err.still loading even already blacklisted it?

how about remove it since u dont use it?
nope i just want to disable it upon boot, not to permanently remove it.. so that i can reenable it whenever i want to use it.. and yes it still loaded even when i've blacklist its module
turns out that gnome bluetooth applet forced bluetooth module to start even when i've already blacklist it.lol
and i'm not the only one had this problem, heres bug report regarding this on launchpad
https://bugs.launchpad.net/ubuntu/+bug/306739btw i've solved it already
CODE
sudo apt-get remove gnome-bluetooth
CODE
sudo apt-get install blueman
CODE
sudo apt-get install bum
CODE
sudo bum
find bluetooth service and disable it(untick on box beside it) and click Apply..done and done
