Ubuntu Feisty Installation Guide

The latest fglrx driver supports Radeon 9500+ and the X-series cards up to X1900.

Pre-Installation Checks

Enable "restricted" Repository

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

Disable Composite Extension

In Ubuntu Feisty the Composite extension is enabled by default, however, fglrx does not yet support Composite with DRI. In order to disable Composite you have to 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" "Disable" EndSection

• Note: Xubuntu does not have gedit. The default text editor in Xubuntu is called mousepad.
• Note: Kubuntu does not have gedit. The default text editor in Kubuntu is called Kate. Another option is to use nano.

Installation

Method 1: Install the Driver the Ubuntu Way

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

Method 2: Install the Driver Manually

• Note: This is an alternative installation method for the section above.

• Note: This method does not currently work on feisty, use Method 1 instead

Download the ATI driver installer: ati-driver-installer-8.33.6-x86.x86_64.run(this installer is for 32bit and 64bit systems), taking care of which version needs for your device.

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 fakeroot dh-make debhelper debconf libstdc++5 linux-headers-$(uname -r)

Create .deb packages:

sh ati-driver-installer-8.33.6-x86.x86_64.run --buildpkg Ubuntu/edgy

Install .deb packages:

sudo dpkg -i xorg-driver-fglrx_8.33.6-1*.deb
sudo dpkg -i fglrx-kernel-source_8.33.6-1*.deb
sudo dpkg -i fglrx-control_8.33.6-1*.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

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

Configure the Driver

sudo aticonfig --initial

• Note: 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.

sudo aticonfig --overlay-type=Xv

Finish the Installation

Now save any open document and reboot your system:

sudo shutdown -r now

• Note: An alternative to rebooting is to restart the X Server by pressing your CTRL+ALT+BACKSPACE keys. You must remove any old kernel modules such as "drm" "radeon" or "fglrx" using the "rmmod" command. Example: rmmod fglrx

Post-Installation Checks

Verifying

Run the following command to check its output to ensure the fglrx driver is installed properly:

$fglrxinfo
display: :0.0  screen: 0
OpenGL vendor string: ATI Technologies Inc.
OpenGL renderer string: MOBILITY RADEON 9700 Generic
OpenGL version string: 2.0.6286 (8.33.6)

Ubuntu-specific Issues

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
