    Lenovo FLEX 6 14ARR mousepad, keyboard functions and backlight F30 kernel 5.1.20-300

    Hello,

    I have this new laptop 2-1 I know it has issues with drivers. I have been testing different distros, so the one that worked best was fedora; now I am trying to finish the setup. I installed it and updated everything.
    The WIFI its not working but there are post about it, its the Realtek rtl8821ce, I al ready have the driver but I do not want to mess it up, so I will do it when I am certain that I am doing it the right way, I just have doubts about how can I be sure that the DKMS its installed in my fedora, if I do not have it, then how can I install it?.

    Now, the mousepad or trackpad its not working and I would also like to get the function keys working (if possible) I think its a backlight issue? . Any help or guidance with this 2 devices would be appreciated.

    I will keep searching on the web in the mean time.

    PS

    Fedora 30 Kernel 5.1.20-300

    Muchas gracias

    Re: Lenovo FLEX 6 14ARR mousepad, keyboard functions and backlight F30 kernel 5.1.20-

    So tried to install the rtl8821ce driver and sent me an error
    Code:
    [arturorivas@flex-6-14arr ~]$ cd rtl8821ce/
    [arturorivas@flex-6-14arr rtl8821ce]$ sudo ./dkms-install.sh
    [sudo] password for arturorivas:

    DKMS: add completed.

    and then I tried the solution Hogweed gave in the thread "Will rtl8821ce wireless driver be mainlined?" with this result
    Code:
    [arturorivas@flex-6-14arr rtl8821ce]$ chmod +x dkms-install.sh

    Any help would be appreciated.

    As the error message says, you need to install the kernel headers:

    dnf install kernel-headers kernel-devel

    Re: Lenovo FLEX 6 14ARR mousepad, keyboard functions and backlight F30 kernel 5.1.20-

    The WIFI rtl8821ce I got it working, but in this version of linux I did this.
    Install dkms

    sudo dnf install dkms

    Then you need to get this that will fix an error with kernel headers

    sudo yum install kernel-devel

    Then you reboot (I am not sure if needed)

    Then you have to get the drivers for the WIFI and Touchpad

    git clone https://github.com/tomaspinho/rtl8821ce.git
    git clone https://github.com/Syniurge/i2c-amd-mp2.git

    then installing them; I did it one by one because I do not know how to do them at same time)


    ls

    Desktop Documents Downloads i2c-amd-mp2 Music Pictures Public rtl8821ce Templates Videos[./code]

    cd rtl8821ce

    Then

    sudo ./dkms-install

    then

    cd ..

    cd i2c-amd-mp2/

    and do the same for installing

    sudo ./dkms-install

    so far i am missing the functions key or backlight, but i am very happy of how its behaving.
