A harmless ACPI warning about missing Bluetooth reset support may appear in your Ubuntu boot logs. This post explains what it means, why it happens, and how to fix or hide it — plus when it might actually signal a real Bluetooth issue.
Learn how kernel.printk controls what your Linux kernel says (and what it keeps to itself). We’ll explore log levels, security implications, and how kernel.printk = 3 3 3 3 helps your system stay silent, secure, and sensible.
Continuing my dual-GPU adventure, this post dives into OpenGL performance on Ubuntu 25.10 using two RTX 2080 Ti cards—no NVLink, no PRIME, no Optimus. We’ll test rendering behavior, driver differences, and benchmark real-world results with glxgears and glmark2.
Frequent i915 atomic update errors in your Linux kernel logs? On Dell XPS 15 laptops with hybrid Intel–NVIDIA graphics, these messages usually point to race conditions in the Intel i915 driver. Learn what causes them, how to fix or mitigate them, and when it’s safe to simply ignore the noise.
Learn how kernel.dmesg_restrict protects your Linux system by limiting who can read the kernel’s ring buffer. A small setting with a big security impact — keeping sensitive kernel messages away from prying eyes.
A deep dive into the wild side of Linux performance tuning — disabling mitigations, isolating cores, and bending the kernel to your will. This story walks you through the dangerous beauty of chasing every microsecond of speed.
Snap packages offer a more flexible and distribution-agnostic method of software installation that includes all the necessary dependencies within a single package, thus making it easier to distribute and install software across various Linux distributions.
While exploring my kernel logs, I found a harmless but annoying error about ALSA’s restore rules. Turns out, it’s a missing label in a udev rule! Here’s what caused it, why your sound still works fine, and how to patch it manually without waiting for Ubuntu’s update.
