could not see any window decorator
i remember i have change some configuration in gconf-editor
and now if i logout my user and login to another user i have no window decoration also if i create new user account the default window decorator is missing and its have no theme
i try look at ubuntu-tweak and found no gtk themes & window themes (its both grayed out) in themes configuration
i tried to change from gconf-editor in apps>metacity>general set compositing manager to true but found no result
i also launch terminal and create start-up application with command "metacity --replace" (without quote) it dont work
i tried compiz --replace and enabled window decoration in ccsm still no window decoration

Please Helppppp....
