Right, troubleshooting bluetooth, my favorite... not.
I am moving from a Thinkpad X260 to a Thinkpad T450 because of the bigger screen. I am using a Thinkpad Bluetooth Laser Mouse.
On the X260 I run Manjaro Cinnamon and bluetooth works impeccably with this mouse. When I get back to the desktop from the lockscreen, suspend or boot I just need to wiggle my bluetooth mouse for a bit and it reconnects.
On the T450 I installed Manjaro Cinnamon fresh with Manjaro Architect. I see the following behavior:
- after lockscreen, suspend or boot the bluetooth mouse is not paired and will not automatically reconnect
- I have to manually push the pairing mode button on the mouse, open the bluetooth manager and re-pair the mouse. When this is done, the mouse works fine.
- after boot I see the bluetooth icon in the tray flicker a couple of times when I wiggle my mouse and if I put the pointer on the icon, I can see the mouse is connecting/disconnecting rapidly
- after maybe 30 seconds or so this connecting/disconnecting stops and it is no longer trying to connect to the mouse
What I have done so far:
- been up and down the Arch wiki, forums and googled a lot
- I have disabled bluetooth co-existence
- I have trusted the mouse in bluetoothctl after it was paired
- I have added the mouse-definition and a default pincode of 0000 to
- I have set AutoConnectTimeout=0 and AutoEnable=true in
That pretty much exhausted my bluetooth knowledge.
dmesg is showing a Bluetooth error: "Bluetooth: hci0: last event is not cmd complete (0x0f)". This is already being discussed on kernel.org and I can find some references to it in Ubuntu mailinglists and bugtracker, but it would appear that this bug does not cause any of the behavior I mentioned.
I'd be very happy if someone knows a trick to get my mouse working
