Ok, after another waking from suspend, the issue comes back again. powertop shows "Bluetooth device interface status" is good. I can't identify which entry is the mouse, but the only bad USB devices are the keyboard and touchscreen.
Installing powertop somehow resolve this issue (for now). I'll check again tomorrow. I'll close this report if no issue in a week. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1801642 Title: Bluetooth mouse sleep after 5 seconds of inactivity To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bluez/+bug/1801642/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
