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 MOBILITY RADEON 9600/9700 Series
+
OpenGL version string: 2.0.6650 (8.40.4)
+
</pre>
+
The <code>OpenGL vendor string</code> should read '''ATI''' and not '''Mesa'''.
+
 
+
If you see a message like 'Xlib: extension "XFree86-DRI" missing on display ":1.0"' then you may have to add the following to /etc/X11/xorg.conf (see [http://ubuntuforums.org/showthread.php?t=292642#post1714920]):

{{Box File|/etc/X11/xorg.conf|

<pre>
+
Section "Extensions"
+
    Option "Composite" "Disable"
+
EndSection
+
</pre>
+
}}
+

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

For example: <br>
+
* 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

Tocuhdwon! That's a really cool way of putting it!

If suspend is not working

If suspend stops working after fglrx installation, meaning display will not initialize after attempting to resume, then changing a few options has been reported to work for some hardware.


For ATI X700 and ATI X1100 on Acer Aspire 5051:

File: /etc/default/acpi-support
SAVE_VBE_STATE=false
POST_VIDEO=true
USE_DPMS=false

For ATI X1300 and the ATI X1400 on a Dell Inspiron 9400 or Lenovo Thinkpad T60, also for ATI X1600 on Asus Z96J (using install method 2):

File: /etc/default/acpi-support
POST_VIDEO=false
