Bluetooth not showing up after kernel update 3.3.6
So, bluetooth worked fine before I upgraded the kernel to 3.3.6 and now:
-I can't turn it on using the gui or the bluez interface.
-it does NOT have a keyboard button to turn it off/on.
-some infos from the console:
$ hcitool scan
Device is not available: No such device
$ hcitool dev
Devices:
$ hcitools -all
$ rfkill list
0: tpacpi_
Soft blocked: no
Hard blocked: no
1: tpacpi_wwan_sw: Wireless WAN
Soft blocked: no
Hard blocked: no
2: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no
$ hciconfig list
Can't get device info: No such device
so what seems to be the problem? Or is it a bug?

Then you are using a 3rd party kernel. I suggest you contact the developer and report the issue

Okay, I thought i did a regular kernel update, thanks for the answer! Do you have a quick link how I can get back to the default kernel?
oskar truffer (oskar-truffer) said : | #5 |
Okay, I just downgraded the kernel to the default ubuntu 3.3.2 release. Thanks!
Does it work under the default kernel?
oskar truffer (oskar-truffer) said : | #7 |
Yes it does. I had problems with a driver so the system froze completely, that's why i've upgraded the kernel to 3.3.6 in the first place, but it seems to be fixed by now in 3.3.2 as well. Is there a "default" 3.3.6 kernel for ubuntu?
Could try using Quantal, it uses the 3.5.X.X kernel
