Іноді мені подобається дивитись VLC-носії на телевізорі, підключеному до порту HDMI на ноутбуці, і мені зараз доводиться:
тому що я люблю сидіти в темряві під час перегляду телевізора!
Хтось вирішив вищезазначене вже для себе за допомогою сценарію?
Телевізор завжди підключений до HDMI, а монітор завжди до порту VGA, якщо це полегшує роботу.
Відповіді:
Я створив сценарій, який повільно затемнює два монітори через 5 хвилин бездіяльності клавіатури чи миші, поки ви дивитесь фільм на третьому моніторі. Під час переміщення миші або використання клавіатури два затемнені монітори швидко світлішають (але не раптом, щоб вас шокувати).
Перш ніж подумати, що я дивлюся занадто багато телевізійних записок, це ноутбук, і програма працює багато днів, і ноутбук призупиняється / поновлюється принаймні два рази на день.
Збережіть сценарій нижче до імені файлу на своєму шляху, наприклад, /usr/local/bin/movie.shабо /home/your_user_name/bin/movie.shвикористовуйте:
chmod a+x /path/to/script/movie.shПакет Xorg xprintidleнеобхідний для відстеження того, як довго ваш комп'ютер не працював з моменту руху миші або клавіатури:
sudo apt install xprintidleПотім для запуску сценарію використовуйте:
movie.shПримітка: При тестуванні, зміна TIME_TO_FADEвід 200000до , 10000так що ви тільки повинні чекати 10 секунд замість 200 секунд для в'янучої , щоб почати.
#!/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.
