Having similar problem in 16.04 as well, though the reason might be different.
With everything enabled this is the output of rfkill: 2: phy0: Wireless LAN Soft blocked: no Hard blocked: no 5: Toshiba Bluetooth: Bluetooth Soft blocked: no Hard blocked: no 7: hci0: Bluetooth Soft blocked: no Hard blocked: no When either the switch in System Settings or the Indicator menu is turned Off Toshiba Bluetooth is soft blocked, hci0 disappears, and the Indicator icon disappears. When the System Settings switch is On, Toshiba Bluetooth unblocked, hci0 appears soft blocked, and the Indicator icon appears with it's menu switch Off. When the Indicator menu switch is On hci0 is unblocked. It appears that each switch is grabbing the earliest bluetooth radio to effect rather than just one. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1126108 Title: Indicator disappears entirely when disabling / turning off bluetooth To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/indicator-bluetooth/+bug/1126108/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
