Gestion de l'énergie¶
Utilisation de HAL¶
apt-get install hal hal-find-by-capability --capability ac_adapter hal-find-by-capability --capability battery
Et normalement ptbatterysystemtray devrait marcher ... mais nada
Utilisation du /sys¶
Développement d'une application "sur mesure" pour tester : horizon-tablet-battery
- /sys/class/power_supply/twl6030_battery/status
- /sys/class/power_supply/twl6030_battery/capacity
- /sys/class/power_supply/twl6030_battery/charge_full
- /sys/class/power_supply/twl6030_battery/charge_now

- /sys/class/power_supply/twl6030_battery/current_now
