battery-graph shows empty graphs.
Cause: the battery-log on my system looks like this:
No power supply found
1549454931 94.23 1 2019/02/06 13:08:51 -
No power supply found
1549454991 94.57 1 2019/02/06 13:09:51 -
This is because the power adapter in /sys/class/power_supply is called slightly different from what battery-stat-collector excpects:
$ ls /sys/class/power_supply
AC0 BAT0
And the relevant section from /usr/sbin/battery-stats-collector :
if [ -f /sys/class/power_supply/AC/online ]; then
aconline=$(cat /sys/class/power_supply/AC/online)
elif [ -f /sys/class/power_supply/ACAD/online ]; then
aconline=$(cat /sys/class/power_supply/ACAD/online)
elif [ -f /sys/class/power_supply/ADP1/online ]; then
aconline=$(cat /sys/class/power_supply/ADP1/online)
else
echo "No power supply found"
fi
Just removing the else and echo statements at least makes the 'No power supply found' warning messages to go away from the log, and battery-graph works again.
Another fix would be to add AC0 to the tested directories, for example by replacing all of the tests above by:
for d in /sys/class/power_supply/{AC,AD}*/online; do
if test -f $d; then
aconline=$(cat $d)
echo $d;
break;
fi;
done
