In my case this happens, when the bluetooth hardware wasn't initialized by kernel, e.g. it was toggled off by hardware switch (maybe software off might work as well). In such case /sys/class/bluetooth is not created, which prevents the bluetooth.service to start:
systemctl status bluetooth ● bluetooth.service - Bluetooth service Loaded: loaded (/lib/systemd/system/bluetooth.service; enabled; vendor preset: enabled) Active: inactive (dead) Condition: start condition failed at So 2016-02-14 12:37:00 CET; 4s ago ConditionPathIsDirectory=/sys/class/bluetooth was not met This means that bluetoothd is not running and thus does not provide the org.bluez dbus service, which in turn is what blueman is complaining about. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1533206 Title: Blueman-applet crash on login: DBusException in call_blocking(): org.freedesktop.DBus.Error.TimedOut: Failed to activate service 'org.bluez': timed out To manage notifications about this bug go to: https://bugs.launchpad.net/blueman/+bug/1533206/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
