Big Fat Warning

Read this before doing anything else!

This is NOT a tested guide for Ubuntu Edgy. It is just a modified copy of the Dapper-Guide. Maybe it works for you, maybe it will make your system unusable. If you are using Edgy and you really know that some parts of this guide have to be modified to make the install work in Edgy, please change them accordingly.

On the other side, if you can confirm that this guide (this means both methods) works on an a default Edgy installation without causing any trouble, you may remove this warning.

Method 1: Installing Edgy's Included Driver

Disable Composite Extension

In Ubuntu Edgy the Composite extension is enabled by default. However, fglrx does not yet support Composite with DRI. Therefore you have to disable Composite. To do so edit the xorg.conf file: 

sudo gedit /etc/X11/xorg.conf

and add these lines at the end of the file:

File: /etc/X11/xorg.conf 
Section "Extensions"
        Option  "Composite" "0"
EndSection

Installing the driver

Make sure the restricted repository is enabled in /etc/apt/sources.list or this guide will not work! 

sudo apt-get update
sudo apt-get install linux-restricted-modules-$(uname -r) #Okay if it is already installed
sudo apt-get install xorg-driver-fglrx
sudo depmod -a
sudo aticonfig --initial
sudo aticonfig --overlay-type=Xv

Now Reboot your system: 

sudo shutdown -r now

An alternative to the aticonfig --initial command is to edit /etc/X11/xorg.conf and replace the string "ati" with "fglrx" in the "Device" section. This way you won't lose your old "Screen" and "Monitor" settings. Afterwards you can use aticonfig for setting overlay etc.

Confirm that it works

fglrxinfo
display: :0.0  screen: 0
OpenGL vendor string: ATI Technologies Inc.
OpenGL renderer string: RADEON 9600 Generic
OpenGL version string: 2.0.5814 (8.25.18)

Troubleshooting for Method 1

  • The output of dmesg | grep fglrx and /var/log/Xorg.0.log are most useful when looking for errors. You should really include this when you are asking for help somewhere.
  • If you used Method 2 before, you have to unblacklist fglrx again by editing /etc/default/linux-restricted-modules-common



Method 2: Generating/Installing Ubuntu packages for the 8.28.8 drivers in Ubuntu Edgy Manually

Blacklist old fglrx module from linux-restricted-modules

We have to blacklist the fglrx module from linux-restricted-modules to make sure the new kernel module (which will be created during install) will be used instead. 

sudo gedit /etc/default/linux-restricted-modules-common

Edit DISABLED_MODULES to include fglrx

File: /etc/default/linux-restricted-modules-common 
DISABLED_MODULES="fglrx"

Disable Composite Extension

In Ubuntu Edgy the Composite extension is enabled by default. However, fglrx does not yet support Composite with DRI. Therefore you have to disable Composite. To do so edit the xorg.conf file: 

sudo gedit /etc/X11/xorg.conf

and add these lines at the end of the file:

File: /etc/X11/xorg.conf 
Section "Extensions"
        Option  "Composite" "0"
EndSection

Installing the new driver

Download the ATI driver installer: ati-driver-installer-8.28.8.run (this installer is for 32bit and 64bit systems)

This guide refers to the 32bit version of the driver. The installation procedure for 64bit should be the same as for 32bit, except some filenames will differ slightly.

Change to the download directory. Make sure that you have the universe and multiverse repositories enabled in /etc/apt/sources.list before doing these steps.

Install necessary tools: 

sudo apt-get update
sudo apt-get install module-assistant build-essential 
sudo apt-get install fakeroot dh-make debconf libstdc++5 linux-headers-$(uname -r)

Create .deb packages: 

sudo ln -sf bash /bin/sh
bash ati-driver-installer-8.28.8.run --buildpkg Ubuntu/edgy
sudo ln -sf dash /bin/sh

Install .deb packages: 

sudo dpkg -i xorg-driver-fglrx_8.28.8-1_i386.deb
sudo dpkg -i fglrx-kernel-source_8.28.8-1_i386.deb
sudo dpkg -i fglrx-control_8.28.8-1_i386.deb

Remove any old fglrx debs from /usr/src/: 

sudo rm /usr/src/fglrx-kernel*.deb

Compile the kernel module: 

sudo module-assistant prepare
sudo module-assistant update
sudo module-assistant build fglrx
sudo module-assistant install fglrx
sudo depmod -a

Note: You have to recompile the kernel module after each kernel update!

Update the xorg.conf file: 

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

Reboot: 

sudo shutdown -r now

Confirm that it worked

$ fglrxinfo
display: :0.0  screen: 0
OpenGL vendor string: ATI Technologies Inc.
OpenGL renderer string: RADEON 9700 Generic
OpenGL version string: 2.0.6011 (8.28.8)

Troubleshooting for Method 2

xorg.conf

The aticonfig --initial command will not update the xorg.conf file if it already has a "fglrx" Device section. However, you may force aticonfig to generate default Monitor, Device, and Screen sections with the following command: 

sudo aticonfig --force --initial




Troubleshooting for both Methods

General

The output of dmesg | grep fglrx and /var/log/Xorg.0.log are most useful when looking for errors.

2D speed

If you suffer from slow 2D speed it might help to set 

Option		"XaaNoOffscreenPixmaps"

in the fglrx section of /etc/X11/xorg.conf

Is the rebooting really necessary?

No.

However, rebooting is the easiest method to ensure that the kernel module(s) from the old driver are unloaded and the fglrx module is loaded instead. If you don't want to reboot for some reason, you may manually shut down Xorg, unload any old "drm", "radeon" or "fglrx" modules and then start Xorg again.

Revert to Xorg driver

If (for any reason) the fglrx install fails, you can revert to the Xorg driver by executing 

sudo dpkg-reconfigure xserver-xorg

and selecting the "ati" driver, or simply restoring the previous /etc/X11/xorg.conf file, if you made a backup.

You also need to remove the xorg-driver-fglrx or your manually installed drivers to get the 3D acceleration back, since it is provided by file /usr/lib/libGL.so.1.2 which belongs to libgl1-mesa package and which is moved to backup and replaced at the installation of xorg-driver-fglrx (or the manually built) package. In case the removal of the fglrx drivers fails to restore the file from libgl1-mesa, you have to reinstall the package by running: 

sudo apt-get install --reinstall libgl1-mesa
