[Alistair Cunningham]

On a laptop running Ubuntu 21.04 with Unity, if you:

1. Click on the bluetooth icon in the status bar.
2. Click on the enabled slider to disable bluetooth.
3. Suspend the machine.
4. Close the lid.
5. Wait ten seconds.
6. Open the lid.

then bluetooth is enabled again, even though it was disabled before suspending.

This still happens after upgrading to Ubuntu 21.10.

I've just realised that I've filed this bug against blueman, but I no longer have the blueman package installed, so it can't be the cause. The bluetooth related packages I have installed are:

# dpkg -l | grep blue
rc blueman 2.1.4-1 amd64 Graphical bluetooth manager
ii bluetooth 5.60-0ubuntu2 all Bluetooth support (metapackage)
ii bluez 5.60-0ubuntu2 amd64 Bluetooth tools and daemons
ii bluez-cups 5.60-0ubuntu2 amd64 Bluetooth printer driver for CUPS
ii bluez-obexd 5.60-0ubuntu2 amd64 bluez obex daemon
ii gir1.2-gnomebluetooth-1.0:amd64 3.34.5-3 amd64 Introspection data for GnomeBluetooth
ii gnome-bluetooth 3.34.5-3 amd64 GNOME Bluetooth tools
ii indicator-bluetooth 0.0.6+17.10.20170605-0ubuntu3 amd64 System bluetooth indicator.
ii libbluetooth3:amd64 5.60-0ubuntu2 amd64 Library to use the BlueZ Linux Bluetooth stack
ii libgnome-bluetooth13:amd64 3.34.5-3 amd64 GNOME Bluetooth tools - support library
ii pulseaudio-module-bluetooth 1:15.0+dfsg1-1ubuntu2 amd64 Bluetooth module for PulseAudio sound server

Does anyone know which package is likely to be the cause of this problem?
