Ubuntu Breezy Installation Guide

2006-06-26T18:29:11Z

84.160.129.23: 8.26.18

== Method 1: Installing Breezy's Included Driver (8.16.20) ==

The fglrx driver supports Radeon 8500+ and the X-series cards (see [http://a248.e.akamai.net/f/674/9206/0/www2.ati.com/drivers/linux/linux_8.16.20.html#173867 release notes]). When running the dpkg-reconfigure commands you can accept the defaults whenever you aren't sure.

=== Installing the driver ===

''All Platforms:''
<pre>
sudo apt-get install xorg-driver-fglrx
sudo apt-get install linux-restricted-modules-$(uname -r) #Okay if it is already installed
sudo dpkg-reconfigure xserver-xorg #Select the fglrx driver and 64-bit users should deselect int10a
</pre>

''64-bit users:''

You have to downgrade to an older version of libdri.a due to an incompatilbity with the ATI drivers. [http://mail3.mpr.org/mlomker/libdri.a.gz Download it here]

Change to download directory:
<pre>
gunzip libdri.a.gz
sudo cp /usr/X11R6/lib/modules/extensions/libdri.a libdri.a.old
sudo cp libdri.a /usr/X11R6/lib/modules/extensions/
</pre>

If you wish to revert to any non-fglrx driver you will need to copy the libdri.a.old file back over the fglrx version.

''All platforms:'' Ctrl-Alt-Backspace to restart your desktop.

=== Confirm that it works ===
<pre>
$ fglrxinfo
display: :0.0 screen: 0
OpenGL vendor string: ATI Technologies Inc.
OpenGL renderer string: MOBILITY RADEON 9700 Generic
OpenGL version string: 1.3.5272 (X4.3.0-8.16.20)
</pre>

=== Troubleshooting ===

If you have a widescreen LCD display that is stuck at 1024x768 then it is probably the bug in the 8.16.20 driver that was fixed in 8.18.X (see the next section).

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

== Method 2: Generating/Installing Ubuntu packages for the newer 8.26.18 drivers in Breezy Badger ==

'''Important Warning:''' Installation of this driver requires removing the restricted-modules package in order to work. That package includes drivers for madwifi (Atheros wireless cards), nvidia cards, and a handful of other devices. I provide a work-around for the madwifi drivers, but you need to perform it before removing the restricted modules (jump to end of this this post).

When running the dpkg-reconfigure command you should answer the questions that you know and take the defaults for the rest. You might want to say ''no'' to the monitor detection--it has caused X-Windows to crash for some people.

=== Remove existing fglrx driver ===

Remove Breezy's included drivers if they are installed:

<pre>
sudo apt-get remove xorg-driver-fglrx
sudo apt-get remove fglrx-control
sudo apt-get remove linux-restricted-modules-$(uname -r)
sudo dpkg-reconfigure xserver-xorg #select the "ati" module
</pre>

Reboot.

*Note 1: If after reboot, your system hangs at a black screen before taking you to a graphical login - reboot to 'recovery mode' and edit /etc/X11/xorg.conf to use 'vesa' instead of 'ati'. Then continue with the steps below.

*Note 2: You can change your xorg.conf file to Option "vesa" BEFORE rebooting, so after rebooting you can have usable X (and skip Note 1). Remember that you HAVE to reboot (just restarting X will leave you with unusable X).

=== 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-8.26.18-x86.run 32bit Installer]

This guide refers to the 32bit version of the driver. If you are using a x86_64 System you need the [http://a248.e.akamai.net/f/674/9206/0/www2.ati.com/drivers/linux/64bit/ati-driver-installer-8.26.18-x86_64.run 64bit Installer]. The installation procedure 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. [http://mail3.mpr.org/mlomker/sources.list Sample sources.list].

''Install necessary tools:''

<pre>
sudo apt-get install gcc-3.4 module-assistant build-essential
sudo apt-get install fakeroot dh-make debconf libstdc++5 gcc-3.3-base
</pre>

''Create .deb packages:''

<pre>
chmod +x ati-driver-installer-8.26.18-x86.run
LANG=C LC_ALL=C ./ati-driver-installer-8.26.18-x86.run --buildpkg Ubuntu/breezy
</pre>

''Install .deb packages:''

<pre>
sudo dpkg -i xorg-driver-fglrx_8.26.18-1_i386.deb
sudo dpkg -i fglrx-control_8.26.18-1_i386.deb
sudo dpkg -i fglrx-kernel-source_8.26.18-1_i386.deb
</pre>

''Remove any old fglrx deb's from /usr/src/:''

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

''Compile the kernel driver:''

<pre>
sudo module-assistant prepare
sudo module-assistant update
sudo module-assistant a-i fglrx
</pre>

''Update the xorg.conf file:''

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

Reboot.

=== 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: 2.0.5879 (8.26.18)
</pre>

(''renderer string'' depends on your hardware and may/will be different)

=== Troubleshooting ===

==== General ====

Look for error messages in /var/log/Xorg.0.log and kern.log.
If you receive the (EE) No devices detected error message, is verry possible to own a radeon from 7000-7500 series witch the proprietary Linux drivers don't support the R100 chips (Radeon 7000-7500).

==== Madwifi Drivers in Breezy Badger ====
In order to continue using the [http://madwifi.org madwifi] driver you can do the following '''before''' removing the linux-restricted-modules package and rebooting.
<pre>
sudo cp /lib/modules/$(uname -r)/volatile/ath_hal.ko /lib/modules/$(uname -r)/kernel/
sudo depmod -a $(uname -r)
</pre>

Ubuntu Dapper Installation Guide

2006-06-26T18:26:16Z

84.160.129.23: /* Confirm that it worked */

== Method 1: Installing Dapper's Included Driver (8.25.18) ==

The included fglrx driver supports Radeon 8500+ and the X-series cards up to X1900. Note that if you own an ATi card from the R400 series or below, you already have 2D and may have accelerated 3D with the default drivers. These cards include:

* R400 series Xnnn (X800, X750, etc) (2D only)
* R300 series (9300+) (2D only)
* R200 and R100 series (9200 and below)

For specific chipsets and models, see [http://xorg.freedesktop.org/releases/X11R6.7.0/doc/radeon.4.html the Xorg 7.0 Release Notes].

The TV-Out functionality may not work with the open source drivers; if you don't have TV-Out or don't want to use it, however, then you probably don't need to use fglrx.

=== 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>

Reboot.

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: 2.0.5814 (8.25.18)
</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.

*It might be necessary to create a symlink to get accelerated OpenGL:
:<pre>sudo ln -s /usr/lib/dri /usr/lib/xorg/modules/dri</pre>

*AMD64 users: It may also be necessary to update /etc/profile if using GDM. Update the $LIBGL_DRIVERS_PATH variable to point to the dri path above.

*To ensure you automatically get the current ''linux-restricted-modules'' package with kernel updates, you should install the linux-restricted-modules-??? package matching your kernel-type (without version numer), e.g. ''linux-restricted-modules-386'', ''linux-restricted-modules-686'' or ''linux-restricted-modules-k7''.

*If you used Method 2 before, you have to unblacklist fglrx again by editing ''/etc/default/linux-restricted-modules-common''

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

 
== Method 2: Generating/Installing Ubuntu packages for the 8.26.18 drivers in Ubuntu Dapper Manually ==

'''Important Change:''' Installation of this driver '''no longer requires''' removing the linux-restricted-modules package in order to work. There is a new blacklist feature in Ubuntu Dapper that you can use to go around this.

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

<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-8.26.18-x86.run 32bit Installer]

This guide refers to the 32bit version of the driver. If you are using a x86_64 System you need the [http://a248.e.akamai.net/f/674/9206/0/www2.ati.com/drivers/linux/64bit/ati-driver-installer-8.26.18-x86_64.run 64bit Installer]. The installation procedure 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:''

<pre>
sudo apt-get update

<pre>
chmod +x ati-driver-installer-8.26.18-x86.run
./ati-driver-installer-8.26.18-x86.run --buildpkg Ubuntu/dapper
</pre>

''Install .deb packages:''

<pre>
sudo dpkg -i xorg-driver-fglrx_8.26.18-1_i386.deb
sudo dpkg -i fglrx-kernel-source_8.26.18-1_i386.deb
sudo dpkg -i fglrx-control_8.26.18-1_i386.deb
</pre>

''Remove any old fglrx deb's from /usr/src/:''

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

''Compile the kernel module:''

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

'''Note''': 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>

Reboot.

=== Confirm that it worked ===

<pre>
$ fglrxinfo

OpenGL vendor string: ATI Technologies Inc.
OpenGL renderer string: RADEON 9700 Generic
OpenGL version string: 2.0.5879 (8.26.18)
</pre>

=== Troubleshooting for Method 2===

==== Upgrade from Breezy ====
If method 2 doesn't work first time round, and you have upgraded from a Breezy installation, try this:

Remove previous versions of the fglrx driver:
<pre>
sudo dpkg -r fglrx-control
sudo dpkg -r fglrx-kernel-source
sudo dpkg -r xorg-driver-fglrx
</pre>

dpkg will list dependencies for xorg-driver-fglrx which will need up be removed, for example:

<pre>
sudo dpkg -r fglrx-kernel
sudo dpkg -r fglrx-kernel-2.6.12-10-686-smp
sudo dpkg -r xorg-driver-fglrx
</pre>

Proceed with method 2

 
== Troubleshooting for both Methods ==

=== General ===

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

=== HP Notebook dv5029us / zv6000 ===

If you have an HP Notebook Computer (or Compaq) such as the HP dv5029us or zv6000 series, it is needed to modify the BIOS configuration. It seems for some reason using sideport memory (the card's onboard memory only) leads to an apparent system crash although the logs show successful initialization of DRI. It is needed to run the BIOS setup screen, go to memory options, and select UMA+Sideport memory and assign a value to it (I assigned an extra 128M from the system RAM). Boot the computer and the fglrx driver will work. FGLRX version is 8.24.8 on an i386 Ubuntu Dapper install.

* Ubuntu FGLRX drivers 8.25.18, do not work properly on the dv5029us (Radeon Xpress 200M) as of this writing (5/30/2006). It is needed to revert to 8.24.8 for this specific computer in order to get proper 3D acceleration, and 2D with no tearing off.

=== HP zt3000 / Compaq nx7000 ===
Beginning with ATI driver version 8.19, the drivers fail to properly detect modelines that are compatible with the LCD screen of the HP zt3000 (and equivalent Compaq nx7000 model), and they must be inserted into xorg.conf manually. For the 1680x1050 LCD screen, inserting the following modelines into the "Monitor" section works:
Modeline "640x350" 119.12 640 1728 1760 1840 350 1052 1058 1080
Modeline "640x400" 119.12 640 1728 1760 1840 400 1052 1058 1080
Modeline "720x400" 119.12 720 1728 1760 1840 400 1052 1058 1080
Modeline "640x480" 119.12 640 1728 1760 1840 480 1052 1058 1080
Modeline "800x600" 119.12 800 1728 1760 1840 600 1052 1058 1080
Modeline "1024x768" 119.12 1024 1728 1760 1840 768 1052 1058 1080
Modeline "1152x864" 119.12 1152 1728 1760 1840 864 1052 1058 1080
Modeline "1280x960" 119.12 1280 1728 1760 1840 960 1052 1058 1080
Modeline "1280x1024" 119.12 1280 1728 1760 1840 1024 1052 1058 1080
Modeline "832x624" 119.12 832 1728 1760 1840 624 1052 1058 1080
Modeline "1280x768" 119.12 1280 1728 1760 1840 768 1052 1058 1080
Modeline "1280x800" 119.12 1280 1728 1760 1840 800 1052 1058 1080
Modeline "1152x768" 119.12 1152 1728 1760 1840 768 1052 1058 1080
Modeline "1400x1050" 119.12 1400 1728 1760 1840 1050 1052 1058 1080
Modeline "1440x900" 119.12 1440 1728 1760 1840 900 1052 1058 1080
Modeline "1600x1024" 119.12 1600 1728 1760 1840 1024 1052 1058 1080
Modeline "1680x1050" 119.12 1680 1728 1760 1840 1050 1052 1058 1080

If you have the "1920x1200" version of the HP zt3000 the Modeline is:
Modeline "1920x1200" 150.75 1920 2016 2048 2185 1200 1202 1208 1235

=== 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>

For the 1680x1050 LCD screen, inserting the following modelines into the "Monitor" section works:
Modeline "640x350" 119.12 640 1728 1760 1840 350 1052 1058 1080
Modeline "640x400" 119.12 640 1728 1760 1840 400 1052 1058 1080
Modeline "720x400" 119.12 720 1728 1760 1840 400 1052 1058 1080

Modeline "1400x1050" 119.12 1400 1728 1760 1840 1050 1052 1058 1080
Modeline "1440x900" 119.12 1440 1728 1760 1840 900 1052 1058 1080
Modeline "1600x1024" 119.12 1600 1728 1760 1840 1024 1052 1058 1080
Modeline "1680x1050" 119.12 1680 1728 1760 1840 1050 1052 1058 1080

If you have the "1920x1200" version of the HP zt3000 the Modeline is:
Modeline "1920x1200" 150.75 1920 2016 2048 2185 1200 1202 1208 1235

=== 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>
