I have been running a Steam Cache on my home server for years, and the single upgrade that moved the needle the most was replacing the mechanical drives with a dedicated SSD cache. When I first set up Lansweeper’s open-source Steam caching setup, downloads crawled and family members queued up for the same 80GB games … Read more
If you run Pi-hole and still see ads popping up on your smart TV, chances are a device on your network is bypassing your ad-blocker entirely. Many IoT devices, streaming sticks, and even smartphones ship with hardcoded DNS servers like 8.8.8.8 or 1.1.1.1 baked into their firmware. When that happens, your Pi-hole DNS sinkhole never … Read more
If you have switched to Wayland and suddenly started seeing horizontal lines, flickering windows, or stuttering fullscreen video, your NVIDIA driver is the likely culprit. I have spent the last several months troubleshooting this exact issue across GNOME, KDE Plasma, and Sway, and I am going to walk you through what actually works in . … Read more
You install the NVIDIA driver on Ubuntu, reboot, and the screen stays black. That is the single most common NVIDIA-on-Ubuntu problem, and you can recover from it. The fix usually boils down to purging the driver, regenerating or deleting a stale /etc/X11/xorg.conf, picking the right version with ubuntu-drivers autoinstall, and only adding nomodeset when nothing … Read more
Getting a USB Wi-Fi adapter working on Linux with an out-of-tree DKMS driver is one of those tasks that looks intimidating until you have walked through it once. I have compiled and reinstalled drivers for more Realtek chipsets than I can count, and I still keep notes because the incantations are easy to forget. This … Read more
Learning how to fix a Linux laptop that won’t wake from suspend is one of those troubleshooting skills that every laptop user eventually needs. Whether you are running Ubuntu, Fedora, Linux Mint, or Arch, at some point your laptop closes its lid, you open it later, and the screen stays pitch black. No response, no … Read more
When I plugged my first 4K monitor into a Linux laptop, everything looked razor-sharp at 100% scaling and hilariously huge at 200%. I spent the next month bouncing between integer scales, hunting down a sweet spot. That hunt led me deep into Linux fractional scaling, the murky difference between Wayland and X11, and the real … Read more
When your wireless card drops, your GPU misbehaves, or a PCIe device goes silent, the first question I always ask is: which kernel module is supposed to be running this thing? Linux exposes that answer through two commands: lspci and lsmod. I use them together almost every time I troubleshoot hardware on a server or … Read more
You plug in your HDMI cable, the display mirrors perfectly, and then you realize your audio is still coming from the laptop speakers. If you are dealing with HDMI audio not working on Linux, you are not alone. This is one of the most common issues Linux users face when connecting to a TV or … Read more
Getting an AMD GPU running on Linux used to be painful. I remember fighting with proprietary Catalyst drivers back in 2012 and being grateful when the open-source AMDGPU stack finally landed in the kernel. Today, the situation is dramatically better — most Linux distros boot, detect, and accelerate an AMD Radeon card out of the … Read more
