Finished

Just updated to Edgy and installed Beryl following these instructions.
Added these to my sources:
deb http://www.beerorkid.com/compiz edgy main-edgy
deb http://media.blutkind.org/xgl/ edgy main-edgy
deb http://compiz-mirror.lupine.me.uk/ edgy main-edgy
deb http://ubuntu.compiz.net/ edgy main-edgy
Then:
sudo apt-get update
Then, in /etc/X11/xorg.conf, since I use an Intel card, add to Section “Device”:
Option “XAANoOffscreenPixmaps” “true”

And at the end of the file:

Section "Extensions"  
Option "Composite" "true"  
EndSection

Then install Beryl: sudo apt-get install beryl-core beryl-plugins beryl-plugins-data emerald beryl-settings beryl-manager beryl beryl-dev emerald-themes Then just start with beryl-manager. Works like a charm, and quite fast too after tinkering with some effects and themes.
