bluetooth problem in ubuntu 12.04

**adityashah30** · January 14th, 2014

Hi guys,
I recently installed windows 8.1 along with ubuntu 12.04 lts on my dell xps l502x machine. Since, the installation of windows 8.1, the control switch for bluetooth which was same for wifi doesn't work. I mean that now with Fn+F2, I can only toggle wifi and bluetooth always remains on. Also, after waking from suspend, bluetooth always turns on. Please can anyone give me a solution to fix this?

Thanks

We may try rfkill command to toggle it on/off.

Please try -

Code:

rfkill block bluetooth

If that doesn't help disabling it, please post back the output of -

Code:

rfkill list

PS:
Have you tried "blueman" yet? It gives better control over bluetooth adapter, and some controls that the default applet doesn't show.

Does any of the suggestions I gave in my previous post works for you? If not, please post the same output as I asked for in that post. Much better - post the details along with the outputs in a separate thread of your own in "Apple Users" section of the forums and give us its link here.

It didn't work. Thats the output:

0: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no
1: brcmwl-0: Wireless LAN
Soft blocked: no
Hard blocked: no
2: hci0: Bluetooth
Soft blocked: no
Hard blocked: no

I tried the same with the sudo command before the rfkill, then the bluetooth was disabled. But when I open the bluetooth properties (right click) the button is on. So I typed "rfkill list" to check, and again bluetooth is on (soft blocked: no).

The only way for me to disable it was to click on the bluetooth icon (on top right corner) and select bluetooth, and the icon disappears with bluetooth disabled.

I found another thread that explains that this command has to be saved in a text file to be remembered at boot up. I might try this and will post a thread if it works. there are other similar problems like the screen brightness is always full per default at startup...

I tried blueman and it did give me much better control over bluetooth, but still not the exact thing i was looking for. My question is that why doesn't Fn+F2 control bluetooth anymore?

Hi,

I had the same problem. I blacklisted "acer_wmi" in /etc/modprobe.d/blacklist.conf. Next I added "ath3k" to /etc/modules. Now everything works again.
