The error message makes this quite clear: "A handler is already registered for /org/freedesktop/UPower/devices/battery_hid_00o12oa1o68oa3o1b_battery"
So this seems to happen if you have a wireless mouse or keyboard, which powers down due to inactivity, and then gets repowered and it tries to register the same battery again. ** Summary changed: - upowerd crashed with signal 5 in dbus_g_connection_register_g_object() + abort with wireless HID devices: A handler is already registered for ** Summary changed: - abort with wireless HID devices: A handler is already registered for + abort with wireless HID devices: A handler is already registered for <battery> ** Changed in: upower (Ubuntu) Status: Confirmed => Triaged ** Changed in: upower (Ubuntu) Importance: Medium => High -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to upower in Ubuntu. https://bugs.launchpad.net/bugs/1112907 Title: abort with wireless HID devices: A handler is already registered for <battery> Status in Upower: Unknown Status in “upower” package in Ubuntu: Triaged Bug description: .
