Obtenir l'état de la batterie pour mettre à jour plus souvent ou sur courant alternatif
Un problème gênant que j'ai est que l'upower prend quelques minutes ou plus pour mettre à jour l'état de ma batterie (ce problème est similaire à cet article mais je fournis les détails de mon ordinateur portable). Cela signifie que si je sors mon ordinateur portable de l'hibernation, il affiche un pourcentage de batterie incorrect pendant quelques minutes et lorsque je branche mon chargeur, l'icône de la batterie ne l'indique pas (bien que le voyant de charge du matériel s'allume). Autre que ces cas, le temps de mise à jour ne me dérange pas.
Curieusement, lorsque je débranche mon chargeur, l’icône se met immédiatement à jour. J'ai mis au point un solution temporaire à mettre à jour après le réveil qui peut ne pas fonctionner, mais il semble qu'il devrait y avoir une bonne solution. Exécuter Ubuntu 16.04 sur Acer Aspire E5-575G-53VG.
acpi indique toujours le pourcentage et l'état de la batterie corrects. Sudo service upower restart force la mise à jour de l'état de la batterie de l'upower.

Ce que j'ai remarqué, c'est que lorsque le chargeur est branché, l'état de la batterie est toujours discharging. Cependant, /org/freedesktop/UPower/devices/line_power_ACAD rapporte online correctement. Toute aide concernant ce problème est appréciée. Je ne me souviens pas d’avoir ce numéro sur KDE.
Alors que je travaillais sur l'un de mes projets précédents, j'ai découvert que l'indicateur de puissance sur Unity avait apparemment un délai de mise à jour lié à un événement. Il provient du démon UPower, qui semble être utilisé par l'indicateur pour obtenir des informations sur l'alimentation. Cela gêne les scripts personnalisés qui tentent de surveiller l'utilisation de la batterie via le démon UPower avec une certaine précision. Cependant, le service UPower a des appels pour mettre à jour/actualiser ces informations. Le script ci-dessous tire parti de cet appel dbus. Le script doit être copié et enregistré sous forme de fichier, de préférence dans le dossier ~/bin.
L'utilisation est très simple: ./update_battery.py <SECONDS>, où <SECONDS> correspond à la fréquence d'actualisation des informations. Évidemment, vous devez garder à l'esprit qu'un rafraîchissement très fréquent entraînera une utilisation accrue des ressources. Je recommanderais donc quelque chose de plus ou de moins judicieux, par exemple 3 à 10 secondes.

La réponse de Sergiy a fonctionné, mais cela me causait quelques problèmes de performances. Je l'ai modifié pour être plus efficace.
tout d'abord, j'ai modifié update-battery.py pour supprimer la boucle de sommeil:
#!/usr/bin/env python
# -*- coding: utf-8 -*-
import dbus
def run_dbus_method(bus_type, obj, path, interface, method, arg):
if bus_type == "session":
bus = dbus.SessionBus()
Elif bus_type == "system":
bus = dbus.SystemBus()
else:
return None
proxy = bus.get_object(obj, path)
dbus_method = proxy.get_dbus_method(method, interface)
return dbus_method(arg) if arg else dbus_method()
def find_battery_path():
call = ['system', 'org.freedesktop.UPower',
'/org/freedesktop/UPower', 'org.freedesktop.UPower',
'EnumerateDevices', None]
devices = run_dbus_method(*call)
for i in devices:
if 'BAT' in i:
return str(i)
return None
def main():
bat_path = find_battery_path()
call = ['system', 'org.freedesktop.UPower',
bat_path, 'org.freedesktop.UPower.Device',
'Refresh', None]
run_dbus_method(*call)
if __== '__main__':
main()
j'ai ensuite créé un script bash distinct qui appelle update-battery.py toutes les 5 secondes, mais uniquement lorsque cela est nécessaire. J'ai appelé cette mise à jour de la batterie et l'ajouté en tant que script de démarrage.
#!/bin/bash
#
# @version 1.0
# @script keep-battery-updated
# @description keeps the battery status updated
#
##
while sleep 5; do
badbattery=$(upower -i /org/freedesktop/UPower/devices/battery_BAT0 | grep state: | cut -d ':' -f 2 | xargs)
case $badbattery in
discharging)
badbattery="Discharging"
;;
charging)
badbattery="Charging"
;;

badbattery="Full"
;;
esac
goodbattery=$(acpi -V | grep Battery | sed -n 1p | cut -d ':' -f 2 | cut -d ',' -f 1 | xargs)
if [ $badbattery != $goodbattery ]; then
python3 /usr/local/bin/update-battery.py
fi
done
Désormais, la batterie est mise à jour toutes les 5 secondes, sans aucun problème de performances notable jusqu'à présent.
