Objectives to be achieved:

  • Installing Ubuntu 7.04
  • X graphical environment
  • Compiz window manager.
  • Use of multimedia (sound, video playback, ...).

I recompiled information from the following sources:

1. HOW-TO: Laptop LG Express Dual vs Ubuntu P1 6.06. -
2. Installing Ubuntu (7.04) Feisty Fawn with Beryl on ATI X1xxx. -
3. Compiz Fusion on Ubuntu Feisty with Xgl 7.04 the ATI Radeon Xpress 200M (32MB) (mini howto). -
4. Documentation for Ubuntu 7.04. -

From here I thank all the authors of these websites that have helped me (in all) to carry out my purpose.


1. Use distribution "Ubuntu 7.04 alternate i386".
2. Start the installation with the option "Install in text mode".
3. Select the language "Spanish - Spanish".
4. We make the choice for the detection of the keyboard.
5. When entering data network fails (normal) does not detect the ethernet. Mark "Continue".
6. Enter the name you want to give the team.
7. When partitioning the disk choose "Manual". Click on "FREE SPACE" and enter the space we want to give the linux partition. For example "3.5 GB". Mark "Primary" and then you place the "principle" of free space. Mark "has been completed to define the partition."
8. Return to click on "FREE SPACE" change in "Use as" and choose "swap area".
9. Mark "Peninsula".
10. We will request user data to be used by the system.

Start the graphical mode.

When you boot fail "X" so it does not start the graphical mode by default it shows a resolution that does not accept the card. To fix this run from a terminal:

sudo dpkg-reconfigure xserver-xorg

As points to be considered, you must select:

* Mode "vesa".
* Resolutions mark only "1200X800".

Once set up, run "startx".

Configure the wireless.

To perform the following steps we have set up a connection via WIFI. We do from the graphical mode.

Update the system.

From a terminal:

sudo apt-get update
sudo apt-get dist-upgrade (Download a 200Mbytes)

NOTE: It ends with the following error, but to ignore:
E: Sub-process / usr / bin / dpkg Returned an error code (1)

Installing fglrx (the proprietary driver from ATI).

sudo apt-get install xorg-driver-fglrx (Download a 18Mbytes)

NOTE: At the end again shows error (openoffice topics):

Errors were encountered while processing:
E: Sub-process / usr / bin / dpkg Returned an error code (1)

Update loaded modules:

sudo depmod-a

Configuration file / etc / X11 / xorg.conf:

sudo aticonfig-initial
sudo aticonfig-overlay-type = Xv


sudo shutdown-r now

Now the system boots with the correct driver, but without acceleration hardware. To activate:
System >> Administration >> Restricted Drivers Manager

Mark the check "Enabled" line "Driver for ATI graphics card acceleration." Accept the message shown below by checking "Enable the driver."

Reboot the system.

Install XGL:

sudo apt-get install xserver-xgl (2 be downloaded few Mbytes).

NOTE: ... still the same error (ignore).

Generate a file to start the XGL:

sudo nano / usr / local / bin /

copy the following contents:

#! / Bin / sh
Xgl: 1-fullscreen-ac-accel xv:-accel glx pBuffer: pBuffer &
cookie = "$ (xauth-i nextract -: 0 | cut-d ''-f 9)"
xauth-i add: 1. "$ Cookie"
exec dbus-launch-exit-with-session gnome-session

Give execute permissions:

sudo chmod a + x / usr / local / bin /

Create menu entry to access XGL mode:

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

Copy the following content:

[Desktop Entry]
Encoding = UTF-8
Name = GNOME with XGL
Comment =
Exec = / usr / local / bin /
Icon =
Type = Application

We execute permissions:

sudo chmod a + x / usr / share / xsessions / xgl.desktop

Now closed session and select options "GNOME with XGL".

Turn the speakers.

sudo nano / etc / modprobe.d / alsa-base

at the end add the following line:

options snd-hda-intel model = lg

Installing Compiz Fusion (Special Effects on the desktop).

From a console and is necessary to remove the following packages, in order to avoid conflicts with the default for Ubuntu Feisty:

sudo apt-get remove compiz compiz-core desktop-effects compiz-gnome

Usually when you run that command, removes all related packages.

Then edit our sources.list to add the repositories respective Compiz Fusion:

sudo nano / etc / apt / sources.list

And add the following lines:

# Compiz-fusion by Treviño's Ubuntu feisty EyeCandy Repository
feisty eyecandy deb
deb-src feisty eyecandy

Save the file. Now we have to validate the repositories:

gpg-keyserver-recv-keys 81836EBF
gpg -export -armor 81836EBF | sudo apt-key add -

Now we have to update the repositories:

sudo apt-get update

Then install the packages of Compiz Fusion:

sudo apt-get install compiz compiz-gnome compizconfig-settings-manager compiz-fusion-plugins-extra compiz-fusion-plugins-unofficial emerald emerald-themes-backend-gconf libcompizconfig

(Download a 12 Mbytes)

NOTE: After you must update the system but will not work. This is to avoid problems of compatibility packages.

sudo apt-get upgrade

Reboot, and start our session with acceleration 3D, Xgl (when starting the login, select Session> Xgl).

Now run in a terminal or console the following command:

compiz-replace && emerald-replace &

And presto, we have to witness the effects of Compiz Fusion 3D. And that starts when the machine, add the session in Preferences> Sessions> Startup Programs, the same command above.

To configure the effects, go to System menu, Preferences, and there select the CompizConfig settings manager to see all available options of effects and settings.
