Fedora 12 and Compiz (Settings Manager)

Fedora uses the older method of enabling Compiz, via the gconf plugin.

The “Desktop Effects” program under System -> Preferences runs the /usr/bin/compiz-gtk script (part of the compiz-gnome package) to enable Compiz, or fall back to Metacity (GNOME’s window manager).

gconf backend
The compiz-gtk script executes the command:
compiz --ignore-desktop-hints glib gconf gnomecompat

On systems here (with NVIDIA cards at least), the gconf backend package was not installed. This means that even though NVIDIA and 3D is all working, Compiz won’t start. So, installing the required gconf backend package should make it all work.

su -c 'yum -y install compizconfig-backend-gconf'

Now try again.

ccp backend
Upstream however, Compiz has moved away from gconf and is using libcompizconfig (ccp) and the CompizConfig Settings Manager (ccsm) to handle settings.

Installing the ccsm package under Fedora and changing Compiz settings using the graphical manager (CompizConfig Settings Manager) results in none of those taking effect.

This is because the compiz-gtk script is not loading the ccp module. So the workaround is to install ccsm and then modify the script to replace gconf with ccp.

su -c "sed -i 's/gconf/ccp/' /usr/bin/compiz-gtk"

Now try again.

Keep in mind that updated versions of the compiz-gnome package may overwrite this file, so you’ll need to edit it again in future if this happens.
