== Unsupported adapter ==
Specific notes for Radeon HD 6xxx cards with no official support yet (see [[Hardware#Not_Yet_Supported_or_Unoffically_Supported]]).

After installing the fglrx module, you might get the following message when trying to configure X through aticonfig:
aticonfig: No supported adapters detected

Also you might see that the fglrx module has not been used by Xorg (no line saying ‘‘LoadModule: "fglrx"’’ in /var/log/Xorg.0.log). Also on my system I had segmentation faults from the ati Catalyst Control Center (amdcccle).

At this stage, do not panic! This does not necessarily imply a problem with the module, indeed your card may be not officially supported. Numerous reports on forums show that users end up using the drivers successfully anyway, e.g. for an HD 6850 card (BARTS codename). To force Xorg to load the driver for fglrx anyway, just manually create a minimal xorg.conf file, as suggested on this wiki (follow the tutorials). The module should then load and everything else should (hopefully) work. (On my system even the Catalyst Control Center was working at that point.) Except you have the "Unsupported hardware" mark on a corner of the screen, but that is another problem... (Forum users report they have been able to get rid of this as well, although caution should be used as the hack scripts seem not to work with version 11.1 of the Catalyst drivers.)

Talk:Glxgears is not a Benchmark

2011-07-14T15:43:55Z

204.236.254.63: /* Rather depends on how you define benchmark.. */

this leads to the obvious questions:

* what '''is''' a benchmark? please could someone provide a link..
* where can I get a list of benchmarks using something better than glxgears?

What an asweome way to explain thisnow I know everything!

Very true! Makes a chnage to see someone spell it out like that. :)

Ubuntu Dapper Installation Guide

2011-07-14T15:41:15Z

204.236.208.165: /* Troubleshooting for Method 2 */

'''NOTE:''' This guide is '''only''' for Ubuntu 6.06 (Dapper)! Guides for other versions of Ubuntu can be found at the [[Ubuntu]] page.

In Ubuntu Dapper 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 Dapper's Included Driver (8.25.18) ==

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

Unfortunately OpenGL seems to be broken for R200 cards (everything below Radeon 9500) in this driver version. The [[#Troubleshooting for Method 1|Troubleshooting]] section describes how to fix this '''after''' xorg-driver-fglrx is installed.

=== Installing the driver ===

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

Help on enabling repositories can be found at https://help.ubuntu.com/community/Repositories/Ubuntu.

<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>

Stein: For some reason I had to run "sudo apt-get install linux-restricted-modules-$(uname -r)" twice for it to properly install...

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: 2.0.5814 (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.

* Unfortunately OpenGL seems to be broken for R200 cards (everything below Radeon 9500) in this driver version which results in messages like
:<pre>[fglrx] API ERROR: could not register entrypoint for Uniform2iARB</pre>
:and similar when running OpenGL applications. This may be fixed by replacing ''/usr/lib/libGL.so.1.2'' with ''libGL.so.1.2'' from the previous driver version (8.24.8). To do so download this file: [http://files.covertprestige.info/important/libGL.so.1.2 libGL.so.1.2] and then copy it to the ''/usr/lib/'' directory.

*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''

*If the screen is coming up blank on startup, start in recovery mode then try editing your /etc/X11/xorg.conf file to remove this line
: <pre>Load "extmod"</pre>
: and optionally replace it with this
<pre>SubSection "extmod"
Option "omit XVideo"
Option "omit XVideo-MotionCompensation"
Option "omit XFree86-VidModeExtension"
EndSubSection</pre>

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

<br /><br />

I just happen to stumble on this page and it is a properly written read, a tad bit on the short side, but a fairly acceptable one.
I very much love the layout too, it is fairly simple to navigate.

== 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: MOBILITY RADEON 9700 Generic
OpenGL version string: 2.0.6286 (8.33.6)
</pre>

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

If your direct rendering is disabled then you may have to ensure '''fglrx_dri.so''' is where it should be. Try to symblink the '''dri''' folder if you get no direct rendering:

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

Gee willkeirs, thats such a great post!
