KDE App of the Week: Wallpaper Effects

If you want to enhance your KDE Plasma desktop with stylish effects, you should take a closer look at the Wallpaper Effects widget. Inspired by projects like Active Blur, this widget brings a variety of effects to all wallpaper plugins.

Features and Functions

With Wallpaper Effects, you can make numerous visual adjustments to your desktop background. The customizable blur effect allows for individual softening, including rounded corners, shadows, and color adjustments. Additionally, you can modify color and contrast settings such as brightness, saturation, and hue.

Another highlight is dynamic effect control: effects can be activated, for example, only for maximized windows or active applications. Integration with existing KDE desktop effects is also possible. For those who prefer shader effects, there are the Pixelate filter with adjustable pixel size or the animated Grain filter with variable intensity.

Installation

To install the widget on TUXEDO OS, right-click on an empty space on the desktop and select Enter Edit Mode from the context menu. In the editor mode, click Add or Manage Widgets… at the top left.

In the sidebar with the currently installed widgets, select Get New Modules… and then click Download New Widgets. This will open the KDE extension store, where you can search for „Wallpaper Effects“ and download the widget by clicking Install….

Configuration

After installation, simply place the widget on your desktop. In the widget settings under Set up Wallpaper Effects…, you can adjust the desired effects. If you only want the widget to appear in edit mode, activate the Hide Widget option.

All adjustments are not permanent: If you want to undo changes, uncheck the Enabled option in the widget settings or remove the widget from the desktop.

With Wallpaper Effects, KDE Plasma gains a powerful tool for personalizing your desktop. Thanks to the variety of options, effects can be precisely adjusted and toggled on or off – ideal for users who want to enhance their desktop without having to dive deep into the system.
