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 Kernel Packages, which is subscribed to bluez in Ubuntu. https://bugs.launchpad.net/bugs/1801642 Title: Bluetooth mouse sleep after 5 seconds of inactivity Status in bluez package in Ubuntu: Invalid Bug description: I'm having bluetooth mouse lag issue. After leaving it stationary for 5 seconds, I have to move it for 2 seconds before the pointer starts moving. I recently upgraded to Cosmic 3 days ago (from Bionic). There was no issue in the first 3 days, including after suspend/restart/shutdown. This issue only appears starting today. I tried: 1. Running 'bluetoothctl' and then 'scan off'. The command failed to run with 'Failed to stop discovery: org.bluez.Error.Failed'. 2. modprobe -r btusb, then modprobe it again. 3. sudo sh -c 'echo N > /sys/module/drm_kms_helper/parameters/poll' 4.
