Install the Kernel Clear Kernel on Fedora 28 and derivatives

clear linux

El Linux kernel that different distributions usually launch, it is usually as generic as possible, since the users are many and each one with a different equipment and configuration. Although there are some modified versions, which are designed to certain aspects or improvements, such as the CK Kernel.

For Fedora users, they have been working on a kernel that is focused on Intel processors, which is borrowed from Clear Linux, which is a minimal distribution designed primarily for cloud performance and use cases.

About the Clear Linux Kernel

Due to performance improvements and satisfactory result, a Fedora user decided to take over and compile the Kernel Clear for distribution.

The compilation was actually part of a discussion on the Fedora development roster, as the issues of Clear Linux optimizations have been raised which caught the attention of the developers.

So in this way it is understood that these optimizations would be relevant for Fedora users who run the system on computers with Intel processors and can obtain better system performance using this kernel.

The Linux kernel "Clear" is fully optimized for machines using Intel processors and other devices.

This open source project from the Intel Technology Center which with Intel engineers invest heavily in performance optimizations via AutoFDO, LTO-optimized binaries, aggressive compiler options by default, and much more.


The purpose of this kernel is to mimic performance similar to the Intel Clear Linux operating system on Intel-based machines. using the Fedora operating system.

The kernel only supports the accelerated performance of Intel CPUs, therefore, in computers with AMD processors, the use is not recommended or guaranteed.

It is important to mention before going to the installation process, that at the moment only the Kernel is compatible with Intel graphics, so Nvidia and AMD graphics are not supported.

So the installation of this Kernel is only recommended for Notebooks, Laptops and even desktop computers that only use an Intel processor and their graphics.

In addition to this, neither the developers, the users who have made this port and above all we are responsible for the misuse or the Kernel already described, the requirements that are needed for the optimal functioning of this Kernel.

If you are not sure what to do, it is strongly recommended that you better run some tests on a virtual machine.

Installing Clear Kernel on Fedora 28 and derivatives

fedora 28

In order to install this Linux Kernel on the system, we must follow the steps that we share below.

Firstly, we must update the system, we do this by opening a terminal and typing the following command in it:

sudo dnf update

Done this we are going to proceed to enable a repository in the system, we do this with the following command:

sudo wget -O /etc/yum.repos.d/pac23-High_Performance_Clear_LInux_kernel_for_Fedora-fedora-28.repo

Already added the repository, just type the following command:

sudo dnf update

Once this is done, we will be notified that there is a Kernel update and it will ask us if we want to proceed, just type "s" to start the download and installation of Kernel Clear on our system.

At the end of the installation it is necessary that we restart the system to start with the new Kernel in it.

And ready with it, you will be using this Kernel optimized for Intel processors.

In the same way, you can learn a little more about Clear Linux in its official project blog the link is this.

On the other hand, if you want to know a little more about the project that Fedora users are carrying out with this Kernel, you can visit the following link where you can have contact with the person in charge. The link is this.

    when I add the repository to it, it gives me an error and says the url is missing. Do you know why this happens to me?

    The command is not spelled correctly. Anyway, the quickest thing you can do is manually enter the URL of the last command, which is the content of the repository file, and you create a blank file, pasting said content, call it whatever you want and put the repo extension on it. , and then, as administrator, you move it to the /etc/yum.repos.d/ folder
    Then you update and it works perfectly.

    As the article says, EVERYTHING is optimized for intel. I say this because if you have, for example, a bluetooth mouse of another brand, you may have problems (in my case, with this kernel, the buttons work for me but not the scrolling ...). With the latest standard kernel (the Koji builds) it works perfectly for me.
    I'll keep an eye on this version, just in case any fixes / updates come to it.

    Not that it is wrong: The command is unique, but it has been separated into 3 lines: first part, a space, and second part.
    If you want to make a copy / paste you only have to copy the first row in the terminal, then leave a space and copy the last instruction.
    Then you press ENTER and that's it.

    The option given by Miguel Angel is also valid.
