Install Xgl + Compiz

sudo cp /etc/gdm/gdm.conf-custom /etc/gdm/gdm.conf-custom-backup
sudo gedit /etc/gdm/gdm.conf-custom

Scroll to the bottom of the file and replace "servers" section with the following lines, then save the file.

[servers]# Override display 1 to use Xgl
0=Xgl 

[server-Xgl] 
name=Xgl server 
command=/usr/bin/Xgl :0 -fullscreen -ac -accel glx:pbuffer -accel xv:fbo 
flexible=true

Edit your sources.list (sudo gedit /etc/apt/sources.list) and add the following line to the bottom:

deb http://gandalfn.club.fr/ubuntu edgy dev

Save the file. You must also download the gpg key by running the following command:

gpg --keyserver hkp://wwwkeys.eu.pgp.net --recv-keys 0x483170E9 ; gpg --export -a 0x483170E9 | sudo apt-key add -

After doing the above you must update apt-get:

sudo apt-get update
sudo apt-get dist-upgrade

Now install necessary packages + depencies:

sudo apt-get install compiz compiz-extra compiz-plugins compiz-extra-plugins gnome-compiz-manager gnome-compiz-manager-extra xserver-xgl

To start Compiz you can type the following into a terminal:

compiz-tray-icon

You should then see a Compiz icon on your gnome panel. Right click on it and select "GL Desktop".You may also want to add this command to your session start-up programs list.

Troubleshooting
- If Xgl/Compiz doesn't seem to work, or you get errors, simply restart your machine. (Recommended)

How to install Xgl/Beryl (ATI)

(From Beryl Forums) (Also From Ubuntu Forums)

Read #General Notes
Read #How to install Graphics Driver (ATI)

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!

Update your system

sudo aptitude update
sudo aptitude dist-upgrade

Prepare and update repositories

sudo gedit /etc/apt/sources.list

Add to /etc/apt/sources.list

##BERYL REPOSITORIES
deb http://ubuntu.beryl-project.org edgy main
deb-src http://ubuntu.beryl-project.org edgy main

##BERYL SVN REPOSITORIES
deb http://download.tuxfamily.org/3v1deb edgy beryl-svn
deb-src http://download.tuxfamily.org/3v1deb edgy beryl-svn

Download and import the gpg key for beryl & beryl svn project repositories

wget http://ubuntu.beryl-project.org/root@lupine.me.uk.gpg -O- | sudo apt-key add -
wget http://download.tuxfamily.org/3v1deb/DD800CD9.gpg -O- | sudo apt-key add -

Update your sources

sudo aptitude update

Install needed packages

sudo apt-get install xserver-xgl libgl1-mesa xserver-xorg libglitz-glx1 beryl \
beryl-core beryl-manager beryl-plugins beryl-plugins-data beryl-settings emerald \
emerald-themes

Make a startup script for xgl

sudo gedit /usr/bin/startxgl

Add to /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:

http://ubuntuforums.org/showthread.php?t=150854

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

How to install Beryl/AIGLX (Nvidia)

(From Ubuntu Forums)

Read #General Notes
Read #How to add extra repositories
Read #How to install Beta Graphics Driver (NVIDIA)

Ensure all packages up to date

Install your *ubuntu-desktop metapackage specific to your DE, e.g. sudo apt-get install ubuntu-desktop
sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade

Add repositories

gksudo gedit /etc/apt/sources.list

Add the following line at the end of this file (x86 and amd64):

deb http://ubuntu.beryl-project.org/ edgy main

Add key

wget http://ubuntu.beryl-project.org/root@lupine.me.uk.gpg -O- | sudo apt-key add -

Save the edited file then update package lists

sudo apt-get update

Install Beryl

sudo apt-get install beryl emerald-themes

Back up xorg.conf

sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf_backup
gksudo gedit /etc/X11/xorg.conf

Add this to xorg.conf "Screen" section

# Enable 32-bit ARGB GLX Visuals
    Option "AddARGBGLXVisuals" "True"

# If you are using an older version of compiz that
# does not support rendering into the Composite
# Overlay Window, you will need to disable clipping
# of GLX rendering to the X Root window with this
# option, or you will get a blank screen after
# starting compiz:
    Option "DisableGLXRootClipping" "True"

Add this to xorg.conf "Device" section

Option          "TripleBuffer" "true"

Restart X with ctrl+alt+backspace

Start Beryl (if it doesn't start on its own)

beryl-manager

Start Emerald (if it doesn't start on its own)

emerald --replace

Have Beryl and Emerald load on login
- System -> Preferences -> Sessions
- Startup Programs -> Add

beryl-manager

and

emerald --replace

- If, on reboot, program menus aren't displaying in the correct layer (you can't see them when you select them because they are displaying behind the window) then right click on the 'Beryl Manager' icon in the panel (the red gem icon) and select 'Reload Window Manager'. The problem should be solved the next time you reboot.

Some users have found that the latest beryl packages are not working properly, and beryl fails to load. This can be fixed by:

Open synaptic package manager, search for beryl, press ctrl+e and select version 0.1.99.2 You have to do this for beryl, beryl-core, beryl-manager, beryl-plugins, beryl-plugins-data, beryl-settings, beryl-settings-binding, libberyldecoration0 and libberylsettings0

How to install Beryl/AIGLX (Intel i915)

Follow the how-to on beryl project wiki.

If that does not work, check if you have direct rendering enabled (type into the terminal):

glxinfo | grep direct

The output should be:

direct rendering: Yes

If the output says No, check you have direct rendering manager loaded:

lsmod|grep 915

The output should be:

i915   21632  3
drm    74644  4 i915
tsdev   9152  0

If it shows only tsdev line, you can try to configure xorg.conf to driver i810, restart, CTRL-ALT-F1 to terminal session and configure xorg.conf back to use i915. That helped me.

How to install alternate boot splash screen

Read #General Notes

This installs a minimalistic splash screen that appears when the computer is booting up and shutting down. It is devoid of any text messages.

sudo aptitude install usplash
wget -c http://www.users.on.net/~stubby/usplash-minimalistic_0.1.deb
sudo dpkg -i usplash-minimalistic_0.1.deb
sudo update-alternatives --config usplash-artwork.so

Select the minimalistic alternative (/usr/local/lib/usplash/minimalastic.so) by entering the corresponding number. If you ever want to revert back to the original splash, select the default (/usr/lib/usplash/usplash-default.so)
