Fresh install of Manjaro and my bluetooth mouse and keyboard do connect on the login screen, but it can take 30+ seconds. I’ve got a Logitech M720 mouse and a Logitech K850 keyboard and both or either will struggle to connect once I get to the login screen - very occasionally I’ll get lucky and they’ll both just connect instantly. I did not have this problem on an old Ubuntu install.
What I see:
- Boot computer (reboot or boot from off, doesn’t matter)
- On login screen bluetooth icon will flicker on/off while indicator on mouse or keyboard flashes to show that it is connecting.
- Connection will fail, flickering will stop for a second, then another attempt to connect will begin.
- 2 and 3 might repeat 4 or 5 times before a successful connection is made.
- Remaining device goes through the same process to eventually pair.
Any suggestions for how to diagnose/fix would be appreciated. Thanks!
(Possibly related, the mouse will occasionally become quite laggy. I’ve tried reducing the conn_min_latency to 6 to fix this, but no result.)
Edit
Realised that I also encounter the same bahaviour when logged in if I turn off the mouse or keyboard and turn back on. Occasionally the bluetooth will stop working altogether. When it’s working, systemctl status bluetooth.service gives

If it crashes I get the message

I can then restart with
sudo rfkill unblock bluetooth
sudo systemctl restart bluetooth
After restarting the bluetooth I’ve also run into this output from systemctl status bluetooth.service

which can be fixed by restarting again.
Any thoughts?
