Dear xfce/lxde user/maintainer, perhaps you know i re-retired compiz-0.88 for f18. I also added a start-script for lxde and xfce, subpackage compiz-xfce and compiz-lxde. Unfortunately i do not use xfce or lxde directly so i have no feedback if compiz is running well in those desktop. I did a short test if i had created the packages, and it was OK.
It wold be nice if some could test it more and give me a feedback.
Thank you Wolfgang
PS: compiz is running well in gnome-fallback
