    And do not split output - post command with output together.

    https://www.suse.com/releasenotes/x8...SP4/index.html
    What do you think she/he is using?

    But this is the problem:
    juin 22 10:20:26 localhost kernel: rtw_8821ce 0000:01:00.0: rfe 4 isn't supported
    Same error with rfe 2 was not solved by the kernel-team.
    it was solved by Realtek with kernel 5.11 or 5.12.

    Maybe my package is working, but it is build new on OBS, I will give the URL later.

    Thanks for your answers.
    [ I don't split the outputs myself, the forum does it. Even if I edit my post and erase the code that is added between the two parts of the code I want to give you, it reappears again and again. ]
    Could you tell me how I can avoid using the preempt kernel? I'm a very beginner, with a friend of mine who is helping me.
    I will come back to the forum next monday or tuesday.

    Behaviour and kernel were changed in Leap 15.4. Simply do nothing (don't add specific kernel parameter).

    sudo zypper in ./rtw*
    notifications and problems with the signature - I ignored.
    Why ignored? - I did not understand how to proceed (where to get) these signatures.

    You have a lot of FONT and COLOR tags there. Please try, next time, to avoid fonts and colours to be copied with the copy/past.

    Also, I doubt that you get that split when you copy/paste in one move (as is what should be done). Once split and then with all those bewildering FONT and COLOR, I assume that removing some CODE /CODE in between confuses the post editor.

    Because you have downloaded the drivers and not enabled the Repo.
    So you get not the signing key for all rpms in that Repo.

    This key has nothing to do with the uefi cert/uefi-key for secure boot.
    The cert rpm contains the mok-key for the ko-file inside the kmp.rpm.......

    Ok. Added repository:
    Code:
    USR> sudo zypper addrepo home\ Sauerland\ hardware.repo 
    [sudo] password for root: 
    Adding repository 'Hardware (15.4)' ......................................[done]
    Repository 'Hardware (15.4)' successfully added
    
    URI         : https://download.opensuse.org/repositories/home:/Sauerland:/hardware/15.4/
    Enabled     : Yes
    GPG Check   : Yes
    Autorefresh : No
    Priority    : 99 (default priority)
    
    Repository priorities in effect:                (See 'zypper lr -P' for details)
          90 (raised priority)  :  1 repository
          99 (default priority) : 11 repositories
    USR>
    Now this repository has priority = "Default" . 99.
    Leave this priority or set, for example, 98 ?

    If there is no other package with the same name in another Repo, you can use 99, 98, 01 or 120.......
    Priority is only used by installing a new package.......

    Also zypper is not switching any installed package to another Repo by default.

    But now its on Voici to answer, its her/his thread.
