我想用桌面特效 卻Fatal: No sync extension

Pango853

我的OS : fedora 8 kernel 2.6.23.9-85
我安裝的驅動 : 由Ati.com 下的7.11 driver 跟所有 compiz package

[pango853@localhost ~]$ fglrxinfo
display: :0.0 screen: 0
OpenGL vendor string: ATI Technologies Inc.
OpenGL renderer string: Radeon X1950 Series
OpenGL version string: 2.1.7059 Release  （這裏正常）

[pango853@localhost ~]$ glxinfo
name of display: :0.0
display: :0 screen: 0
direct rendering: Yes       （這裏也正常）
server glx vendor string: SGI
server glx version string: 1.2
server glx extensions:
GLX_ARB_multisample, GLX_EXT_import_context,
...................


[pango853@localhost ~]$ desktop-effects
compiz (core) - Fatal: No sync extension      
Xlib: extension "SHAPE" missing on display ":0.0".
Xlib: extension "SHAPE" missing on display ":0.0".
Xlib: extension "SHAPE" missing on display ":0.0".
...
這裏問題來了，一走桌面特效它說要這個shape??
