The Liquorix Kernel is a specialized Linux kernel optimized for performance, particularly in desktop environments and for multimedia applications. By switching to Liquorix, users can experience enhanced responsiveness, lower latency, and improved performance in CPU-intensive tasks.
Why Switch to Liquorix Kernel?
- Enhanced Performance: Significant improvements in responsiveness and overall system performance.
- Lower Latency: Better handling of CPU-intensive tasks, ideal for gaming and multimedia applications.
- Optimized for Desktop Use: Fine-tuned settings for desktop environments.
Important considerations to understand before installing the alternative Linux Kernel:
- Compatibility: Designed for systems with x86_64 processor architecture. Note that it is incompatible with ARMHF or ARM64 devices like Raspberry PI.
- Security Considerations: Secure boot is not supported, so ensure to disable it in your system’s BIOS settings before installation.
With these details in mind, let’s explore how to install the Liquorix Kernel on Ubuntu 24.04, 22.04, or 20.04 LTS using the command-line terminal.
Update Ubuntu Before Liquorix Kernel Installation
Before we begin the installation process, ensuring that your system is up to date with the latest packages is essential. To do this, execute the following commands in your terminal:
sudo apt update
sudo apt upgrade
The first command updates the package list, while the second upgrades outdated packages to their latest versions.
Import the Liquorix Kernel PPA
The Liquorix Kernel team offers support through a Liquorix Launchpad PPA (Personal Package Archive), making installing and maintaining the kernel easy. Run the following command to import the Liquorix Kernel PPA:
sudo add-apt-repository ppa:damentz/liquorix -y
This command adds the Liquorix repository to your system’s sources.list file.
Next, run a quick update to refresh the APT repository cache, which must be done before the installation:
sudo apt update
Finalize Liquorix Kernel Installation via APT Command
Now that the Liquorix Kernel PPA is available on your system, you can start the installation process. Use the following command to install the Liquorix kernel:
sudo apt install linux-image-liquorix-amd64
After the installation is complete, reboot your system to activate the newly installed Liquorix kernel:
reboot
Verify the Liquorix Kernel Installation
Once your system has restarted, you can verify that the Liquorix kernel is active by checking the output of the /proc/version
file. Use the following command to display its contents:
cat /proc/version
Example output:
Linux version x.x.x-x-liquorix-amd64
The output should display the Liquorix kernel version, which may vary depending on the current version available in the PPA.
Additional Liquorix Kernel Commands
Update Liqourix Kernel
To ensure that the Liquorix kernel remains up-to-date, you should periodically run the apt update and upgrade commands, as you used the APT package manager to install the kernel.
Run the command “apt update” to check for updates on packages managed by APT.
sudo apt update
If updates are available, use the following command to upgrade all packages, including the Liquorix kernel.
sudo apt upgrade
Remove Liqourix Kernel
Remove Liquorix Kernel PPA
If you have decided not to continue using the Liquorix kernel and wish to remove the PPA, use the following command.
sudo add-apt-repository --remove ppa:damentz/liquorix -y
Check Liquoirx Installed Packages
Note that you must specify the exact name of the Linux image and header package to remove them. You can find the names by running the following command.
dpkg --list | grep `uname -r`
Remove Liquorix Kernel
To remove the kernel packages, use the provided command, which should cover all versions of Liquorix. However, modify the command to match the kernel version in your output if necessary.
sudo apt-get autoremove linux-image-*.*.-*.*-liquorix-amd64 linux-headers-*.*.*-*.*-liquorix-amd64 --purge
While removing the Liquorix Kernel, you may encounter a prompt asking for confirmation to proceed with the removal.
During the removal process for the Liquorix Kernel, a warning message may appear about not having a fallback Linux Kernel to rely on during a reboot. Selecting “No” to proceed with the removal process is essential.
Re-Install Generic Ubuntu Kernel
Once you have removed the Liquorix kernel, run the following command to ensure the generic Linux Kernel is installed. You can change this later for users who want something else.
sudo apt install linux-image-generic
Note: Alternatively, you could install the HWE Kernel to suit your Ubuntu system better for Ubuntu LTS release variants.
Reboot and Verify Restored Ubuntu Default Kernel
Now restart your PC to finalize the removal of Liquorix:
reboot
To confirm that the Liquorix kernel has been successfully removed, you can check the installed kernel version using a command like “cat /proc/version” and compare the output to the version of the Liquorix kernel you had previously installed.
cat /proc/version
Example output if the default kernel is restored:
Linux version x.x.x
Conclusion
We’ve walked through the steps to install the Liquorix Kernel on Ubuntu 24.04, 22.04, and 20.04 LTS, using the Liquorix LaunchPAD PPA for easy setup and updates. This guide aims to enhance your system’s performance, particularly for gaming and intensive applications. Remember, Liquorix is best suited for x86_64 architectures and requires secure boot to be disabled. Keep an eye on kernel updates through the PPA to maintain optimal performance.
