All About Linux.

Screen annotation tools draw directly over everything on your desktop, so you can circle a button in a demo video, sketch an idea during a call, or mark up a screenshot without opening an image editor. On Linux, several free tools do this well, and each takes a different approach: a GNOME extension, a KDE

The error gzip: stdin: not in gzip format appears when tar hands the file to gzip for decompression and gzip finds data that is not a gzip stream. The usual cause is simple: the file was never compressed, it is a plain tar archive that someone renamed to .tar.gz. Here is the command that triggers

When a USB drive mounts itself the moment you plug it in, or a symlink appears in /dev for your new disk, that is udev at work. The udevadm command is the control tool for that system: it shows what the kernel knows about each device, replays device events, and applies the rules stored in

That cascade of green characters falling down a terminal screen is one of the most recognizable effects in Linux culture. A small program called cmatrix reproduces it in any terminal emulator, and it takes one package-manager command to install. The same commands work across Debian, Fedora, and Arch derivatives. Everything below was re-run on an

Most Linux desktops ship with a default terminal emulator chosen by the desktop environment, such as GNOME Terminal or XFCE Terminal. Kitty is a GPU-accelerated alternative that renders text on your graphics card instead of the CPU. It supports true color, ligatures, tiling windows and tabs inside one process, and a graphics protocol that can

Windows shows your Linux partition in Disk Management but refuses to open it. Linux distros read NTFS drives out of the box, yet Microsoft ships no driver for the ext4, ext3, or ext2 file systems, so a dual-boot machine leaves every Linux file unreachable until you reboot. Each option below solves a different part of

A Raspberry Pi GUI turns the little board from a command-line-only machine into something you point and click through, just like a regular desktop. Raspberry Pi OS ships a Lite edition with no desktop at all, so plenty of owners end up adding one later. This guide covers installing it, booting straight into it, reaching

Wayland’s fractional scaling keeps the desktop sharp on a HiDPI screen, but Steam and the games it launches often get a completely different picture. A monitor set to 150% or 200% scaling gets reported to games as a smaller, lower-resolution display, so a title like Portal 2 or a Proton game such as Rocket League
