This is a silly customization thing but it’s my desktop and I’ll do whatever I want. In Kubuntu (I guess is the same on ubuntu, don’t really know because unity is too complex to use for my mind) you have a bluetooth icon. I’ve never used bluetooth in my entire life (true story) so I want to remove it.
You can accomplish this easily disabling the device. Something like this:
$ sudo rfkill list bluetooth 1: sony-bluetooth: Bluetooth Soft blocked: no Hard blocked: no $ sudo rfkill block 1
Obviously you must change the ’1′ from the second command accordingly of the output from the first command. You could get bluetooth back executing rfkill unblock.
