Chapter 3.2.16 Window Effects¶
Window effects is the default program in Lubuntu to manage effects of the Compton X compositor.
The Shadow tab manages how compton draws shadows. To toggle enable client side shadows press the Enable client side shadows checkbox. The checkbox for Avoid drawing shadows on dock/panel windows will stop drawing shadows on the panel. The Color of shadow lets you change the color of shadows from windows. The field for The blur radius for shadows changes how big to blur the shadows. The left offset for shadows is how far to move the shadows to the left with a larger number makes the shadow appear farther to the right. The top offset for shadows the larger the number farther down the shadow appears below the window. The translucency for shadows is how opaque or clear to make the shadows 1 is opaque shadows and 0 is clear. The Crop shadows of maximized windows from extended displays checkbox does not have shadows across multimonitor layouts on other monitors from windows on another.
The Opacity tab is for transparency settings. Setting Opacity to 1.00 makes it opaque while 0 makes it entirely clear. Menus, inactive windows, active windows, and titlebars and borders all can have their opacity changed independently. To not change how bright or dim windows are with window opacity check the Do not let dimness adjust based on window opacity. The Blur background of transparent windows blurs the background of transparent windows. To not change how far a window blurs on window transparency check the Do not let blur radius adjust based on window opacity.
The Fade tab manages fading windows opening or closing or opacity changes. There is a checkbox for Fade windows during opacity changes so if the opacity changes it will smoothly fade. To have a slower time between fade in milliseconds increase The time between steps in a fade in milliseconds. To change how much to change opacity while a window is fading in change Opacity change between steps while fading in field. To change steps when fading out change Opacity change between steps while fading out field. With this settings windows will fade in and out when opened and closed unless you don’t them to which you can check the Avoid fade in out when windows opening/closing.
The Other tab has settings for changing the backend of how compton renders things. The Rendering backend changes what compton uses to render the window effects. To switch to hardware accelerated rendering of the compton backend press the GLX(OpenGL) button. To change back to the default rendering press the X Render button.
To have your settings applied you will need to press the Apply button. If you want to cancel your changes press the Cancel button. If you want to close Window Effects press the
