I have a ASUS with Ubuntu 20.04 LTS. I have seen that my Bluetooth does not work after a suspend of my computer. The only solution that I have found is restart again the computer. I have tried the solution for this problem Bluetooth does not work after resuming from sleep Ubuntu 18.04, but it does not work. I have already a greater version from bluez 5.53-0ubuntu3.1 that the one that has the problem. My problem is related to this question, but none has response.

I really appreciate any help because I work remotely and I need to have all the time headsets.

Thank you for your time.

I did few tests this afternoon on this subject, and suspects that ubuntu was not properly closing Bluetooth somehow.

Tried to modify : /etc/bluetooth/input.conf, uncommented:

IdleTimeout=5

UserspaceHD=true

And so far, tested with my JBL GO 3, whatever I do the JBL connects again.

Maybe it might need more testing, will try to let you know :)
