Ubuntu Edgy Installation Guide

2011-06-02T15:07:20Z

196.35.68.58: /* Disable Composite Extension */

In Ubuntu Edgy you can choose between two methods of installing the proprietary ATI driver. If you are new to linux you should use the first method as it is a lot easier than the second one and will work well in most cases. The second method describes how to install the very latest driver version, but requires some additional work and knowledge.

== Method 1: Installing Edgy's Included Driver (8.28.8)==

The included fglrx driver supports Radeon 8500+ and the X-series cards up to X1900.

Thanks for shanrig. What a pleasure to read!

=== Installing the driver ===

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

<pre>
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
</pre>

Now Reboot your system:

<pre>
sudo shutdown -r now
</pre>

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 ===
<pre>
fglrxinfo
display: :0.0 screen: 0
OpenGL vendor string: ATI Technologies Inc.
OpenGL renderer string: RADEON 9600 Generic
OpenGL version string: 2.0.6011 (8.28.8)
</pre>

=== 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''. You may have to run '''sudo lrm-manager''' afterwards.

*See [[#Troubleshooting for both Methods|Troubleshooting for both Methods]]

 

== Method 2: Generating/Installing Ubuntu packages for the new 8.30.3 drivers in Ubuntu Edgy Manually ==

The new fglrx driver supports Radeon '''9'''500+ (older cards will not work!) and the X-series cards up to X1900.

=== Disable Composite Extension ===

In Ubuntu Edgy the Composite extension is enabled by default, however, ''fglrx'' does not yet support Composite with DRI. In order to to disable Composite you have to edit the ''xorg.conf'' file:
<pre>sudo gedit /etc/X11/xorg.conf</pre>
and add these lines at the end of the file:
{{Box File|/etc/X11/xorg.conf|
<pre>Section "Extensions"
Option "Composite" "Disable"
EndSection</pre>
}}

=== Blacklist old fglrx module from linux-restricted-modules ===

As ubuntu's ''linux-restricted-modules'' package includes the fglrx module from an old driver version (8.28.8), we have to blacklist this module to make sure the new kernel module which is needed by the new driver will be used instead.

<pre>sudo gedit /etc/default/linux-restricted-modules-common</pre>
Edit ''DISABLED_MODULES'' to include fglrx
{{Box File|/etc/default/linux-restricted-modules-common|
<pre>DISABLED_MODULES="fglrx"</pre>
}}

=== Installing the new driver ===

Download the ATI driver installer: [http://a248.e.akamai.net/f/674/9206/0/www2.ati.com/drivers/linux/ati-driver-installer-8.30.3.run ati-driver-installer-8.30.3.run] (this installer is for 32bit '''and''' 64bit systems)

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:''

<pre>
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)
</pre>

''Create .deb packages:''

<pre>
sudo ln -sf bash /bin/sh
bash ati-driver-installer-8.30.3.run --buildpkg Ubuntu/edgy
sudo ln -sf dash /bin/sh
</pre>

''Install .deb packages:''

<pre>
sudo dpkg -i xorg-driver-fglrx_8.30.3-1*.deb
sudo dpkg -i fglrx-kernel-source_8.30.3-1*.deb
sudo dpkg -i fglrx-control_8.30.3-1*.deb
</pre>

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

<pre>
sudo rm /usr/src/fglrx-kernel*.deb
</pre>

''Compile the kernel module:''

<pre>
sudo module-assistant prepare
sudo module-assistant update
sudo module-assistant build fglrx
sudo module-assistant install fglrx
sudo depmod -a
</pre>

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

''Update the xorg.conf file:''

<pre>
sudo aticonfig --initial
sudo aticonfig --overlay-type=Xv
</pre>

'''Note:'''
You could also edit your ''/usr/X11/xorg.conf'' file to change your driver to '''fglrx''' then run:

<pre>
sudo aticonfig --overlay-type=Xv
</pre>

This way your ''xorg.conf'' file will stay clean.

''Now Reboot:''

<pre>
sudo shutdown -r now
</pre>

=== Confirm that it worked ===

<pre>
$ fglrxinfo
display: :0.0 screen: 0
OpenGL vendor string: ATI Technologies Inc.
OpenGL renderer string: RADEON 9700 Generic
OpenGL version string: 2.0.6119 (8.30.3)
</pre>

<pre>
$ glxinfo | grep render
direct rendering: Yes
</pre>

If your direct rendering is disabled, you may have to symlink the dri folder:

<pre>
sudo mkdir /usr/X11R6/lib/modules
sudo ln -s /usr/lib/dri /usr/X11R6/lib/modules/
</pre>

=== 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:

<pre>
sudo aticonfig --force --initial
</pre>

 

=== The module compiles, but doesn't work ===
For some reason fglrx may need gcc-4.0 to compile, if you experience some message related to gcc version in dmesg, try this:

First we'll install it

<pre>
sudo apt-get install gcc-4.0
</pre>

and link it to gcc.

<pre>
sudo ln -sf /usr/bin/gcc-4.0 /usr/bin/gcc
</pre>

After doing the module-assistant steps, you may want to return gcc to 4.1 by default:

<pre>
sudo ln -sf /usr/bin/gcc-4.1 /usr/bin/gcc
</pre>

== Troubleshooting for both Methods ==

=== General ===

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

=== DRI does not work although the fglrx module is loaded ===

If fglrxinfo shows:
<pre>
OpenGL vendor string: Mesa project: www.mesa3d.org
</pre>

Make sure the Composite extension is disabled, add this to your /etc/X11/xorg.conf file:
<pre>
Section "Extensions"
Option "Composite" "Disable"
EndSection
</pre>

This should also resolve the corrupted mouse cursor problem in dual-head mode.

=== Module isn't loaded ===
If the fglrx module isn't loaded try to add ''fglrx'' to /etc/modules on a new line. See also [https://launchpad.net/distros/ubuntu/+bug/63912 bug 63912].

{{Box File|/etc/modules|
<pre>
# /etc/modules: kernel modules to load at boot time.
#
# This file contains the names of kernel modules that should be loaded
# at boot time, one per line. Lines beginning with "#" are ignored.

fglrx
</pre>
}}

=== 2D speed ===

If you suffer from slow 2D speed it might help to set
Option "XaaNoOffscreenPixmaps"
in the fglrx device 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.

Note: if ''modprobe fglrx'' can't find the ''fglrx'' module, try rebuilding your kernel module dependency:

<pre>
sudo depmod -a
</pre>

=== Revert to Xorg driver ===

If (for any reason) the fglrx install fails, you can revert to the Xorg driver by executing
<pre>sudo dpkg-reconfigure xserver-xorg</pre>
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:

<pre>sudo apt-get install --reinstall libgl1-mesa</pre>

Ubuntu Gutsy Installation Guide

2007-12-07T20:17:42Z

196.35.158.179:

The [[:Category:Releases|latest]] fglrx driver supports Radeon 9500 and the X-series cards up to HD2900. Workstation cards are not supported.

==Pre-Installation Checks==
=== Enable "restricted" Repository ===
Make sure the ''restricted'' repository is enabled in ''/etc/apt/sources.list'' or this guide will not work!

System > Administration > Software Sources. Check "Proprietary Drivers for Devices (Restricted)" box.

== Installation ==

For most users it won't be necessary to go into installation and configuration details of the driver. Ubuntu 7.10 (Gutsy) provides a notification saying that there are restricted drivers available. You just have to go there (Restricted Drivers Manager) and enable the "ATI accelerated graphics driver". Ubuntu will then install and configure the driver for you. If this does not provide the optimal solution you were looking for, please read ahead.

===Method 1: Install the Driver the Ubuntu Way===
This will install the driver that is currently in the repositories. It may be older than the current version from AMD.
<pre>
sudo apt-get update
sudo apt-get install linux-restricted-modules-generic restricted-manager
sudo apt-get install xorg-driver-fglrx
sudo depmod -a
</pre>

Note: The second line of the above may not be necessary. If apt says it cannot find the "linux-restricted-modules" package, try line 3. If that fails, check your sources.list (see top of page)

If the system complains about dependencies, use your preferred package manager to download python2.4 and, if necessary, its dependencies.

(Note: This method did not work with ATI X1300 Radeon on Gutsy whereas method 2 worked perfectly for us. 26/10/2007)

===Method 2: Install the Catalyst 7.11 Driver Manually===

*Note: ''This is just an alternative installation method for the section above. It might help if you still get 'DRI missing' errors.''

*Note: ''If you are running the -rt kernel, you will fail to compile the kernel module with ''"FATAL: modpost: GPL-incompatible module fglrx.ko uses GPL-only symbol '__rcu_read_lock'"''.''

Download the ATI driver installer:
[https://a248.e.akamai.net/f/674/9206/0/www2.ati.com/drivers/linux/ati-driver-installer-7-11-x86.x86_64.run ati-driver-installer-7-11-x86.x86_64.run] (this installer is for 32bit '''and''' 64bit systems)

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.

There is a detailed manual with screenshots at [https://wiki.ubuntu.com/AddingRepositoriesHowto Ubuntu Wiki].

By default, Ubuntu did not enable the Universe and Multiverse repositories, but now in Gutsy, both Universe and Multiverse are activated by default.

''Install necessary tools:''
<pre>
sudo apt-get update
sudo apt-get install module-assistant build-essential fakeroot dh-make debhelper \
debconf libstdc++5 linux-headers-generic
</pre>

''Create .deb packages:''

<pre>
sudo bash ati-driver-installer-7-11-x86.x86_64.run --buildpkg Ubuntu/gutsy
</pre>
note: if this step fails with a signal being caught, and you are running the script on an NFS-mounted directory, copy it to a local partition, and it will work.

If this step fails on amd64/x86_64 with a <tt>No such file or directory</tt> message about missing files in <tt>X11R6/lib</tt>, [http://emmetcaulfield.net/tech/Ubuntu64+ATI follow these instructions] and come back here. Also check that your downloadpath does not contain spaces.

''Blacklist old fglrx module from linux-restricted-modules:''

As Ubuntu Gutsy's ''linux-restricted-modules'' package includes the fglrx module from an old driver version (8.37.6), we have to blacklist this module to make sure the new kernel module which is needed by the new driver will be used instead.

Ubuntu/Gnome users type in:
<pre>gksu gedit /etc/default/linux-restricted-modules-common</pre>

Kubuntu/KDE users type in:
<pre>kdesu kate /etc/default/linux-restricted-modules-common</pre>

Add "fglrx" to the line "DISABLED_MODULES"
{{Box File|/etc/default/linux-restricted-modules-common|
<pre>DISABLED_MODULES="fglrx"</pre>
}}
Please note that after the modification above, the "Restricted Driver Manager" will signal "ATI accelerated grapichs driver" not enabled (unticked). This is perfectly correct. At the end of the installation procedure it will signal in Status: "in use" (green light), but NOT enabled. It simply means that the fglrx module contained in the linux-restricted-modules package is not enabled, but another fglrx module (7.11) is in use.

''Install .deb packages:''

<pre>
sudo dpkg -i xorg-driver-fglrx_8.433-1*.deb fglrx-kernel-source_8.433-1*.deb fglrx-amdcccle_8.433-1*.deb
</pre>

*Note: If you get a 'Bad file descriptor' message concerning the xorg.conf file try switching user to root and repeating the same command without sudo. This might be valid for the following commands too. (Ubuntu Gutsy installs with no password set for root by default. You can set a password for the root by typing 'sudo passwd root' first.)

*Note: If you have a 64 bit install, the above dpkg command will likely complain that "Errors were encountered while processing: fglrx-amdcccle". This is because of a dependency of the amdccle package on 32 bit libraries. If you recieve this error, issue the following command after the above dpkg command, which will force the installation of all of the 32 bit dependencies, and then the amdccle pacakge:

<pre>
sudo apt-get install -f
</pre>

''Remove any old fglrx debs from /usr/src/:''
<pre>
sudo rm /usr/src/fglrx-kernel*.deb
</pre>

''Fix broken dependencies''
*Note: ''You only need to do this if you have installed previous versions of these drivers using this method before.''
<pre>
sudo apt-get -f install
</pre>

''Compile the kernel module:''
<pre>
sudo module-assistant prepare,update
sudo module-assistant build,install fglrx -f
sudo depmod -a
</pre>

It's necessary, because sometimes this file is written by other packages, and so there's no 3D acceleration.
Check that the file /lib/modules/$(uname -r)/misc/fglrx.ko has been created.

''Create the following folder''

<pre>
sudo mkdir /lib/modules/$(uname -r)/volatile
</pre>

Note: the volatile directory might already exist at this stage then simply continue with the next step.

''Create a symbolic link''

<pre>
sudo ln -sf /lib/modules/$(uname -r)/misc/fglrx.ko /lib/modules/$(uname -r)/volatile/fglrx.ko
</pre>

NOTE : On my Gutsy install, after a reboot this link was always removed automatically leaving me without an fglrx module loaded, and thus no ATI rendering. There have been several ways of getting around this suggested here, and here is the one that worked for me:

<pre>
sudo gedit /etc/init.d/ati-module-fix
</pre>

And put this in it:
<pre>
#!/bin/sh -e

# For loading ATI display drivers

ln -sf /lib/modules/$(uname -r)/misc/fglrx.ko /lib/modules/$(uname -r)/volatile/fglrx.ko
exit 0

</pre>

Make it executable

<pre>
sudo chmod ugo+x /etc/init.d/ati-module-fix
</pre>

Now, make this run ''before'' gdm (which starts with sequence number 13)

<pre>
sudo update-rc.d ati-module-fix defaults 12
</pre>

It is possible that gdm sequence number is different. To find the gdm sequence number:
<pre>
ls /etc/rc2.d/
</pre>
And substitute 12 in the previous command with gdm sequence number - 1.

'''IMPORTANT''': You have to recompile the kernel module after each kernel update!
(Note: This does not affect you until the next time you update your kernel.)

Comment the following line in the file /etc/modprobe.d/lrm-video { add at 27/11/2007 }
<pre>
# Make nvidia/nvidia_legacy and fglrx use /sbin/lrm-video to load
#install fglrx /sbin/lrm-video fglrx $CMDLINE_OPTS # << this line
install nvidia /sbin/lrm-video nvidia $CMDLINE_OPTS
install nvidia_legacy /sbin/lrm-video nvidia_legacy $CMDLINE_OPTS
install nvidia_new /sbin/lrm-video nvidia_new $CMDLINE_OPTS
</pre>

===Configure the Driver===
*Note Method 2 Users: Before you carry out this step you must reboot your machine. Or else the fglrx driver will not be in use on xorg.conf and using the aticonfig options will cause a memory dump and not intialise the Driver properly.
*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. Another alternative is '''aticonfig --initial --force''' if you encounter issues with the first command.
<pre>
sudo aticonfig --initial
</pre>
Then:
<pre>
sudo aticonfig --overlay-type=Xv
</pre>
*Note: Alternative in the overlay-type to "Xv" can be "opengl" or "disable" if the TV-out makes problems in videos.

====Alternative: Configure the Driver, The Manual Way:====
An alternative to the "''sudo aticonfig''" commands is to edit "''/etc/X11/xorg.conf''" and change the "Device" section for the video card as shown below. This way you won't lose your old settings.
<pre>
gksu gedit /etc/X11/xorg.conf
</pre>
<pre>
Section "Device"
[...]
# Driver "vesa"
Driver "fglrx"
Option "VideoOverlay" "on"
Option "OpenGLOverlay" "off"
[...]
EndSection
</pre>

===Finish the Installation===
Now save any open document and reboot your system:
<pre>
sudo shutdown -hr now
</pre>
*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: <code>sudo rmmod fglrx</code>

== Post-Installation Checks ==
===Verifying===
Run the following command to check its output to ensure the fglrx driver is installed properly:
<pre>
$ fglrxinfo
display: :0.0 screen: 0
OpenGL vendor string: ATI Technologies Inc.
OpenGL renderer string: ATI Radeon Xpress Series
OpenGL version string: 2.1.7059 Release
</pre>
The <code>OpenGL vendor string</code> should read '''ATI''' and not '''Mesa'''.

'''If it still says ''Mesa'' and not ''ATI'', even after re-enabling the driver from the Restricted-manager:'''
You can try the following:
:*Remove all the packages provided by the <code>xserver-xorg-video-all</code> meta-package (search for it using Synaptic or Adept), then restart the machine. The X Server should now use the new fglrx driver by force (provided the driver is being used in ''xorg.conf'').
::If you can't log in after this, you'll have to log in to a terminal in the login screen, and reinstall the <code>xserver-xorg-video-all</code> package. Your problem is probably somewhere else. (taken from [http://ubuntuforums.org/showpost.php?p=3655658&postcount=139]).

'''If it says '' libGL.so.1: cannot open shared object file: No such file or directory''...'''
Check if you have a ''/usr/lib/libGL.so.1.2'', if so do this:
<pre>sudo ln -s /usr/lib/libGL.so.1.2 /usr/lib/libGL.so.1</pre>

Note: Can somebody post a glxinfo from a good install?

=== 3D desktop effects ===
The new ATI drivers use AIGLX so there is not need to install XGL that older drivers (< 8.40) required.

Remove this section from to the /etc/X11/xorg.conf file.
The new xorg server enables "Composite" by default.
<pre>
# Section "Extensions"
# Option "Composite" "0"
# EndSection
</pre>

Compiz does not know about the fglrx driver. You can either skip the checks

<pre>mkdir -p ~/.config/compiz && echo SKIP_CHECKS=yes >> ~/.config/compiz/compiz-manager</pre>

or add it to the compiz white list, and clear the blacklist pci Ids variable '''*Recommended*'''

<pre>sudo gedit /usr/bin/compiz</pre>

<pre>
# Driver whitelist
WHITELIST="fglrx nvidia intel ati radeon i810"
</pre>

<pre>
# blacklist based on the pci ids
# BLACKLIST_PCIIDS="$T"
BLACKLIST_PCIIDS=""
</pre>

After the necessary configurations, just restart X and enjoy the cool effects.

For Kubuntu you need some extra steps:
<pre>
sudo apt-get install compiz compiz-kde compizconfig-settings-manager compiz-core compiz-fusion-plugins-main compiz-plugins
</pre>

To test 3D Effects, press ALT+F2 and type "compiz --replace".

To configure use the tool KMenu->Settings->Avanced Desktop Effect Settings.

=== Additional configure with aticonfig tool ===
You can configure the driver even further with the '''aticonfig''' tool, more information can be found at [[Configuring]].

For example: 
* use powerplay option to switch power state for battery friendly or performance mode
* use dual head or one big desktop mode
* turn second monitor on/off on the fly

==Ubuntu-specific Issues==

=== If installing 8.42.3 on Ubuntu x64... (fglrx 7.11 does not require this)===

(thanks to Michael at Phoronix forums and aolana at Ubuntuforums.org)

Building packages for Ubuntu 64-Bit is known to be broken. If you're installing on Ubuntu 64-Bit, do this:

Download this: [http://www.michaellarabel.com/downloads/fglrx-8.42-ubuntu+debian-2.tar.bz2 fglrx-8.42-ubuntu+debian-2.tar.bz2]

Extract the installer:

<pre>
bash ati-driver-installer-8.42.3-x86.x86_64.run --extract somedirectory
</pre>

Extract the archive you downloaded to the directory that you extracted the driver's installation files to.

Then build the package:

<pre>
./ati-installer.sh 8.42.3 --buildpkg Ubuntu/gutsy
</pre>

=== Revert to Xorg driver ===

If (for any reason) the fglrx install fails, you can revert to the Xorg driver by executing
<pre>sudo dpkg-reconfigure xserver-xorg</pre>
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:

<pre>sudo apt-get install --reinstall libgl1-mesa</pre>

=== Attention: Suspend/Hibernation will not work===

With Gutsy release, there's a big problem using any version of the ATI proprietary drivers. The Suspend/Hibernate function will stop working.
The problem is due to the new SLUB allocator incorporated in 2.6.22 / 2.6.23 Kernel.
There are no workaround, except:

- Boot using the older kernel (ver 2.6.20)

- Return to Feisty (with 2.6.20 kernel, and apply specific solutions: see Feisty installation guide).

- Use default Mesa Drivers (the easiest way is to disable ATI driver from Restricted Driver Manager).

- Recompiler your Kernel to use SLAB.

Unfortunately some new ATI cards couldn't start X with Mesa drivers, so the only workaround is returning to Feisty.

'''The problem was supposed to be solved in the AMD Catalyst 7.11 driver release (supporting the 2.6.23 kernel), but it is not.'''

A similar problem appears with nVidia cards. No explanation or workaround has been forthcoming.

===If you get /usr/X11R6/lib/modules/dri/fglrx_dri.so not found===

sudo ln -s /usr/lib/ /usr/X11R6/lib/modules

=== libGL error ===
* fglrxinfo gives: libGL.so.1: cannot open shared object file.
* Fixed with command:
sudo ln -s /usr/lib/libGL.so.1.2 /usr/lib/libGL.so.1
