This is absolutely ridiculous! Which moron made the decision to leave BT *on* by default?

I thought Linux was designed by intelligent people...

run this:
sudo echo "options rfkill master_switch_mode=0" > /etc/modprobe.d/rfkill.conf

this returns a: bash: /etc/modprobe.d/rfkill.conf: Permission denied

How to do it?

Thanks,

That command will run echo with root privileges and the redirect will have normal user privileges hence the message you got. For it to work correctly you need to use tee

echo "options rfkill master_switch_mode=0" | sudo tee /etc/modprobe.d/rfkill.conf

Setting “options rfkill master_switch_mode=0” in /etc/modprobe.d/rfkill.conf did not fix this on HP Mini 5101; the only thing that did was to execute “rfkill block bluetooth” in /etc/rc.local.

(That HP Mini is still running Lucid.)

I was telling you how to correctly run the command the previous poster gave to update rfkill.conf ....

I think the command does work, if you only boot into terminal mode. I think the problem is when X starts along with all the other programs which ignore the current status of the bluetooth radio turning it on. When the command is run in rc.local, that is one of the last things that's run on startup and thus turns it off. So bluetooth is loaded as Off -> On -> Off via rc.local, not great I know. It would be good if it remembered the previous setting as it does under Windows. FYI, hciconfig hci0 down does the same thing I think. That's one of my main irritations having Bluetooth turned on at startup when it's not needed - I'd rather it was just left off when the module was loaded.

In 10.10 the command "rfkill block bluetooth" seems to work.

I second that, unfortunately Ubuntu desktops (both KDE and Gnome) have been painstakingly designed to be as idiot-friendly as possible, giving way to errors such as this one...

Just set this up on 11.10 x64 works a treat - simple is often then best
