I've got a bug that is reoccuring (no window chrome close/minimize/maximize buttons) that is solved by changing the visual effects level (e.g. from none to normal).
Unfortunately, the desktop is relatively unusable until I change that setting upon each login.
I have the inclining that it might be solved by resetting compiz to it's default settings. How would I go about resetting compiz (or whatever is in charge of those visual effects) to it's defaults?
