Bluetooth switches on after restart

[Lars Falk-Petersen]

I never use bluetooth on my laptop, so there is no point for it to stay ON. It draws extra power, leaves my system vounrable to attacks, and allows me to be tracked (i.e. blueproximity).

When switching bluetooth off, it only stays off until the next time I reboot. Even if I use the bluetooth-button on my keyboard, which turns off the card entirely.

Is this reproducible with your system fully up to date?

I can't reproduce this on my own system. When bluetooth is turned off via the menu or via the killswitch (soft killswitch in my state, via Fn+F2 on a Dell system), bluetooth remains blocked. This is supposed to be taken care of by the rfkill-store/rfkill-restore upstart jobs; and probably needs a bit more investigation (and it would probably be useful for the kernel team to look at it).

Partly. When deactivating using the applet, it stays off. When deactivating via hardware button (Fn + F12), it's on again after boot. Seems to me like the hardware button is the most powersaving way of disabling, as there's a LED indicating the bluetooth status. This LED only turns off when using hardware button.

I uploaded the apport information.
