The XanMod Kernel is a powerful tool that can significantly enhance the performance of your Linux Mint system, particularly in demanding environments. In the following sections, we will delve into the step-by-step process of installing the XanMod Kernel, ensuring that you can leverage its features to the fullest.

The XanMod Kernel is compatible exclusively with x86_64 processor architecture. Moreover, since it doesn’t support secure boot, you’ll need to disable this feature in your system’s settings prior to starting the installation process.

Import XanMod APT Repository on Linux Mint 21 and 20

Step 1: Update Linux Mint Before XanMod Installation

Begin by updating your Linux Mint system. Updating ensures that all existing packages are current, reducing the risk of conflicts during the XanMod Kernel installation.

Execute the following command in your terminal to update the package list:

sudo apt update && sudo apt upgrade

Once the package list is updated, upgrade any outdated packages with this command:

sudo apt upgrade

Step 2: Install Required Packages For XanMod Installation

Now, proceed to install the essential software packages. These packages are necessary for a smooth installation of the XanMod Kernel.

Run this command to install the required packages:

sudo apt install dirmngr lsb-release ca-certificates software-properties-common apt-transport-https dkms curl -y

Step 3: Add XanMod GPG Key and APT Repository

The next step involves adding the XanMod GPG key to your system. This key is crucial for verifying the authenticity of the XanMod packages. Import the key using this command:

curl -fsSL https://dl.xanmod.org/gpg.key | gpg --dearmor | sudo tee /usr/share/keyrings/xanmod.gpg > /dev/null

Following the key import, add the XanMod repository to your system. This repository contains the necessary XanMod Kernel packages. Use this command to add it:

echo 'deb [signed-by=/usr/share/keyrings/xanmod.gpg] http://deb.xanmod.org releases main' | sudo tee /etc/apt/sources.list.d/xanmod-kernel.list

To verify the successful addition of the repository, execute:

grep xanmod /etc/apt/sources.list.d/xanmod-kernel.list

You should see this output, confirming the repository’s addition:

deb [signed-by=/usr/share/keyrings/xanmod.gpg] http://deb.xanmod.org releases main

Step 4: Refresh APT Cache After XanMod Import

Conclude the process by refreshing your APT package index to recognize the newly added XanMod repository. This action ensures your system is ready to install packages from this new source.

Refresh your APT cache with the following command:

sudo apt upgrade

With these steps, you have successfully prepared your Linux Mint system for the XanMod Kernel installation.

Install XanMod Kernel on Linux Mint 21 and 20 via PPA

Download XanMod Kernel Check Script

Begin by downloading the XanMod Kernel Check Script to confirm compatibility with your CPU. This script will identify the appropriate XanMod Kernel package for your system.

Download the script and modify its permissions using these commands:

wget https://dl.xanmod.org/check_x86-64_psabi.sh
chmod +x check_x86-64_psabi.sh

This step is crucial because the XanMod Kernel offers various versions, such as linux-xanmod-x64v1 to linux-xanmod-x64v4, each tailored to different CPU capabilities.

Run the script to find the suitable version:

./check_x86-64_psabi.sh

The output, like CPU supports x86-64-v2, will indicate the supported x86-64 version. Your result might show x86-64-v1, v3, or v4, depending on your CPU.

Verify XanMod Kernel Installation on Linux Mint 21 and 20

Checking the Installed Kernel Version

To verify the XanMod Kernel installation on your Linux Mint system, it is crucial to check the currently running kernel version. This is easily done using the terminal.

Execute the following command to display your system’s kernel information:

cat /proc/version

This command outputs the contents of the /proc/version file, providing detailed information about the active kernel. For a more focused output, specifically the kernel release version, use:

uname -r

This command succinctly displays the kernel release information, helping you confirm the active kernel version.

Enhancing System Information Display with Neofetch

For a comprehensive overview of your system, including the kernel version, consider installing Neofetch. Neofetch is a command-line utility that displays extensive system information in a visually appealing format.

Install Neofetch using this command:

sudo apt install neofetch -y

The -y flag automatically confirms the installation, streamlining the process.

Once installed, run Neofetch to view a detailed summary of your system’s specifications:

Executing Neofetch will present you with a thorough summary that includes the kernel version, hardware details, and operating system information, providing a complete picture of your system’s status.

Install Intel or AMD Official Microcodes on Linux Mint 21 and 20

Installing Intel Microcode

For Linux Mint users with Intel processors, it’s essential to keep the microcode up-to-date. Microcode updates are vital for CPU stability and security, as they can rectify processor bugs and improve performance. Linux Mint enables easy microcode updates through its package management system.

Run the following command to install the latest Intel microcode:

sudo apt install intel-microcode iucode-tool

This command installs intel-microcode, containing the latest microcode binaries from Intel, and iucode-tool, a utility for handling microcode updates. Keeping your Intel CPU’s microcode updated ensures optimal performance and security.

Installing AMD Microcode

For Linux Mint systems equipped with AMD processors, updating the microcode is just as important for ensuring CPU performance and security. Linux Mint provides a streamlined approach for these critical updates.

To install the AMD microcode, execute this command:

sudo apt install amd64-microcode

This command installs amd64-microcode, the package containing the latest microcode updates for AMD CPUs.

Managing XanMod Kernel on Linux Mint 21 and 20

Update XanMod Kernel on Linux Mint

Keeping the XanMod Kernel updated is crucial for optimal performance and security. If you’ve installed XanMod via APT, as detailed in earlier guides, the update process is simple and straightforward.

First, check for available updates by running:

sudo apt update

If updates are available, proceed to upgrade your system with:

sudo apt upgrade

These commands ensure that your XanMod Kernel remains up-to-date with the latest improvements and security patches.

Remove XanMod Kernel From Linux Mint

Before uninstalling XanMod, it’s important to delete the previously added repository to prevent future updates for XanMod.

Remove the repository with this command:

sudo rm /etc/apt/sources.list.d/xanmod-kernel.list

To completely remove all components of the XanMod Kernel, execute:

sudo apt autoremove linux-image-*.*.*-xanmod* linux-headers-*.*.*-xanmod* --purge

This command will search and remove any XanMod packages installed on your system. This command is quite aggressive and will also remove any unused packages that are leftovers from other installations; in most cases, this is fine and ideally, none should exist anyway.
