i have an acer aspire vn7-791 laptop
linux mint 17
windows 8.1
all works fine, ive actually had it for almost 2 years dual booting Windows (which i only kept for a few games on steam), the only problem ive had so far is Bluetooth.
ive been able to use pretty much everything with the occasional head bump but, Bluetooth seems impossible to workout.

at first i was under the impression that the laptop was fairly recent and that the driver support from Acer was not available yet.
i cant seem to find nothing regarding that. its been 2 years, id hope some driver has made its way out..

recently i did an update on MINT with the driver manager and it installed a propietary driver for my NVIDIA graphics card, this i did not have that drive before, i was wondering if i may be missing something similar for the bluetooth. however i cant find something that may do the trick.

ive tried installing Blue devil
i tried several things actually, but im willing to try them all over again, if only someone could be patient enough and willing to help me out id be very grateful.

If you hope to resolve this, you need to suppl some information. So far, you have told us nothing, other than your bluetooth adapter doesn't work.

I had a look at Acer's web site, for your model. There are two bluetooth adapter drivers listed, one for an Intel adapter, and one for a Broadcom adapter.

Which adapter do you have? Open a terminal in linux, and run the command 'sudo lspci' copy and paste the results here. If this adapter is connected to the pci bus, then we have a chance of helping. If it is a USB adapter you plug in, tell us the make and model.

While you are in the terminal, also run the command 'sudo lsmod | grep blue' copy and paste the results here. That will tell us if you have any of the stuff loaded to talk to a blue tooth adapter.

You bluetooth adapter should be supported by the ath9k driver. See this link:

http://www.linuxwireless.org/en/user...orted_chipsets

Post the output of 'sudo lsmod | grep blue' and 'sudo lsmod | grep ath9k'.

btw thanks for your quick response man... really appreciate it

It appears you have the correct driver installed.

Have you got Blueman device manager installed? BTW, does bluetooth work under Win8?

1 members found this post helpful.

yes i do have that installed, bluetooth manager, bluedevil and devices adapters. those are the options that display when i type bluetooth .
the btmanager has the option to add devices greyed out.

i tried Bluetooth on my M$ Windows and it does work, so its a software issue for sure... heeelp please

Is bluetoothd running?

Run the command 'ps aux | grep bouetoothd' and post the results.

You had a mis-pronunciation in your finger tips. That should be 'bluetoothd'.

sorry for that haha

It has been a while since I added a bluetooth device. The Add button on my system is greyed out as well.

There should be a search button, looks like a magnifying glass. That should work. You need to make the device visible, then search it from the manager. You are looking for the 'mac' address of the device.

How far can you get with that process?
