When I plug/unplug ac adapter, upower doesn't report that it's state changed, kde's power manager doesn't switch profiles. If I start with ac adapter plugged in and then unplug it, battery indicator shows that battery is discharging, but ac adapter is plugged in. Battery state is reported correctly. This problem exists in every linux distribution I tried for every kernel version from 2.6 to 3.4. Also it seems that this bug affects many people (open bugs in kde, upower bugtrackers). I found a workaround and I think I must share it. I rebuilt kernel with ACPI_PROCFS_POWER=y ("Deprecated power /proc/acpi directories") and noticed that if I do "cat /proc/acpi/ac_adapter/AC/state" then state of the adapter becomes correct in kde, upower's output, etc. I added a file to /etc/acpi/events/ with following contents: event=battery action=cat /proc/acpi/ac_adapter/AC/state > /dev/null After restarting acpid everything works. The only problem is that ACPI_PROCFS_POWER is deprecated. I hope this bug will be fixed before the option will be removed. And I think this workaround must be described somewhere in documentation/FAQ/wiki. _______________________________________________ power-management mailing list power-management(a)lists.fedoraproject.org https://admin.fedoraproject.org/mailman/listinfo/power-management
