La télécommande du téléviseur Sony suspend l'ordinateur portable via le contrôle réseau
tvpowered (La TV contrôle l'alimentation de l'ordinateur) est un bash script qui suspend automatiquement l'ordinateur portable lorsque la TV Sony Bravia est éteinte. En outre, il va :
- Éteignez l'image du téléviseur pour économiser de l'énergie lorsque vous ne regardez pas de films sur le téléviseur.
- Affiche une bulle contextuelle lorsque vous modifiez le volume du téléviseur utilisé pour écouter de la musique.
Veuillez noter que fonctionne uniquement avec les téléviseurs Sony Bravia .
Vue d'ensemble
Lorsque le téléviseur est éteint tvpowered suspend, met en veille prolongée ou éteint automatiquement l'ordinateur portable. Modifiez le paramètre de SCTL variable globale pour contrôler l'action à entreprendre.
tvpowered doit être exécuté en tant qu'utilisateur normal et appelé dans les applications de démarrage.
La conception du programme est simple :
- Attendez que le téléviseur soit sous tension.
- Commencer une opération entièrement active.
- Vérifiez si le téléviseur est éteint. Si elle est éteinte, passez à l'étape 5.
- Dormez pendant 3 secondes et répétez l'étape 3.
- Suspendre ou mettre hors tension le système lorsque le téléviseur est éteint.
- Si vous reprenez à partir d'une suspension, retournez à l'étape 1.
Entre ces étapes, des bulles d'information apparaissent sur le bureau et sont également enregistrées dans le journal de bord. journalctl :
$ journalctl -xe | grep tvpower

Résumé
J'ai été inspiré par la question de l'OP et je n'avais jamais réalisé à quel point mon processus de suspension de fin de journée était lourd et fastidieux :
- Trouvez l'endroit où se trouve le curseur sur l'un des trois moniteurs.
- Naviguez en haut à droite de n'importe quel moniteur et cliquez à gauche sur le menu Cog.
- Tirez la souris vers le bas pour suspendre l'option
- Cliquez sur suspendre (en faisant attention de ne pas cliquer sur arrêter à côté !).
- Éteindre le téléviseur Sony
- Éteindre le téléviseur Toshiba
tvpowered a éliminé les fastidieuses étapes 1. à 4.
Bonus - Tour de lumière derrière la télévision
Pour le visionnage de nuit, il y a une lumière derrière le téléviseur. Chaque fois que l'ordinateur portable se met en veille, il éteint d'abord la lumière.
Créer le script /etc/NetworkManager/dispatcher.d/pre-down.d/smartplug_off et le placer dedans :
#!/bin/bash
# NAME: smartplug_off
# PATH: /etc/NetworkManager/dispatcher.d/pre-down.d
# DESC: Turn off smartplug light power for TV light
# DATE: March 7, 2020.
# CALL: Called by Network Manager before going down. Network manager in turn
# is called by systemd during suspend/hibernate/shutdown
# NOTE: myisp.sh and hs100.sh must be installed for hs100 tp-link power plug.
# https://developer.gnome.org/NetworkManager/stable/NetworkManager.html
PlugName="192.168.0.15"
status=$(hs100.sh -i "$PlugName" check | cut -f2)
if [ $status == "OFF" ] ; then
: # Nothing to do already off
elif [ $status == "ON" ] ; then
hs100.sh -i "$PlugName" off
else
echo Error hs100.sh not responding check connection and IP "$PlugName".
fi
