https://bbs.archlinux.org – Have you installed "ccsm"?  That will let you enable features such as window borders and being able to move and resize windows.  You will also need to install a window decorator such as "emerald".  Read the Compiz Wiki entry for specific instructions.  Also, what desktop environment are you using?   Which video drivers are you using, nouveau or proprietary?  If you are using full-blown GNOME 3, instead of just it's panel, then Compiz is incompatible with GNOME shell so you will have to use the fallback mode.  Again, see the Wiki (HowTos)
