hmm..i have another problem here
i creat simple shell script as you say..
compiz --replace ccp &
gtk-window-decorator --replace &
iam not to sure this is right script or not,i just find reference on google
and i saved it on /usr/local/sbin as executable file, than i put it on xfce4-autostart-editor..but when i restart my Xfce, Compiz not running.
thanks for every help..
