Hi,
I have a bluetooth keyboard that I use for my laptop, which runs Kubuntu 19.04. I noticed though, that a short while after connecting the keyboard, the CPU fan goes on and one of the threads is at 100%. If I open a terminal and type "top", it shows that a process called bluetoothd is taking 12% of the CPU power which is a full thread (100/8=12.5). I'm not sure what it's doing, but it doesn't require that much CPU power to work. If I end the process and restart it, the keyboard works fine and the CPU is calm until it happens again (about 20 minutes later). I reinstalled bluez and even tried recompiling from source, but the problem persists.
My specs:
Version of bluetoothd: 5.50
Linux Kernel: 5.3.0-46-generic
KDE Plasma Version 5.16.5
Thank you,
Isaac Cohen |
