I realise= d=20 that my bluetooth controller was nowhere to be found. I thought running=20 hciconfig would bring it up, but all it did was to complain that there was = no=20 device found. rfkill would not list it either. Modprobing various modules did not produce a device, so searching for answe= rs=20 I thought of booting into MSWindows. After I enabled the device in MSWindo= ws=20 I rebooted into Linux and was surprised to see the bluetooth controller was= =20 visible again in lspci. How come that switching off the device in one OS, affects the other? :-/ 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= =20 would randomly never come up at boot and no amount of alsactl could wake it= =20 up. A swift reboot into MSWindows would reset audio and all would work fin= e=20 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=20 mentioning it just in case. =2D-=20 Regards, Mick --nextPart2469708.FzMBn4RTIJ Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQEcBAABCAAGBQJWY3PvAAoJELAdA+zwE4YeKhQH/15DFNyDK5lnKsS3FDC881oa m6/T7RHXL4fo1wii8im6YF5BBYYN/SsnetG9UiPGKu+1N+7SEPDFOu3xlpbn3/Lr LTygiKTSy2c0K0DFY2X8qZLXCpY9HYCumHEqahnBVqpJa8BDu5v6cmgT3VxfPGR0 Sai/gZGIzO2XabE1PT4NtXeTEpLoM5/mYPKn26vkN+y/K0KdwY+/Ozx15ORJo7x5 dq873t8M2z35BKBrdslGIhv6XaIAFdAzOLnIThuZFWOacWknWfW5uVu+8Cl8++Ss GsL6j7Sa/6f4FHLsHr8VB3P5PHAr9q1ljvPy2N29p23oRBmVc2cMFdChE2wZwPw= =8uan -----END PGP SIGNATURE----- --nextPart2469708.FzMBn4RTIJ--
