monitorando a bateria na tora
Bom, o plugin monitor de bateria pro XFCE não está funcionando com o Linux 2.26.4, de forma que eu precisei dar um jeito de monitorar a bateria. Eu tinha visto em algum lugar que o Jeito Certo e portável de se monitorar (e usar) hardware era usando HAL, então decidi fazer um hack pra resolver meu problema por hora. Dei uma futucada nos comandos disponíveis e saiu isso:
#!/bin/sh
##################################################
# CUSTOMIZE HERE AS YOU WISH
##################################################
power_supply_alert(){
aplay /usr/share/orage/sounds/Spo.wav
}
##################################################
# YOU SHOULDN'T NEED TO CHANGE ANYTHING BELOW HERE
##################################################
# battery
BATTERY_DEVICE=$(hal-find-by-property --key info.category --string battery | head -n 1)
BATTERY_PERCENT=$(hal-get-property --udi ${BATTERY_DEVICE} --key battery.charge_level.percentage)
# AC Adapter
AC_DEVICE=$(hal-find-by-property --key info.category --string ac_adapter | head -n 1)
AC_STATUS=$(hal-get-property --udi ${AC_DEVICE} --key ac_adapter.present | sed -e 's/true/on-line/; s/false/off-line/')
if [[ ${BATTERY_PERCENT} -lt 10 ]] && [[ ${AC_STATUS} == 'off-line' ]]; then
power_supply_alert
fi
echo "AC: ${AC_STATUS} BAT: ${BATTERY_PERCENT}%"
Daí estou usando esse script com o "monitor genérico" do XFCE, que você configura com um comando e uma periodicidade, e ele mostra no painel a saída padrão do comando.
