    Lenovo ideapad FLEX 6-14ARR no trackpad no touch/pen no wifi

    I recently picked up the Lenovo Flex 14 (AMD) here in Canada. It's a 2 in 1 convertable.

    Installing ubuntu was simple, but wifi refused to work. It seems to be hardblocked and blacklisting "ideapad_laptop" temporarily solves the issue. I say temporarily because it disables many features of the device, like its auto rotate and trackpad disable for tent mode.

    I've found posts about other lenovo laptops from 2014, where users were able to compile their own "ideapad_laptop" module and solve their wifi issue without having to disable other features.

    I'm not sure how to go down that road, and I also would love some help with my touchpad, touchscreen and pen issues.

    I guess I can't help as I don't use the 4.18.6 kernel. Actually file a bug report against package linux, see https://ubuntuforums.org/showthread.php?t=1011078 for some help. You might also have to file a bug at kernel.org as this is not fixed even in the newest Linux kernel source code

    4.15 will be the same, but I do have source code for it.
    Code:
    cd /lib/modules/4.15.0-33-generic/kernel/drivers/platform/x86
    sudo wget https://www.dropbox.com/s/nxu7b0lyj02bv4n/ideapad-laptop.ko
    Delete the blacklist on ideapad-laptop, reboot, check UEFI/BIOS settings, make sure Secure Boot is disabled. I think it will work

    Okay, successfully
    transferred, removed blacklist, rebooted, SecureBoot is disabled, but it isn't working.
