How to remove bluetooth icon on [k]ubuntu?

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.

Kubuntu wiht ugly menus, buttons and weird look and feel?

This seems to be a popular problem in kde’s history, after an update your menus and general look & feel of your desktop is just weird (actually is just without any theme). Trying to set a theme again it won’t work. To fix this you just have to remove one file and regenerate the cache config with another command, just execute:

$ rm ~/.config/Trolltech.conf
$ kbuildsycoca4 --noincremental

Then restart your session (or close your apps and open them again) and there you go, pretty again!
