.SH DESCRIPTION
.B xcompmgr
@ -12,6 +12,9 @@ is a sample compositing manager for X servers supporting the XFIXES, DAMAGE,
and COMPOSITE extensions. It enables basic eye-candy effects.
.SH OPTIONS
.TP
.BI \-d\ display
Specifies the display to manage.
.TP
.BI \-a
Automatic server-side compositing. This instructs the server to use the
standard composition rules. Useful for debugging.
@ -21,15 +24,25 @@ Client-side compositing with soft shadows and translucency support.
.TP
.BI \-f
When \-c is specified, enables a smooth fade effect for transient windows like
menus.
menus, and for all windows on hide and restore events.
.TP
.BI \-n
Simple client-side compositing.
.TP
.BI \-s
Server-side compositing with hard-edged shadows.
.TP
.BI \-C
When \-c is specified, attempts to avoid painting shadows on panels and docks.
.TP
.BI \-F
When \-f is specified, also enables the fade effect when windows change their
opacity, as with transset(1).
.TP
.BI \-S
Enables synchronous operation. Useful for debugging.
.SH BUGS
Several.
Probably. Please report any you find to http://bugs.freedesktop.org/.
