Linux Mint: Como evitar a suspensão enquanto a música está tocando

Question

Eu tenho um problema simples: gostaria que meu computador evitasse a suspensão quando a música está tocando em um aplicativo de desktop no meu computador - quero fazer melhor do que um script que mantém meu computador acordado sempre que um aplicativo de música estiver aberto . Estou executando o Linux Mint 18.

Eu imagino que poderia funcionar aplicativo por aplicativo, mas eu também me pergunto se há uma maneira de fazer isso, aproveitando o applet de som Cinnamon normal (ou similar). Esse applet é capaz de detectar e controlar a reprodução de qualquer aplicativo de música que o usuário tenha aberto - Spotify, Clementine, Banshee ou outros. Existe alguma maneira de um script determinar, a partir do applet de som ou de um aplicativo específico, se a música está tocando?

Estou ciente desta questão: de suspender enquanto toca música no Spotify , mas a resposta aceita não resolve o problema, e a cafeína mudou completamente desde então.

Meu comportamento desejado é benéfico por vários motivos:

• Se o usuário deixar um aplicativo de música aberto em segundo plano, mas com a reprodução interrompida, o computador não ficará acordado indefinidamente.
• Se o usuário deixar o computador com a reprodução de músicas, pretendendo que a música continue, eles não precisarão se preocupar em ter seu reprodutor de música em tela cheia para manter a música ativa.
• O usuário pode aproveitar esse comportamento de maneiras diferentes. Por exemplo, eles poderiam selecionar 20 minutos de música relaxante antes de dormir. Quando a lista de reprodução de 20 minutos terminar, o computador será suspenso durante a noite. A duração do sono se ajusta automaticamente ao tamanho da lista de reprodução.

Estou disposto a eliminar isso, mas nunca escrevi um roteiro para algo dessa natureza e não sei por onde começar. Isso parece tão básico, mas útil, que talvez devesse ser um pedido de recurso para o Mint.

Eu tenho lutado com a mesma coisa. Eu encontrei alguns outros posts que falaram sobre o uso de pactl para verificar o status do pulseaudio. Aqui está um link:

Eu tentei criar um script muito simples que irá alterar o tempo limite de suspensão nas configurações de energia do Cinnamon para nunca temporariamente enquanto a música estiver tocando e, em seguida, reverter quando a música parar. Esta é a minha primeira tentativa real em um script, então se você puder melhorar, fique à vontade. Provavelmente só funcionará em Canela.

#!/bin/sh

# Script to temporarily set Cinnamon's suspend timout for AC and battery to "Never"
# while audio is playing.  It then reverts the settings when audio is no longer detected.

# Create directory to store settings if it doesn't exist.
if [ ! -d ~/.config/audiocaffeine ]; then
    echo "Configuration directory not found!"
    echo "Creating ~/.config/audiocaffeine"
    mkdir ~/.config/audiocaffeine
fi

# Restore previous value for AC suspend timeout if script
# was interrupted.
if [ -f ~/.config/audiocaffeine/acsuspend ]; then
    echo "Restoring previous AC suspend timeout."
    read acsuspendtime < ~/.config/audiocaffeine/acsuspend
    gsettings set org.cinnamon.settings-daemon.plugins.power sleep-inactive-ac-timeout $acsuspendtime
    echo "Removing temporary file ~/.config/audiocaffeine/acsuspend"
    rm ~/.config/audiocaffeine/acsuspend
fi

# Restore previous value for battery suspend timeout if script
# was interrupted.
if [ -f ~/.config/audiocaffeine/battsuspend ]; then
    echo "Restoring previous battery suspend timeout."
    read battsuspendtime < ~/.config/audiocaffeine/battsuspend
    gsettings set org.cinnamon.settings-daemon.plugins.power sleep-inactive-battery-timeout $battsuspendtime

Answer 2

Eu fiz um pouco mais de trabalho no script acima e agora ele deve funcionar no Cinnamon, Mate e Ubuntu executando o Gnome. Eu experimentei as versões Live USB do Linux Mint 19 Cinnamon e Mate, assim como o Ubuntu 18.04 - Gnome. Espero que isso seja útil para algumas outras pessoas.
