Install the following packages: sudo apt-get install beryl
Note: Beryl is a metapackage that will install all dependencies and decoration themes).
Starting Beryl
Now it's time to test Beryl. Open a terminal, and invoke: beryl-manager
If all goes well, Beryl should show a splash screen, and your windows will suddenly become wobbly! Also note that there is a new icon, a red gem, in your system tray - this allows you to control Beryl, run the Beryl settings manager or Emerald (the theme manager). It also provides fallback to a different window manager, in case Beryl crashes (remember Beryl is very much alpha software).
If you don't get a splash screen immediately, you may need to tell the manager to load Beryl - right-click on the icon in the system tray, go to "Select Window Manager" and choose "Beryl". If that doesn't work, there's a problem somewhere! Hopefully, useful debugging output will be in the terminal session; ask for help on the #ubuntu-xgl or #xgl channels on irc://irc.freenode.net/
Making Beryl start automatically when you log in (GNOME)
From the menu at the top of your screen, select "System > Preferences > Sessions". Click on the right-most tab, "Startup Programs".
Now create a new entry for beryl: beryl-manager
Close the Session Preference Panel. Beryl will now start automatically when you log in.
Troubleshooting
If you find that you cannot set icon or gtk themes while using beryl with Xgl on display :1, invoke the following command in a terminal: gnome-settings-daemon &
Your chosen theme should now appear.

The console message beryl: water: GL_ARB_fragment_program is missing
points to an OpenGL extension that your card cannot use. Simply switch off the water effect in the Beryl Settings Manager.

You might find that when you try to start beryl that you get the following: chris@ubuntu:~$ beryl
**************************************************************
* Beryl system compatiblity check *
**************************************************************

I fixed this by creating the following shell script in /usr/local/bin/start-beryl and adding it to the startup programs in Gnome. #!/bin/bash
LD_PRELOAD=/usr/lib/fglrx/libGL.so.1.2.xlibmesa /usr/bin/beryl &
gtk-window-decorator --replace &
xmodmap -e \"keycode 22 = BackSpace Delete\"
Many thanks to Michele Campeotto, who discovered this workaround for compwiz. From Michele's page:
"the problem is that ATI hasn’t yet released a driver with that new extension that Novell and NVIDIA developed specifically for Xgl and compiz.
The extension is implemented by Mesa though, so we need get compiz to use that. The problem is that when you install the fglrx driver it overwrites /usr/lib/libGL.so.1.2 with its own version wich lacks this feature."
No Window Decorator with an NVIDIA graphics card
If you've started beryl, and aren't getting a window decorator, the most likely cause is that ARGB GLX Visuals are disabled. There are two ways to fix this:
*NOTE* You should ALWAYS back up xorg.conf prior to tinkering with it.
Option 1: Using nvidia-xconfig (Preferred Method) Run the following command in a terminal session: sudo nvidia-xconfig --add-argb-glx-visuals This command invokes the nvidia-xconfig utility to add ARGB GLX Visual support to xorg.conf. This usually works quite well.
Option 2: Manually editing xorg.conf Run the following command from a terminal to open xorg.conf: sudo nano /etc/X11/xorg.conf Now, scroll down till you get to the section marked "Screen". You will then need to add in the following line to this section: Option "AddARGBGLXVisuals" "True" Now, save and exit.
After this is complete, restart X and all should be well.
