I get them with a frequency of one disconnect every 30-60min. Before the upgrade this was not happening. The only way to restore the connection is to remove and re-insert the dongle. I've tried various models from different manufacturers from BT v2 up to v4 and all of them behave the same. I've tried to also to increase the default autosuspend from 2 to 30 echo "30" > /sys/module/usbcore/parameters/autosuspend and the frequency of the resets dropped but not disappear. I've tried with 0 to disable the autosuspend and it was more stable, however it drained the battery of the keyboard very quickly. --- ProblemType: Bug ApportVersion: 2.20.10-0ubuntu13.1 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC1: bnv 2347 F.... pulseaudio /dev/snd/controlC0: bnv 2347 F.... pulseaudio CurrentDesktop: XFCE DistroRelease: Ubuntu 18.10 HibernationDevice: RESUME=UUID=e962613c-fc88-4740-8f0a-997838d3c2cf InstallationDate: Installed on 2017-11-02 (382 days ago) InstallationMedia: Kubuntu 17.10 "Artful Aardvark" - Release amd64 (20171017.1) IwConfig: enp0s25 no wireless extensions. lo no wireless extensions.
