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.
