Thread: NVIDIA Optimus fan is constantly ON. (LEAP 42.3)

    Default NVIDIA Optimus fan is constantly ON. (LEAP 42.3)

    Hello,
    I recently upgraded from Leap 42.2 to 42.3 and I am using the latest KDE (KDE Plasma: 5.11.4, KDE Frameworks: 5.40.0, Qt Version: 5.10.0). After the upgrade, my NVIDIA graphics card fan is constantly ON, even when I am just browsing. I did not have this problem in Leap 42.2 so I uninstalled NVIDIA driver and currently using Nouveau with Bumblebee. I followed this link https://en.opensuse.org/SDB:NVIDIA_Bumblebee and changed the following line
    in /etc/bumblebee/bumblebee.conf:
    Code:
    [bumblebeed]
    Driver=nouveau
    and restarted Bumblebeed

    Code:
    sudo systemctl restart bumblebeed
    The fan is still on. Here are some information
    Code:
