From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

kAppIcon: Change individual Linux app launcher icons without root (lemmy.world)

I made a small tool for KDE Plasma (and other freedesktop desktops) that lets you easily customize single app icons:

Use your own images or library
Copy icon from another app
Pick one icon from any installed theme (without switching global theme)
Built-in pixel editor to create your own
Batch apply, undo, overrides, missing icons overview
Import image to turn it into an icon

Completely user-level, safe, and reversible. No manual .desktop editing.

AUR: kappicon or kappicon-git

It should work with most window managers, but with some limitations. kAppIcon edits user-level .desktop files and installs icons into your personal ~/.local/share/icons/hicolor theme. This is the standard freedesktop way, so it works on any desktop/WM that respects the spec (most do).

However: The GUI is built with PyQt6, so you need a working Qt6 environment (works fine on Wayland too). Some features like automatic icon cache refresh or menu updates depend on the desktop environment (Plasma does it best, but it also runs gtk-update-icon-cache for GTK-based setups).

On pure minimal WMs (i3, Hyprland, etc.) it will still apply the icons, but you may need to restart your menu/panel or run update-desktop-database manually sometimes. If you test it, let me know how it goes.
