First make sure you have 3d acceleration available in a normal gnome session. There are lots of howtos for this , Google if you need any help with that. So if glxinfo shows direct rendering: yes , then you are good to go. If not xgl and Beryl wont work!

sudo aptitude update
sudo aptitude dist-upgrade

• Make a startup script for xgl

sudo gedit /usr/bin/startxgl

#!/bin/sh
Xgl :1 -fullscreen -ac -accel xv:pbuffer -accel glx:pbuffer &
DISPLAY=:1
exec dbus-launch --exit-with-session gnome-session

• Make the script executable

sudo chmod +x /usr/bin/startxgl

• Make a xgl session for the login manager

sudo gedit /usr/share/xsessions/xgl.desktop

• Add to /usr/share/xsessions/xgl.desktop

[Desktop Entry]
Encoding=UTF-8
Name=Xgl
Comment=Start an Xgl Session
Exec=/usr/bin/startxgl
Icon=
Type=Application

• System > Preferences > Sessions > Startup Programs > Add

beryl-manager

• Reboot
• In the login manager you can now choose a session named Xgl
• Answer to following question that you want to use Xgl for this session only (if something went wrong you are logged in next time using standard session)
• If everything works fine , you can set it as the default session , remember you can always login a normal gnome session if you want.

• If you own an x series radeon and have problems with lockups, read this post:

Note for all cards: glxinfo will show that direct rendering is not working , dont worry thats normal when you are running xgl.
