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 18.04
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 :-)
