[compiz] compiz run on DISPLAY :2 error: No composite extension

[Zhu, Jack]

I can enable compiz on default DISPLAY :0  on gnome on FC6,  all
features are OK, but when I set up a DISPLAY :2 with Xnest,  try to run
compiz in DISPLAY :2, fail, 

Error info: 

 

compiz: No composite extension 

 

I check compiz source code: 

if (!XQueryExtension (dpy,

                              COMPOSITE_NAME,

                              &d->compositeOpcode,

                              &d->compositeEvent,

                              &d->compositeError))

    {

         fprintf (stderr, "%s: No composite extension\n", programName);

         return FALSE;

}

 

NAME

       XQueryExtension, XListExtensions, XFreeExtensionList - list
available extensions

ARGUMENTS

       display   Specifies the connection to the X server.

       name      Specifies the extension name.

DESCRIPTION

       The  XQueryExtension  function  determines  if  the  named
extension is present.  If the extension is not

       present, XQueryExtension returns False;  otherwise,  it  returns
True.   If  the  extension  is  present,

       XQueryExtension  returns  the major opcode for the extension to
major_opcode_return; otherwise, it returns

       zero.  

 

 

who can help me ?
