    Bluetooth icon missing on the top bar

    Hi,
    I use Mantic Minautor on a 14s-fq hp laptop.
    My Q.live 1242 wireless earphones are not detected.
    No bluetooth icon in the right topbar.

    A few details:

    In terminal check
    Code:
    mokutil --sb
    Secure Boot will need to be disabled for it to work, then
    Code:
    sudo apt install git dkms
git clone https://github.com/jeremyb31/bluetooth-6.5.git
sudo dkms add ./bluetooth-6.5
sudo dkms install btusb/4.1
    Reboot

    Re: Bluetooth icon missing on the top bar

    Hi,
    Thank you very much for your answer.

    I made the changes.

    There isn't any icon in top bar.
    My earphone devices cannot be connected.

    Before the changes I noticed that launching the device search froze Freetuxtv.

    Ciao
