    Flaws on Flex 6-14ARR resp. Yoga 530-14ARR using FC28

    Hi,

    I recently purchased a new Lenovo Yoga 530-14ARR, which is a 14" convertible based on AMDs RavenRidge platform. It contains the 2500u, 2x4GB RAM and now 960GB SSD via NVMe on PCI-E 3.0 x2.
    Installing Fedora was quickly done but there are some quirks remaining to be solved for getting all to work. Problems are with the WiFi/Bluetooth, touchpad, touchscreen (and Fingerprint Reader, for a matter of completeness). The inxi -Fxmz is here:
    https://forums.fedoraforum.org/showt...09#post1812309

    Getting the wireless network card (Realtek 8821ce) working was some googling to find out it needed the driver, see
    https://wiki.ubuntuusers.de/WLAN/Karten/Realtek/
    and then to fiddle with the ideapad-laptop kernel module. That needs a patch to include the machines' dmi to a blacklist of Ideapad-like machines with no hardware WiFi-switch. Filed a kernel BZ on this already:
    https://bugzilla.kernel.org/show_bug.cgi?id=200885

    With the touchpad, I had no luck so far. It is only visible from dmidecode, nothing in xinput lshw lspci lsusb /proc/bus/input/devices. It is working under Win10, the bios has no mouse/touchpad/usb related option to toggle and the only information on the actual hardware device from Win10 says it runs on Microsofts default driver for HID-compatible touchpads, combined with the vendor_id 06cb (should be Synaptics). There is no hardware switch for the touchpad and Fn+F6 (disable touchpad) is correctly handled by ideapad-laptop as far as I can tell from on-screen feedback and also does not help to get it working. Updating to the latest BIOS did not help either and from dmesg, the only hint was to enable i8042.nopnp option, which at least gets it to detect a single aux port, but no hardware on it. Been searching the web on this for days now and no real clue anywhere. Kernels that I tried already: 4.16.3, 4.17.17 and 4.17.18. A different user is reporting the same issue under Ubuntu 18.04 at least up to kernel 4.18.4:
    https://bugs.launchpad.net/ubuntu/+s...x/+bug/1787775

    For the touchscreen, I had only a brief look at the issue and it seems to not get detected, albeit xorg.conf has Wacom entries in it, including the libinput override. Need to dig further on that myself, but any hints are welcome as well. It is reported under Win10 as WCOM517E or vendor_id 056a (Wacom) and device_id 517e (unkonwn to the web).

    Has anybody any help for me, especially regarding the touchpad?

    Thanks & Cheers

    Hello aachener.

    Looks like in Advance your "Third Party Software" is not enable on the software Center.
    There you will see the Options to enable the - Linux Vendor Firmware +Vendor Testing repo's.
    I will start from there+After you will Enable those repo's,Open terminal as root User:

    Code:
    dnf clean all
    Then:

    Code:
    dnf --refresh check-update
    OR:

    Code:
    dnf update --nogpgcheck
    BTW - Fedora 28 kernel is now - 4.17.19-200.fc28.x86_64

    To my opinion you need to install - akmod-wl to cover the system needs with your kernel.

    From here:

    https://rpmfind.net/linux/rpm2html/s...query=akmod-wl

    about your issue with the touchpad = > you can configure it in preference => mouse and touchpad.

    reboot the system.
    After you got all done,look in the software Center => Hardware Drivers =>and install there your Drivers.


    Hope that will work for you.

    Hello FFedora,

    thank you for sharing your ideas!
    I enabled third party software and did the clean-refresh-update, but still there is nothing that dnf would like to add to my system. The 'Hardware Drivers'-section of softwarecenter now only offers me Nvidea drivers, which I do not need, but nothing else.
    By 'Linux Vendor Firmware +Vendor Testing repo's', do you mean LVFS/fwupd? -> This is of no help for now, since Lenovo does only support some selected products (not this one) and Realtek, Synaptics or even AMD (for which I do not have any issues) do not support LVFS. Running fwupd itself just reports 'No supported devices'.
    akmod-wl might add some convenience once the system is up and running as desired, but for now, I prefer patching the kernel modules manually.
    As I wrote, the touchpad is not even recognized, albeit there are no options in Preference->Mouse and Touchpad.

    The touchpad is listed as 'MSFT0001' under Win10, for which dmesg gives me following output (if grep MSFT):
    Code:
    [    0.000000] ACPI: SSDT 0x00000000BF7F7000 005367 (v02 LENOVO CB-01    00000001 MSFT 02000002)
    However, the touchscreen is recognized as 'MSFT0002' under Win10...

    How can I tell linux to treat that device as a synaptics touchpad?
