xcompmgr - sample X compositing manager
xcompmgr [-d display] [-r radius] [-o opacity] [-l left-offset] [-t top-offset] [-acCfFnsS]
xcompmgr is a sample compositing manager for X servers supporting the XFIXES, DAMAGE, and COMPOSITE extensions. It enables basic eye-candy effects.
-d display Specifies the display to manage. -r radius Specifies the blur radius for client-side shadows. -o opacity Specifies the opacity for client-side shadows. -l left-offset Specifies the left offset for client-side shadows. -t top-offset Specifies the top offset for client-side shadows. -I fade-in-step Specifies the opacity change between steps while fading in. -O fade-out-step Specifies the opacity change between steps while fading out. -D fade-delta Specifies the time (in milliseconds) between steps in a fade. -a Automatic server-side compositing. This instructs the server to use the standard composition rules. Useful for debugging. -c Client-side compositing with soft shadows and translucency support. -f When -c is specified, enables a smooth fade effect for transient windows like menus, and for all windows on hide and restore events. -n Simple client-side compositing. This is the default mode. -s Server-side compositing with hard-edged shadows. -C When -c is specified, attempts to avoid painting shadows on panels and docks. -F When -f is specified, also enables the fade effect when windows change their opacity, as with transset(1). -S Enables synchronous operation. Useful for debugging.
