I used to run Unity 2D on my work machine. Now I am trying to use Unity. Everthing looks fine except for the missing window decoration. I have installed the compiz manager. Every time I activate the plugin "window decoration" Unity "crashes" the Unity bar along with the top panel .
unity --reset oder replace does nothing.
The command for the window manager is /usr/bin/compiz-decorator
Maybe I need to specify another window decorator?
