Liquorix Kernel 6.18-13: A Step-by-Step Guide to Improved Performance on Debian, Ubuntu and Arch

Debian 10928 Ubuntu 7099 Arch Linux 964 Published by Philipp Esselbach 0

The Liquorix Kernel 6.18-13 offers improved performance and reduced latency for desktop users and gamers through tweaks such as swapping the default scheduler and adjusting CPU settings. To install this kernel on Debian, Ubuntu, and Arch Linux systems, download the official script using curl and follow its instructions to pull the necessary .deb files from Liquorix's repository. The new kernel replaces the mq-deadline scheduler with Kyber for multiqueue devices and BFQ for single-queue drives, resulting in faster performance during tasks like video encoding and gaming. After installation and a reboot, users can verify that the new kernel is active by checking the system's output from commands like uname -r and /sys/block/sda/queue/scheduler.

Get Started with XanMod Kernels: Installing 6.18.12 and 6.12.73 LTS on Debian-Based Systems

Debian 10928 Ubuntu 7099 Published by Philipp Esselbach 0

The XanMod kernels 6.18.12 and 6.12.73 LTS offer improved performance, including faster compile times and higher throughput for I/O-intensive containers, due to ThinLTO compilation and block layer runqueue changes. To install these kernels on Debian-based systems, users need to import the signing key, add a source list entry, update apt, and install the linux-xanmod-x64v3 meta-package. This process can be simplified into a single flow of fetching the key, writing the repo line, updating apt, installing the kernel package, and rebooting. After installation, users can verify that the new kernel is active by checking /proc/version or uname -r, and ensure their graphics stack has re-initialized correctly using glxinfo | grep OpenGL.
