I'm running Ubuntu 21.04 on a Dell XPS 13 9300.
All of my Bluetooth devices keep disconnecting and reconnecting.
This is a problem as my mouse, keyboard, and headphones all use Bluetooth. I used to be able to use all 3 at once with no problems.
I tried downgrading from kernel 5.11 to 5.10 with no effect.
The problem started sometime this week.
Attached are all of the packages upgraded in the last 3 days, and another list for all from the last 14 days in case none of the newer ones pan out.
Any idea which of these affect Bluetooth?
