It seems as I found a permanent fix. In case anyone having the same issue, this approach fixed it for me:
1. Unpair the mouse in Windows, i.e. delete it inside the Bluetooth settings. This will delete the respective keys in the Windows registry, too. 2. Unpair the mouse in Ubuntu, i.e. revoke the connection inside the settings menu. Thereafter, check whether the respective directory inside /var/lib/bluetooth/<XX:XX:XX:XX:XX:XX>/<Device> still exists and if so, delete it (requires root privileges). 3. Reboot Ubuntu. 4. Repair the mouse in Ubuntu, this will create a new directory inside /var/lib/bluetooth/<XX:XX:XX:XX:XX:XX>/. 5. Verify that the connection works after rebooting / restarting the Bluetooth service without any freezes. 6. Thereafter, start Windows and repair the mouse there, too. This of course will overwrite Ubuntu's setting, but the directory and the configuration files exists, only the keys will become invalid by the Windows pairing. 7. Verify that the mouse works fine in Windows, too, in particular after rebooting etc. 8. Restart Ubuntu and adjust the configuration files accordingly, i.e. transfer the keys and maybe rename the directory inside /var/lib/bluetooth/<XX:XX:XX:XX:XX:XX>/ accordingly to match the Windows configuration (as described in various tutorials). 9. Thereafter, my mouse worked fine with both, Windows and Ubuntu. ** Description changed: Hello everyone, a few months ago I upgraded from 18.04 to 20.04 and since then, I'm into some bluetooth connection issues. I'm a KDE user currently using Ubuntu 5.4.0-53.59-generic 5.4.65, still the reported issue also appears with plain ubuntu 20.04, even a clean live USB version of ubuntu 20.04 reproduces it such that it is independent of any KDE library. I've noticed the following bug already a few months ago, still I would like to wait and see if it might be resolved with a new kernel update or something else. Since it still persists, I now would like to report it to the devs. I found no similar reported bug but if it already has been reported, I'd like to excuse for reporting a duplicate. So, I'm using a Logitech bluetooth LE mouse and with ubuntu 18.04 (actually on any distro based on 18.04 that I tested), everything works fine and without any problems. Still with 20.04, I'm into the following bug that I would like to report. After starting ubuntu, the bluetooth connection to the mouse works (i.e. pointer is moving) and after about 30-40 seconds it stops moving and freezes for about 10-15 seconds and thereafter works again and stays working. The same issue can be reproduced by executing (for instance on a live ubuntu) sudo /etc/init.d/bluetooth restart which stops the bluetooth connection for a few seconds (as expected), immediately it works again but after additional 30-40 seconds, the connection breaks for another 10-15 seconds and thereafter works flawlessly. I checked all configuration files from the /etc/bluetooth/ directory, everything is the same between 18.04 and 20.04 and even modifying the parameters does not change anything at all. As a conclusion of my testing I strongly guess it has either anything to do with a different kernel version or a with a changed bluetooth library between 18.04 and 20.04. So in summary: Expected behavior: Bluetooth connection shortly breaks after 'sudo /etc/init.d/bluetooth restart' and does not break again after 30-40 seconds (as it is the case with ubuntu 18.04) Actual behavior: Bluetooth connection breaks again after reestablishing the connection - I'm hoping that this issue can easily be fixed and please let me know if you need any further information :-) - --- - ProblemType: Bug - ApportVersion: 2.20.11-0ubuntu27.4 - Architecture: amd64 - AudioDevicesInUse: -
