Description Iyán M. V. 2025-11-27 12:47:35 UTC

SUMMARY
Today I noticed the following weird issue. I disabled Bluetooth in the morning using the widget in the system tray. However, when I turned on my headset, they automatically connected to the laptop. They appear in the audio widget, but bluetooth is still shown as "disabled" even though the icon changed to the same icon as when a device is connected.

Clicking on the enable button correctly fixed the wrong state. I still could not find a way to reproduce the issue, but I will update the report if I figure it out. At the moment there must be a way to keep the bluetooth enabled while showing as disabled in the system tray.

Weird. When it's in the wrong state, can you paste the output of `bluetoothctl show | grep -i power`?

$ bluetoothctl show | grep -i power
        Powered: yes
        PowerState: on
        SupportedIncludes: tx-power
        SupportedCapabilities.MinTxPower: 0xffffffd8 (-40)
        SupportedCapabilities.MaxTxPower: 0x0008 (8)
        SupportedFeatures: CanSetTxPower

It happened again today. Also, since in between I enabled the option to show the number of connected devices. Now it correctly shows that one device is connected but opening the widget shows like it's disabled. I will attach a video.

Video showing weird state of bluetooth widget

To reach this state, I open the Bluetooth widget and turn it off there. Then I noticed that the headset connected to the laptop. The bluetooth widget is not shown directly in the main panel there because of the option "Only show when relevant", so when it's "off" it's only visible opening the status and notifications.
