Your suggestion didn't help. Bluetooth is still crashing when the keyboard is connecting, either from the keyboard itself or through bluetoothctl. To be on the safe side, I paired the keyboard again and restarted Ubuntu, but it still won't connect again after a connection loss:
$ bluetoothctl paired-devices Device 34:88:5D:42:7E:03 Keyboard K380 Device FA:6A:9E:DA:2B:30 M585/M590 $ bluetoothctl connect 34:88:5D:42:7E:03 Attempting to connect to 34:88:5D:42:7E:03 Failed to connect: org.bluez.Error.Failed It seems that my mouse is now nearly instantly connecting though, but no guarantees on that. I really can't explain why this is happening :( Repairing the keyboard after each lost connection isn't an option, especially because I always have to type the confirmation code on the keyboard, while pairing. Didn't you spot something unusual in my debug info? From my layman's view, there seem to be a lot of error messages. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1787571 Title: Bluetooth keyboard won't connect again after connection was lost To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bluez/+bug/1787571/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
