I came across a rather peculiar phenomenon today with my laptop. I realised |
2 |
that my bluetooth controller was nowhere to be found. I thought running |
3 |
hciconfig would bring it up, but all it did was to complain that there was no |
4 |
device found. rfkill would not list it either. |
5 |
|
6 |
Modprobing various modules did not produce a device, so searching for answers |
7 |
I thought of booting into MSWindows. After I enabled the device in MSWindows |
8 |
I rebooted into Linux and was surprised to see the bluetooth controller was |
9 |
visible again in lspci. |

11 |
How come that switching off the device in one OS, affects the other? :-/ |
12 |
|
13 |
What should I do next time to enable bluetooth from within Linux? |

PS. There's a parallel to this with the same laptop. Some years ago audio |
17 |
would randomly never come up at boot and no amount of alsactl could wake it |
18 |
up. A swift reboot into MSWindows would reset audio and all would work fine |
19 |
in Linux thereafter. Some cursory troubleshooting at the time didn't help me |
20 |
much. I don't expect that the two issues are related, but thought of |
21 |
mentioning it just in case. |
