/your_user_name/bin/movie.sh使用します。
chmod a+x /path/to/script/movie.shXorgのパッケージxprintidleは、マウスの動きやキーボードの操作からコンピューターがアイドル状態になっている時間を追跡するために必要です。
sudo apt install xprintidle次に、スクリプトを起動するには、次のコマンドを使用します。
movie.sh注：テストする場合は、TIME_TO_FADEから200000に変更して10000、フェードが開始するまで200秒ではなく10秒だけ待つ必要があります。
スクリプト
#!/bin/bash
# NAME: movie.sh
# PATH: ~/eyesome
# DESC: Dim monitors 1 and 3 after 5 minutes of activity
# DATE: June 27, 2019. Modified November 5, 2019.
# PARM: Pass any parameter 1 to generate trace output
# UPDT: 2019-07-05 Add dependancy message. Improve sleep calcualation.
# 2019-09-01 Display how long dimming lasted in hours, minutes, seconds
# 2019-09-07 Do not brighten if toggling play / pause of movie with
# mouse click or Enter key. Log first wake and if a second wake appears
# within 1 to 3 seconds then wake up. Otherwise forget first wake signal.
# 2019-11-05 Replace scrolling messages with Statistics display.
