Hello forums. I'm new to Linux and I love to learn.

I have a 7-year-old laptop/notebook and am a bit annoyed by the LED of the bluetooth (see attached image)constantly switched ON whenever i boot or login. I was able to tame it from autostarting in W7 before. Now that i completely switched to Linux i want to do the same. Maybe you can point me to the right directions and/or resources. Any suggestions and tips will be greatly appreciated. Thanks in advance.

GOAL1: Prevent Bluetooth from autostarting.
GOAL2: Manually activate Bluetooth.

DEVICE: Acer Aspire 4740
OS: Slackware32 14.2 stable; vmlinuz-generic-smp-4.4.14-smp; KDE

hahaha I just went through this myself but just not as much as you did to try and resolve it.

add your user to these groups to get bluetooth.
as far as all of that other stuff you did, you didn't need to do that, so I do not know if that will conflict with what you actually needed to do. provided your bluetooth is always plugged in like mine in my laptop.. anyways you can log in as root, startx and see if your bluetooth icon is showing up, that way you'll know it is working then add yourself to them groups, or not, just add yourself to them groups log out, log in, if that doesn't work reboot, if that doesn't work then fix what you did to your system prior to posting this help me request.

then you should be able to just turn it off with the gui interphase, or set it to not show present to anyone, as it is not hurting anything being on.

should shut it down completely. typing that in your terminal of course. :D

thanks for the reply BW-userx, but i think im not very clear with my initial post. What im trying to achieve is to prevent/stop my bluetooth from automatically loading. I will update my help me request asap. And by the way, i have:

Now that I am in Slack. I personally don't see why just doing what you did didn't work.

Just removing it from being an executable is suppose to stop it from auto starting at boot.

what exaclty do you mean by that? LED where on your hw or in you DE?

if it is on your hardware then that is a BIOS / BT power button on your laptop thing

Sir i am referring to this: http://i.imgur.com/tCCjPR1.jpg

Yep, that is your HW (Hardware) the OS (Operating System) has nothing to do with that.

You're BIOS (Basic Input/Output System), kind of does along with your MB (Mother Board, or MoBo).
Most laptops (Smaller desktops that can be carried along with you, and placed on your lap to use.) have a button on it to turn it on or off, some use the fn+ (some key) to turn it on or off, this has nothing to do with your OS per sa.
If you find that button, it might even be what that light is sitting in, that is a button yes, no?

have you tried pushing it to see if that light changes color?

Some laptops may not even provide you with a means to turn it on or off, the light is just their to let you know it is working in the since that the power to it is on.

I suggest you put your OS back the way it was, then all you have to do is Push that button, or key combination to turn your BT (BlueTooth) on or off. :D Cheers!

I like you're choice of title to indicate an annoying Bluetooth (situation) as opposed to wisdom tooth. Whatever word man came up with to indicate that whole thought process. Comparison, perhaps?

thanks again for bearing with me BW-userx, but Sir are you saying that it is impossible to prevent my HW from automatically switching ON? That there is no way to configure my OS to solve my problem?

If your laptop does not provide a means to cut power to it, short of you actually going in and cutting the wire, then it will always be on. The OS only sees it as a result of the power to it being on, then provides a means for you to use it. The only other way for you to not have it running so others will not see it. Is to keep it in hidden mode, or, I'd have to look this up, keeping your execute permissions on your rc.bluetooth so all you have to do is run the command to start / stop the daemon that controls the software that runs it. as oppose to having it start up on boot.

rc.bluetooth start / rc.bluetooth stop - to turn it on or off which is actually only switching the software that it uses "on" or "off".

Have you entered the BIOS editor at boot up and searched for something to disable Bluetooth?

As for disabling it from Linux, you can set the configuration to kill it the moment it starts: see section 3 of

Thank you for the links DavidMcCann i will try and digest it, and for the BIOS thing, i haven't hit my F2 button for a while now.

update
I cant find anything obvious in my BIOS setup utility with regards to disabling bluetooth.
I tried this (3. Disable Bluetooth on Gentoo / Slackware and other Linuces) from one of the links you provided earlier wherein i have to modify my /etc/rc.d/rc.local by adding

and
first Reboot = the LED still autoloads, so i reboot again
2nd Reboot = the LED still autoloads then switched OFF by itself (im using runlevel 3 by the way) so i thought it's VOILA but as soon as i logged in (not as root) and issued startx, there it goes again together with the system tray icon. So that's it, i believe it don't fully worked because i already mess it up. Do you think it's time to reinstall? TIA

No, but it might be time to admit that the manufacturer of the laptop has won. :banghead:

I don't know why you just don't put a piece of electrical tape over the LED so it quits bothering you.

You might be right Sir but i can feel there's a solution to this. Thanks again.

That would double if not triple the annoyance Sir. You are funny and we both know the saying "Laughter is ...medicine". Thanks again.

i thought i disabled the tray icon. wow!

lmao ~ find out how your distro adds your user to that bluetooth then remove that user and that will go away. because he/she will no longer have privs to use it.

then look, hopefully their is a group called bluetooth, just remove your user from that group, when you boot up agian, and log in, it will not be there.

here is how ya do that click me I dare ya.

or you could just take another piece of electrical tape and place it across your screen where that icon is at. ;)
