There was an entry on Shuttleworth's blog about Beryl in universe. So I followed his advice and installed it, then fired it up. Boy, has Beryl come a long way since I installed it on my notebook under Suse 10.1. You can see a screen shot of the whole setup running below.
I've got the Beryl defaults for Ubuntu installed and enabled. And with all the effects running it looks and runs sweet. The screen shot above shows one of the new Beryl effects (new to me, anyway); a preview of any of the applications on the panel if the mouse pointer hovers over any given application. The screen shot shows the movie running in the middle of the desktop, and a thumbnail is also running in the lower right corner. And I mean running in the lower right corner. This is the exact same effect as what you'd find running Vista.
That AVI movie was ripped (transcoded) from a DVD to a 1GB MPEG-4 file. I performed the transcoding using K3B under Suse 10.2. I tried K3B under Ubuntu, but K3B's transcoding capabilities are broken under Ubuntu. Whatever.
With Beryl installed, all the little annoyances of running base Compiz seem to be swept away. Everything works. I can't wait for future Beryl releases. It's going to help every distribution that uses it, including Ubuntu. And to echo Mark, a super huge thank-you to everyone who worked so hard to get this to work under Feisty.
