Eu tenho um Lenovo Thinkpad T530 com Ubuntu 17.10: meu mouse bluetooth tem um pequeno atraso inicial depois de não ser movido por alguns segundos.
Este é o log quando eu conecto o dongle:

Você tem algum truque?
Eu tentei a abordagem /etc/bluetooth/input.conf , definindo IdleTimeout como zero, mas isso não funciona para mim.
