I have been trying to enable my bluetooth of my laptop (Lenovo Ideapad-Y400), it comes with a Atheros bluetooth that has some problems with the kernel.
First of all I wasn't able to turn on my bluetooth, but I realized that runing sudo rfkill block bluetooth twice, and then run againt twice sudo rfkill unblock bluetooth, the bluetooth configuration menu was able to find devices and pair them but it crash after 1 minute, then the bluetooth is not able to find anything. Also, if I turn off the bluetooth in that particular case, I'm not able to turn it on again, I have to run again rfkill un/block to toggle it on.
Then, I tried the solution from here, and it worked like a charm, now I can turn on and off my bluetooth. Seems the version of my kernel had that problem, also I installed Ukuu, to install a newer kernel, but my graphics card crashes (right now I'm using the patched kernel to make my bluetooth work "Linux 4.15.0.39.48"). But now my bluetooth can't find any device. I tried running bluetoothctl, and I powered on it (power on), and make it discoverable (discoverable on), and also running scan on my computer is not able to find any device, same running hcitool. Same thing installing bluez.
Can you help me with this guys?
Thank you so much.
Here I'm adding some outputs that in some forums ask them to get the context of the system.
