Compiz is now available in fedora.
Differents from former fedora packages:
-- version is stable 0.8.8
-- gtk-windows-decorator is droped
because all windows-manager which i can use as base for gwd (metacity, marco)
are ported to gesettings, in result gwd doesn't work correctly.
So, emerald is the default and only windows-decorator.
-- gconf2/mateconf backend is droped
Default configuration backend is ini files, which is used by 'ccsm'.
compiz-mate contains the matecompat plugin and a start script 'compiz-mate-emerald'.
This you can add with dconf-editor to key desktop/mate/session/required-components/windowmanager.
compiz-lxde contains a start script 'compix-lxde-emerald' which can added in lxde preferenes as windows-manager.
compiz-xfce contains a start script 'compix-xfce-emerald'
simply add to autostart, i don't know a solution like in mate or lxde.
Have fun and feel free to test compiz
For new users and those who have forgot
compiz doesn't support gnome-shell
