Compiz Fusion is really great and – so far – stable enough !
I decided to drop Compiz since I found out (thanks to the Powertop utility by Intel) that it was power monger.
Result :
Compiz : 3h30
Metacity : 5h00
It is still under heavy development but already nice, usable and quite stable.
I have been using it for 2 weeks now, and did not get any freeze. It just does not have all the options I am sure it will get in the future.
I have run Beryl for months and have seen many huge and nice improvements.
I switched to Beryl soon after the fork from Compiz. At the time, I was on Ubuntu Breezy. The reason of my switch was a major issue with Compiz, making it impossible for my laptop to hibernate. Beryl did it. I could have solved it by myself, maybe, but didn’t have time to dig out desktop things.
Today, it is again some bugs that pushed me to switch back from Beryl to Compiz.
