I really a newbie to xfce. I was using gnome 2 orignally then since I'm using Arch Linux (64-bit), it was updated to Gnome 3. After long weeks of daily use, I didn't like gnome 3.
Now, I decided to use xfce. I did a fresh install (after formatting my hdd) of Arch, I put installed XFCE + SLIM login manager. Almost all works fine until I decided to install Compiz. After installing Compiz, for some reason gtk-window-decorator --replace (the one that you put under CCSM > Window Decoration > Command) does not work. Only "emerald --replace" and "kde4-window-decorator --replace" works. Unfortunately, I don't like emerald.
When I run gtk-window-decorator --replace in the terminal it gives me this error:
gtk-window-decorator: error while loading shared libraries: libmetacity-private.so.0: cannot open shared object file: No such file or directory
I made sure I installed the complete compiz+gtk package from pacman.
BTW, I never had a problem with gnome 2 + compiz + gtk-window-decorator. I don't know if I have to do something extra in xfce to make gtk-window-decorator work.
EDIT: FYI, I use fusion-icon as an autostart application for me to automatically start compiz during startup.
Please help a newb. Thanks!
