I recently installed Compiz on Fedora 14 desktop taking a queue from your tutorial here:-http://www.howtoforge.com/enabling-compiz-fusion-on-a-fedora-14-gnome-desktop-nvidia-geforce-8100 I have enabled the Desktop Cube and Rotate Cube options in CompizConfig Settings Manager. The problem I am facing is the Desktop cube is as big as the Desktop itself even though I have set the zoom level in Rotate Cube to only 0.5000. Also the Skydome option is also not working. There is no effect on compiz when I change the Horizontal Virtual Size, Vertical Virtual Size and Number of Desktops in the Desktop Size tab of General Options. What could be the problem and the possible solution?
