Plasma Themes and Plugins

How to customize plasma with widgets, themes and icons

The KDE wiki also has a few tutorials which haven’t been ported to yet.

Plasma is very modular. Plasma is shipped with preinstalled modules in your root directory /usr/share/plasma/, however you can also download themes/widgets to the user’s home directory ~/.local/share/plasma/.

  • Plasma Style (formerly called Desktop Theme) controls the panel/widget look.
    • System/Default /usr/share/plasma/desktoptheme/
    • User Installed ~/.local/share/plasma/desktoptheme/ (KDE Store Category)
  • Color Theme (misc colors for Qt5 apps)
    • Usually set in the colors file in a plasma style (desktop theme).
    • When a color theme is applied, it’s values are copied to ~/.config/kdeglobals
  • Icon Theme
  • Task Switcher (Alt+Tab)
  • Plasma Widget (aka Plasmoid) is a small visual plugin in the panel or desktop.
    • System/Default /usr/share/plasma/plasmoids/
    • User Installed ~/.local/share/plasma/plasmoids/ (KDE Store Category)
