কখনও কখনও আমি আমার ল্যাপটপের এইচডিএমআই পোর্টের সাথে সংযুক্ত আমার টিভিতে ভিএলসি মিডিয়া দেখতে পছন্দ করি এবং এখন আমাকে এটি করতে হবে:
কারণ আমি টিভি দেখার সময় অন্ধকারে বসে থাকতে পছন্দ করি!
স্ক্রিপ্টের মাধ্যমে কি কেউ ইতিমধ্যে তাদের জন্য সমাধান করেছেন ?
টিভি সবসময় এবং HDMI সংযুক্ত এবং ভিজিএ পোর্ট সবসময় মনিটর যদি জিনিষ সহজ করে তোলে।
উত্তর:
আমি এমন একটি স্ক্রিপ্ট তৈরি করেছি যা তৃতীয় মনিটরে আপনি মুভিটি দেখার সময় কীবোর্ড বা মাউস নিষ্ক্রিয়তার 5 মিনিটের পরে আস্তে আস্তে দুটি মনিটরকে ডিমে করে দেয়। আপনি যখন নিজের মাউসটি সরান বা আপনার কীবোর্ড ব্যবহার করেন তখন দুটো ম্লান নজরদারিগুলি দ্রুত আলোকিত হয় (তবে হঠাৎ আপনাকে ধাক্কা দেওয়ার জন্য নয়)।
আপনি ভাবার আগে আমি অনেক বেশি টিভি নোট দেখি এটি একটি ল্যাপটপ এবং প্রোগ্রামটি বহু দিন ধরে চলছে এবং ল্যাপটপটি স্থগিত / কমপক্ষে দিনে দু'বার পুনরায় শুরু হয়।
যেমন আপনার পাথ একটি ফাইল করার জন্য নিচের স্ক্রিপ্ট সংরক্ষণ করুন /usr/local/bin/movie.shঅথবা /home/your_user_name/bin/movie.shএবং তারপর ব্যবহার করুন:

sudo apt install xprintidleতারপরে স্ক্রিপ্টটি ব্যবহার করতে:

# 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
