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 ** Affects: bluez (Ubuntu) Importance: Undecided Status: New -- Bluetoothd uses 100% of a CPU thread https://bugs.launchpad.net/bugs/1871695 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
