I use KDE 4.6.3 on an HP 8710w laptop. When I turn off the bluetooth adapter from the menu of the bluedevil system tray application, rfkill still lists the adapter as enabled (and so does blueman, which is running in parallel):

Code: Select all

$ rfkill list
0: phy0: Wireless LAN
        Soft blocked: no
        Hard blocked: no
1: hp-wifi: Wireless LAN
        Soft blocked: no
        Hard blocked: no
3: hp-bluetooth: Bluetooth
        Soft blocked: no
        Hard blocked: no
6: hci0: Bluetooth
        Soft blocked: no
        Hard blocked: no

If I turn off the adapter from blueman, the system tray icon disappears and bluedevil says there is no bluetooth adapter. This is only partially true - partially, because rfkill does not list the hci0 interface:

Code: Select all

$ rfkill list
0: phy0: Wireless LAN
        Soft blocked: no
        Hard blocked: no
1: hp-wifi: Wireless LAN
        Soft blocked: no
        Hard blocked: no
3: hp-bluetooth: Bluetooth
        Soft blocked: yes
        Hard blocked: no

I found this bug: Kdebluetooth does not start unless there is an active bluetooth adapter, but I think the problem is more general and I suspect Solid does not provide the necessary functionality. I'm trying to raise awareness of the issue so that eventually a bug is created (and hopefully, fixed in 4.7).

P.S. sorry for the double post - it was accidentally
