Bug ID: 395990
Summary: Bluetooth controller unavailable most of the time
Product: frameworks-bluez-qt
Version: unspecified
Platform: Other
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: general
Assignee: now...@gmail.com
Reporter: tobias.kuen...@protonmail.com
Target Milestone: ---
I run KDE Neon 5.13.2 and have problems with my bluetooth adapter.
The adapter is detected only sometimes. I cannot make out any pattern. It
sometimes works after a cold boot, sometimes doesn't. It is unavailable most of
the time after waking from suspend.
`bluetoothctl list` shows nothing. If the adapter *is* detected, it shows
obviously shows up. In the KDE bluetooth adapter settings window the message
"no adapter has been found" is displayed.
```
rfkill list
0: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no
