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

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

In /etc/X11/xorg.conf.

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.
