Title:
[HP ProBook 4540s] Qualcomm Atheros bluetooth properly works with
Ubuntu 16.04 LiveUSB but not on a fresh install
Status in linux package in Ubuntu:
Incomplete
Bug description:
I've tested my notebook with Ubuntu 16.04/17.04 (64-bit) LiveUSB pen
drive and the mini-pci Qualcomm Atheros QCWB335 [168c:0036] properly
works, both wifi and bluetooth.
After a fresh install from the same LiveUSB pen drive, the bluetooth
does not work.
$ bluetooth
bluetooth = none (no device)
Pressing the WiFi button turns off WiFi, and does not enable
bluetooth. Pressing it again turns WiFi on, but bluetooth remains off.
WORKAROUND: Suspend, and unsuspend the laptop.
