Install Liquorix Kernel on Debian 11

In this tutorial, we will show you how to install Liquorix Kernel on Debian 11. Are you looking for a way to improve the performance of your Debian 11 system? Consider installing the Liquorix kernel, a popular alternative to the default kernel that comes with Debian. The Liquorix kernel is optimized for desktop use and offers several performance benefits over the default kernel, including lower latency and improved responsiveness.

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the Liquorix Kernel on a Debian 11 (Bullseye).


  • A server running one of the following operating systems: Debian 11.
  • It’s recommended that you use a fresh OS install to prevent any potential issues.
  • SSH access to the server (or just open Terminal if you’re on a desktop).
  • An active internet connection. You’ll need an internet connection to download the necessary packages and dependencies for Liquorix Kernel.
  • A non-root sudo user or access to the root user. We recommend acting as a non-root sudo user, however, as you can harm your system if you’re not careful when acting as the root.

Benefits of Using Liquorix Kernel

When it comes to optimizing the performance of your Debian 11 system, options are available for tweaking the kernel. One such kernel that has been gaining popularity among Debian users is Liquorix Kernel. It’s an optimized kernel that provides significant improvements in system responsiveness and overall throughput. In this section, we’ll explore a few key benefits of using the Liquorix Kernel on Debian 11.

1. Improved System Responsiveness

The Liquorix Kernel is designed to enhance system responsiveness, making your desktop feel snappier and faster. The CPU scheduler in this kernel has been optimized for desktop use, meaning that it prioritizes interactive tasks, such as opening applications, switching between windows, and browsing the web. As a result, your system feels more responsive to your actions.

2. Better Gaming Performance

If you’re a gamer, the Liquorix Kernel can help improve your gaming performance on Debian 11. The kernel has been optimized for low-latency operation, which means that it strives to reduce input lag and improve overall frame rates. The Liquorix Kernel also supports several gaming-related features, such as the BBR congestion control algorithm, which ensures that your gaming traffic gets the lowest possible latency.

3. Newer Hardware Support

The Liquorix Kernel is built on top of the latest stable kernel release, which means that it provides support for the latest hardware and drivers. If you’re using newer hardware, such as the latest graphics card or high-end sound card, you’ll benefit from using the Liquorix Kernel instead of the default Debian 11 kernel.

4. Easy Installation and Maintenance

Installing the Liquorix Kernel on Debian 11 is straightforward, thanks to the availability of pre-built packages. The developers also maintain a repository that provides regular updates to the kernel, making it easy to keep your system up-to-date. Furthermore, the Liquorix Kernel packages integrate well with the existing Debian system, so you can continue to use Debian tools to manage your system.

Install Liquorix Kernel on Debian 11 Bullseye

Step 1. Before we install any software, it’s important to make sure your system is up to date by running the following apt commands in the terminal:

sudo apt update
sudo apt upgrade
sudo apt install curl ca-certificates apt-transport-https software-properties-common lsb-release

Step 2. Installing Liquorix Kernel on Debian 11.

  • Method 1.

By default, Liquorix Kernel is not available on the Debian 11 base repository. So, now run the following command below to download the installer script to your Debian system:

curl -s '' | sudo bash

The command will download the Liquorix Kernel installation script and execute it with root privileges. The installation process will take a few minutes, depending on your system’s hardware specifications and internet speed. Once the installation is complete, reboot your system to load the new Liquorix Kernel:

  • Method 2.

Now we add the Liquorix repository to your list of repositories:

sudo add-apt-repository ppa:damentz/liquorix

After the Liquorix repository is added, you can install the kernel using the following command below:

sudo apt install linux-image-liquorix-amd64 linux-headers-liquorix-amd64

Once the kernel installation is complete, reboot your system:


Step 3. Configuring Liquorix Kernel on Debian 11.

After installing Liquorix Kernel on Debian 11, you can configure it by editing the grub configuration file. Open the terminal and run the following command to open the grub configuration file:

nano /etc/default/grub

In the grub configuration file, find the line that starts with “GRUB_DEFAULT=” and change its value to “0“. This will set the Liquorix Kernel as the default kernel to boot. Save the changes and exit the editor.

Next, update the grub configuration by running the following command:

sudo update-grub

The update-grub command will detect the installed kernels on your system and update the grub configuration accordingly.

Step 4. Checking Liquorix Kernel Version.

To check the version of Liquorix Kernel installed on your Debian 11 system, open the terminal and run the following command:

uname -r

In addition, you can check Liquorix Kernel installed using Neofetch:
