Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem?

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.14 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

Hello Joseph!

I remember the Bluetooth used to work correctly when I first installed
Ubuntu on my laptop, but unfortunately I cannot tell after which update
it ceased to work because I have not been using the Bluetooth for a long
time.

A compromise solution would be to use an external USB Bluetooth dongle,
which has proved to work fine.
But still I would prefer to use my laptop's internal Bluetooth adapter
if possible.

I will try to install the upstream kernel and let you know.

Thank you very much for your help!

Paolo
